Heart rate or pulse I think.
Answer:
The correct answer is - a. NADH
Explanation:
The Krebs cycle is a set of chemical reactions that takes place to generate energy from nutrients such as carbohydrates, fats, and proteins converting to carbon dioxide. by oxidation of acetate.
In the Krebs cycle, each molecule of carbon generates 3 molecules of NADH, one molecule of ATP and 2 molecules of FADH2 in each cycle. Thus, the greatest numbers during one turn of the Krebs cycle is NADH.
Adenine always pairs with Thymine, and Cytosine always pairs up with Guanine in DNA. When dealing with RNA, however, Uracil replaces Thymine. So in RNA, A pairs with U and C pairs with G. (just a fun fact) :)
