Please correct me if I'm mistaken, but I believe the antennae complex ONLY refers to the accessory pigments and not the whole photosystem (1:55). quote: "The light-harvesting complex (or antenna complex) is an array of protein and chlorophyll molecules embedded in the thylakoid membrane of plants, which transfer light energy to one chlorophyll a molecule at the reaction center of a photosystem"
Exam Time yaa u are partially correct ...The Lhc are made up of hundreds of pigment molecule and each photosystem has all the pigments (except ***one **molecule of chl a ) forming light harvesting sys called anntena molecule .... that means rest chl a mol. Are included in anntena mol.. Hope it helps .
I believe you are correct. To quote the NCERT book, "Each photosystem has all the pigments (except one molecule of chlorophyll a) forming a light harvesting system also called antennae."
mam u r simply the best I would not be wrong if I say I have not seen any teacher explaining photosynthesis so simply..Mam I m preparing for MSC entrance can u make a guiding video for the same...

How can someone dislike the video...i just dnt understand!!!!!! This are the basics and one must knw this to study further. And with this much concept clearity ...its awsm 😘
Mam you a best bio teacher for me i commented frst time but i m following u from long time.....i always wish for yr gud health bcz i don't know why but i feel a conection with u u always help me alot........thank u soo much mam love u and god bless u
Thank you so much ma'am for your videos m a final year student but because of this pandemic situation it was getting really tough to study..but because of your videos m able to study n it's so concept clearing.
Ma'am ur explanation was asm.... can't be compared with any one... The way u say... Very calmly it turns a difficult portion to a easy portion Thank you ma'am..

crystal clear just crystal clear. this is the easiest way to put these concepts i guess. u r totally awesome mam plz continue the gr8 work and answer in the comment section too(if time permits)
mam i appreciate you but according to book atp is formed in photosystem1 and the hydrogen in NADPH is coming from stroma of chloroplast,plz confirm it.....
I think that with the simple addition their was also increase in efficiency of both ps as they must be containing some accessory pigment have the absorption in the other wavelength (which got activated)
light harvting complex ,,means two photosystemmmm,,,,,each quantasome form a photosystem,,,,,,there r 230 chrofil mols in each quantasome or photosystem
mam the maximum absorption takes place in blue and red light . the wavelength of red light is 680nm and that of blue is 450nm, but we got photosystem 1 of 700nm and photosystem 2 of 680nm so it absorb the light of wavelength between 680-700nm but what for blue light is there any photosystems for blue light
please do correct me if i am wrong. i believe chlorophyll a is meant to absorb RED light (since it only absorbs wavelengths of 680nm and 700nm) however, there are other components that absorb different colours of light in the photosystems. a component called chlorophyll b absorbs ORANGE and BLUE light. meanwhile, another component called the carotenoid components absorb BLUE-GREEN light. so to answer your question, technically both existing photosystems absorb all colours *including blue*, but excluding green (which is why plants exude the colour green). hope this helps!
tyara keena That explains it. But it may not be correct. According Engelmann's experiments, chlorophyll a shows maximum absorption in both the red and blue regions of white light. Even I don't know the correct answer. Please share if you could think of something.
Asalamualikum bhai....It is clearly written in NCERT that "The reaction centre is different in both the photosystems"...Thats why their absorption peak is different in both the photosystems....😊
Mam I just love you.........u teacher is just out of d world........for u I even skiped my bio tuitions......nd .....only by ur tutorial m doing much better.........😘😘❤️❤️

acc to helix institute notes , it's correct...
Sukhwinder Kaur helix notes? is that reliable?
Far better then unacademy , vedantu any many more i wasted my time there glad found this channel
Thanks a lot mam
I was highly confused while reading ncert
But after going through your lectures i m easily able to understand everything .
8:08 photosystem 1
Hats off to you ma'am !! Never seen such an amazing teacher like you. You made it extremely easy to understand. Thanks a ton ma'am !
mam u r simply the best
I would not be wrong if I say I have not seen any teacher explaining photosynthesis so simply..Mam I m preparing for MSC entrance can u make a guiding video for the same...
Mam but in ncert it is given that the anntenae doesn't includes the reaction centre.
Yes actually can you please clear my doubt now?
So the phtosystem doesn't not include chlorophyll a molecule,it includes only accessory pigment?
@@bhvya8945 no ,chl a is the main, it absorb most of the light. And it is also called reaction centre.
Each and every topic u teach is crystal clear in my mind... I am a B. Sc. Student still ur videos play great role in achieving excellent marks.

Happy Teachers' Day Ma'am 😊 5th September, 2020
What is the difference between Quantosome and antenna complex?
i'm having a test tomorrow, your video is so helpful to me, great job, keep up😇
Ur best bio teacher mam thankw 😊😊😊
Thank you so much ma'am for your videos m a final year student but because of this pandemic situation it was getting really tough to study..but because of your videos m able to study n it's so concept clearing.

Best teaching.Thank you so much mam🙏🙏.Very helpful. Ithrem nannayi vere aarum padipichitilla😊
Your explanation is so good that you should write a biology book or module of students
Mam, i understand that their are two different PS but mam how they made more or when they were both illuminated with the suitable wavelengths
mam accessory pigment sirf absorb karte hai kya aur utilise nahi karte?
very very helpful mam and u make all topics very simple and easy
And u say that the chl-a id uncluded in the antennae...?plz rply mam
Mam what is light harvesting protein?
Is that same as quantosome
Wonderful, wonderful, wonderful. One day, I hope to hire you.
crystal clear just crystal clear. this is the easiest way to put these concepts i guess. u r totally awesome mam plz continue the gr8 work and answer in the comment section too(if time permits)

Perfect way of teaching
Mam,what is the difference between light harvesting complexes and quantosomes?or,are they similar??
light harvting complex ,,means two photosystemmmm,,,,,each quantasome form a photosystem,,,,,,there r 230 chrofil mols in each quantasome or photosystem
@@NetBio-Senpai thankyou so much sir😊
Thank you!!! This was very helpful.
How does Antenna complex include Cholorophyll?
It is amazing video and helped me a lot..
Thnx mam, you have translated it really well..
I do my studies only because of u... Thanx a lot mam🙏😘
reaction centre absorb nahi karta kya sirf utilise karta hai, please mujhe bataiye ga,
It's truly helpful Neela mam
What is the meaning of Light harvesting complex...?
Mam your explanation is really the best...
Thank you so much mam.Really a great work😊
Is core complex and antenna complex is the same thing..
Is quantasome and light harvesting complex the same
Same

What is primary acceptor of electron????????????????
Gaur Gaud ..... primary accepter of electron means.... which receive s the two electrons which comes from the ch a by light rekn
Ferrodoxin
thnxx a lot ma'am its really vry hlpful....no words 2 say anythng about ur way 2 teach....thnxxx
Awesome !!! Mam. Really you are great biology teacher. I will saw regularly your lecture
best lectures LOVE FROM PAKISTAN :)
Thank u for teaching us😚😚
Mam. Can I write this for mechanism of quantum capture of light energy
Thank u mam for this amazing vdo u are the best mam😊😊
best teaching ever!!!!!!!!!!!!!!!!!!!!!!!!!
mam NCERT mein toh antenne without chl-a kaha gaya hai
So easily understandable....Thank you mamm......

Mam ur videos are super-duper we don't feel to come out of it great job mam thanks for ur efforts
if both are chlorophyll a Molecule with the same accessory pigments than
what makes them absorb different wavelengths?
Asalamualikum bhai....It is clearly written in NCERT that "The reaction centre is different in both the photosystems"...Thats why their absorption peak is different in both the photosystems....😊
Mam chl a is same in both photosystem than why there is wavelength difference???plzzz answer
becz different accessory pigments present around absorb light of different wavelength
You are a very good teacher.😊
Mam I just love you.........u teacher is just out of d world........for u I even skiped my bio tuitions......nd .....only by ur tutorial m doing much better.........😘😘❤️❤️

If both are chlorophyll a how they absorb different wave length..?
In addition to chl a in the reaction centre,PS-II has accessory pigments that help to absorb light from different wavelengths........Hope it helps :)
Is it correct according to ncert or as said by u...?
Ma'am you haven't mentioned about photolysis of water.. where does it occur? Inside pigment system or where? Someone please Explain mechanism.
It is discussed in the later part of the chapter dude!
Excellent teaching mam😊😊😊
If there is chl a in both photosystem then why PSI absorbs 700nm and PSII absorbs 680 nm?
mam,but why should there be a red drop?What is the reason behind it
is there only a single molecule of chlorophyll a present in the photo system
very useful and thnkful to u for these lectures...
Mam you are great
I love the way you explain 🤗🤗🤗
Best and silmpest method thank you soo much mam
Thank u so much mam your videos are of great help..clearing all the concept..thnks alot
All pigments except chlorophyll a are called as accessory pigments or antenna pigments
What a great explaination!
