Question

At the complete end of cellular respiration, how many molecules of ATP are produced?Question 20 options:A) 34B) 15C) 38D) 26

Answer 1

To answer this question we needd to remember how meny ATP, NAD and FAD are produced on each step of cellular respiration, so the account is a follows:

Glycolisis, 2ATP, 2NADH = 6ATP

Aerobic phase (krebs cycle, Acetil CoA), 4ATP, 2FADH, 8NADH= 32 ATP

Now we must remember that in glycolysis we spent 2ATP so the net production of the whole process is 38 ATP minus 2 ATP, which gives us 36ATP.

Therefore we can say that the correct answer is option C as 38 ATP are produced in total.
