Level 1: Knowledge/Comprehension
- 1. The immediate energy source that drives ATP synthesis by ATP synthesis during oxidative phosphorylation is the

(a) Starting with one molecule of glucose, how many ATPs are produced during (I) aerobic and (II) anaerobic respiration? (b) In chemiosmotic (oxidative) phosphorylation, what is the most direct source of energy that is used to convert ADP + Pi to ATP and what the driving force for the ATP formation through ATP synthase?
State whether each statement is true or false. If the statement is false, correct it so it can be true.
(a) Oxidative phosphorylation generates heat by converting ADP to ATP.
(b) The effects of a poison on actively respiring mitochondria are being studied to determine its mode of action. When the poison is added, all proteins and Q in the electron transport chain are in the reduced form, and ATP production stops. (Assume electron transport is continuously occurring.) This means that the poison could be inhibiting complex I.
Q1: Define ATP in your own words. Q2: How is ATP involved in anabolism and catabolism? (Hint: Review Figure 5.3.) Q3: Arsenic disrupts ATP production. Why would this characteristic cause it to be a potent poison?
