The energy source that drives the production of ATP in oxidative phosphorylation is


A) the removal of electrons and hydrogen from glucose.
B) the removal of a phosphate group from a substrate that is then added to ADP.
C) the capture of solar energy that donates electrons.

The citric acid cycle starts with ________ and yields


A) lactic acid; carbon dioxide.
B) glucose; 32 ATPs.
C) acetyl CoA; lactic acid or alcohol.
D) acetyl CoA, NAD, FAD, and ADP; carbon dioxide, NADH, FADH2, and ATP.
E) carbon dioxide; oxygen. The citric acid cycle starts with the products from the preparatory step that meet up with C4 molecules already present in the mitochondrial matrix. Two carbons are pulled off and released as carbon dioxide, leaving a C4 molecule allowing the process to occur again. Both NAD+ and FAD accept hydrogen atoms, resulting in NADH and FADH2.

B) ATP acts as a power source for the citric acid cycle, while NADH serves as energy to run the cell.
C) ATP acts as a power source for performing cellular work, while NADH serves as an electron carrier to allow for greater ATP production.
D) ATP acts as an electron acceptor, while NADH serves as a way to break up glucose to form pyruvate.
E) ATP acts as a power source for performing cellular work, while NADH acts as a power source for photosynthesis.
