Unformatted text preview: (a) one molecule of NADH Answer: 1 NADH molecule oxidation pumps 10 H + and ~3.3 H + needed to make 1 ATP; therefore, 10/3.3 = ~3 ATPs (b) one molecule of FADH 2 Answer: 1 FADH 2 molecule pumps 6H + and ~3.3 H + needed to make 1 ATP; therefore, 6/3.3 = ~1.5  2 ATPs 3.) (a) (2 Points ) What is the purpose of the malateaspartate shuttle? Answer: The malateaspartate shuttle is used to carry reducing equivalents of NADH from the cytosol into the matrix for the electron transport chain to occur, while regenerating cytosolic levels of oxaloacetate. 4.) ( 2 Points ) What is the chemiosmotic hypothesis? Answer: A proton gradient is what drives the formation of ATP....
