Difficulty Level:


How many ATP molecules could maximally be generated from one molecule of glucose, if

the complete oxidation of one mole of glucose to CO2 and H2O 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

Difficulty Level:


The TCA cycle is considered as an aerobic pathway because

1. all enzymes of the cycle use molecular oxygen

2. some enzymes of the cycle require molecular oxygen

3. molecular oxygen is essential to reoxidise the coenzymes reduced during operation of

the cycle.

4. in absence of oxygen, the enzymes of TCA cycle are denatured.
