At which step, glycolysis reaches the break-even point where 2
molecules of ATP consumed, and 2 new molecules synthesized?

Sucrose is converted into glucose and fructose by the enzyme:

1. Maltase
2. Zymase
3. Isomerase
4. Invertase

During glycolysis, when glucose is catabolized to pyruvate, most of the energy of glucose is 

ATP production during cellular respiration is controlled by allosteric inhibition. The control is the allosteric inhibition by ATP and citric acid of the enzyme that facilitates the formation of:

The three boxes in this diagram represent the three major biosynthetic pathways in

aerobic respiration. Arrow represent net reactants or products

Arrows numbered 4, 8, 12 can all be 

1. NADH

2. ATP

3. H₂O

4. FAD⁺ or FADH₂

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
