Here is the core biology course for ATP overview: 6 O2 + C 6 H 12 O 6 -> 6 CO2 + 6 H2O + ATP oxygen + glucose -> carbon dioxide + water + energy Cellular respiration is the process that releases energy by breaking down food molecules in the presence of oxygen. Glycolysis takes place in the cytoplasm. The Kreb cycle and electron transport take place inside the mitochondria. Glycolysis is the process in which one molecule of glucose is broken in half, producing two molecules of pyruvic acid of a 3 carbon compounds. During the Kreb cycle, pyruvic acid is broken down into carbon dioxide in a series of energy extracting reactions. The electron transport chain uses the high-energy electrons from the Krebs cycle to convert ADP into ATP.
Hello Khan Academy friends, DP biology teacher here (similar to AP). One thing I want to make clear that is video does not is about the points in time where energy is released and absorbed (needed). There are a few processes where bonds are formed and broken in the model shown. In chemistry, when bonds are formed energy is released. Energy is needed, or absorbed, when a bond needs to be broken. Yes this includes the phosphate group bond in ATP!!! Even though the phosphate group bonds are unstable, it is still a form of stability which needs energy to break it (some people replace unstable with high energy, this is why I tend to disagree with that terminology). It just happens to be that the formation of the bond with the phosphate group and the oxygen in the water molecule is more stable and thus releases the energy. The placement of energy before and after in the system comes out to mean energy is released in this chemical reaction, but that is from the formation of the bond with water rather then the breaking of ATP.
You're the best. I had trouble grasping ATP + Cellular respiration in my Biology Workbook for Dummies, in which you actually explain it straightforward, get into the heart and core of the details later and in which they fit. Thank you.
It does take energy to recreate ATP from ADP and P, but it is important to note that making a bond involves a release of energy. The actual creation of the bond between P and ADP would release a bit of energy, but overall the creation of the unstable ATP from the more stable ADP would require energy. Similar to the hydrolysis of ATP, which overall releases energy because such stable products are formed from unstable ATP, but involves an initial absorption of energy to actually break the bond of the third phosphate. It's tricky and I've always been confused about the way it was taught, until recently.
Who understands the phagocytosis process of Lysosomes and the functions of Rough Endoplasmic Reticulum? And what is the purpose of the Golgi Complex? Can you explain the four stages of cell division? Etc.
The energy stored in ATP isn't due to the negative charges of pohosphate groups? they normally tend to repulse each other but as they are kept together by the energy of the bond when they split they release that energy. Here is my curiosity: ATP can just split only one phosphate group but not the second one... Is possible that even the second phosphate group could be split? In that case it would release energy anyways (I presume), probably a lower amount of it but it could happen because of the repulsion between the second and the first phospate grupo (the one attached to the ribose).
How can we benefit from the energy we get by ATP Hydrolysis? By phosphorylation or by using the released energy (i think it is called gibbs energy) or both ways?
so basically when carbs protiens and fats are digested the energy taken from them is made into ATP so when the body needs energy the ATP turns into ADP with energy ? but what happens to ADP afterwards ??
Okay, im not comprehending something. ATP is the currency for energy. When we use energy we are using ATP. But, ADP is considered energy released and ATP is considered energy stored?
yes ATP still has the three phosphors and thus the high energy stored within it, but when ATP -> ADP + P the energy is thus released, due to the broken bond
Imagine, the power station use ATP to generate electricity instead of coal, petroleum & nuclear.. We also get hydrogen as a bonus instead of greenhouse gas through methane reforming

I've watched like 5 videos about ATP and have read a lot of articles about it. Thankfully i found this.
Same! Nobody explains it in a way that makes sense to me!!
Still don’t get it now lol

yes
Michael Qing 😍😍😍😍😍😍😍
Glucose comes before oxygen
Whats kreb cycle? Whats pyruvic acid?

Huh, funny coincidence how this video is uploaded while I'm studying for my Bio final tomorrow
This video not help anybody.
How did your exam go?
no I hate bio actually lol. It was in high school, i'm in college now for chem eng
How'd it go?

Thanks, I was discussing this topic with my friend a year ago. Now I know what is happening.
Can you clear what do you mean by energy?
sometimes , I benefit from such comment rather than watching content !
quiet good explanation ...
Wow I have some crazy Friday nights, I'm sat here watching a video about ATP.
Excellent in all aspects.. especially voice of narrator...as of Robert Kayun. Thanks 🙏.
I must commend the instructor. This is an excellent representation of ATP.
Next topic: NADPH etc.
You're the best. I had trouble grasping ATP + Cellular respiration in my Biology Workbook for Dummies, in which you actually explain it straightforward, get into the heart and core of the details later and in which they fit. Thank you.
Great explanation! A level deeper than most I've seen...
thank you so much, I'm from Brazil and I'm not an english fluent, but I could understand everything!!

I was so confused about that as well until now that I read this comment so thank you for making it a bit clearer!
Why tetra pants phosphate is not used is energy
Creatine can provide that phosphate to ADP.
Perfect timing as I'm studying ATP now.
Omg semoga diberkahi, semoga dimudahkan segala urusannya untuk yg buat sub Indonesia 🙏
Thanks for this content Khan
Simple and awesome.
Thank u ❤️
Who understands the phagocytosis process of Lysosomes and the functions of Rough Endoplasmic Reticulum?
And what is the purpose of the Golgi Complex? Can you explain the four stages of cell division? Etc.
Thanks alot its so helpful
قل هو الله أحد الله الصمد لم يلد ولم يولد ولم يكن له كفؤا أحد
You actually helped me a lot
👍. From 🇹🇷 Turkey.

Great as always Khan Academy!
How can we benefit from the energy we get by ATP Hydrolysis? By phosphorylation or by using the released energy (i think it is called gibbs energy) or both ways?
Equation, right side has a error. Charge is wrong.
good
so basically when carbs protiens and fats are digested the energy taken from them is made into ATP so when the body needs energy the ATP turns into ADP with energy ? but what happens to ADP afterwards ??
I have questions: why ATP is called energy currency of cell not ADP (have same band),
LOOOOOVE YOU ...
can red light stimulate or pro
ite ATP?
Is the Adenine with ribose, and 1 phosphate group (AMP) the same as the nucleotide used in nucleic acids?
Why dont we have GTP, TTP or CTP as an energy currency?
atp is just what the cell is used to using !
GTP can be seen in the cycle of Krebs
Okay, im not comprehending something. ATP is the currency for energy. When we use energy we are using ATP. But, ADP is considered energy released and ATP is considered energy stored?
yes ATP still has the three phosphors and thus the high energy stored within it, but when ATP -> ADP + P the energy is thus released, due to the broken bond
nice, thx
What is an energy? A flying electron?
big help thax
When adenosine triphosphate becomes adenosine diphosphate, Calorie occurs.
Imagine, the power station use ATP to generate electricity instead of coal, petroleum & nuclear.. We also get hydrogen as a bonus instead of greenhouse gas through methane reforming
You so mean to me :(
I wrote German captions for the old ATP video, not long ago!
love the metaphors :D
You saved me from getting bad score
All Saudi student love you
why we take in more oxygen when we come from run
Thnks for the video. But you didn't help out on the funtions .
Why did the body choose this? Why is it bioavailable?
Why is atp unstable?
because the phosphates are all negative charged and bonded together
2:22
Yo mr Gregg anyone ee
Why body not store energy is adenosin tetra phosphate..penta...
Because why not not do that
what... to much information someone help me.
i think i know this voice from somewhere
I think its dr sam Robins
I think he also doesn’t algebra videos
Sir Hindi m bhi explane kya kre plz
why do you watch this in your free time?
Far a gradeeedeeeeseeeeeeee I wish i had history
Because I love science
