Pyruvate dehydrogenase activity during aerobic respiration requires:
| 1. | Calcium | 2. | Iron |
| 3. | Cobalt | 4. | Magnesium |
How many ATP molecules are produced by aerobic oxidation of one molecule of glucose?
| 1. | 2 | 2. | 4 |
| 3. | 38 | 4. | 34 |
How many ATP molecules could maximally be generated from one molecule of glucose, if the complete oxidation of one mole of glucose to and yields 686 kcal and the useful chemical energy available in the high energy phosphate bond of one mole of ATP is 12 Kcal?
| 1. | Two | 2. | Thirty |
| 3. | Fifty-seven | 4. | One |
Let us say there are 30 NADH and 12 in a mitochondrion. What is the maximum number of ATP generated if all dinucleotides are used in chemiosmosis?
| 1. | 42 | 2. | 84 |
