Is the control done only once? Also, for doing 3 tried per experiment, is it ok to do 3 at the same temperature together? As in, warm them in the same water bath and time them together.
Hi! Enzymes don't get used up as they are catalysts, meaning that they're unchanged during a reaction. Substrates on the other hand are converted into a product, so they are used up. :)
I think you have to say that all substrates are used up because the dependent variable here is the concentration of product which relates to the substrate more as substrates are converted to the product in enzyme reactions.

could you do more practical videos like this because as you know due to the current situations practical work cannot be undertaken. Great video
thank you this is very helpful! honestly seeing it written is just as helpful as seeing it done as a practical in person
In the last question, I said you don't need to use comparative words like "faster", but you in fact do, I just messed up my words!
Your explanations are on point I like how you explain even the smallest details really helpful
Wow thank you! This must have taken you ages! Very useful. Looking forward to the rest of the series😊
Thank you very much for this video. It is very useful. Could you please make videos on practical 3,4,7,8 and 9? Thank you :)

At 17:42, How do you know its the substrate that has been used and not actual enzyme/active site?

thank you so much this , video was so well explained and really helpful !!!!!!!1
this is so helpful! thank you!
You're welcome ☺️
Thank you for this!
can you not say that all the enzymes active sites have been saturated instead of all substrates are used up how would i know which to use??????
do i just assume its the substrate
