Question

QUESTION 1 Choose the reason(s) why ATP is used as the primary source of cellular energy: Check all that apply. ATP is kinetically stable. ATP has the highest phosphoryl group transfer potential out of all of the phosphorylated compounds in the cell The concentration of ATP in cells is fairly high, making the actual free energy of hydrolysis very negative. ATP hydrolysis results in products that are at a lower energy state than the substrate, thus making it a highly exergonic reaction. QUESTION2 Which of the following compounds can donate a phosphoryl group to ADP? O PEP (phosphoenolpyruvate) O Glyceraldehyde 3-P DHAP OPyruvate QUESTION 3 Ethanol and lactate fermentation reactions regenerate the following coenzyme for glycolysis: NAD NADH O FADH2 O NADPH

Explanation / Answer

Question.1

answer. ATP has the highest group transfer potential out of all the phosporylated compunds in the cell.

Because ATP contains three phosphate groups. These groups are primarily responsible for ATP's role as an energy source.

Question.2

answer.PEP(phosphoenolpyruvate)

Question.3

answer. NAD+
