(a)
To calculate: The ΔG value at pH 7.0 for the LDH-catalyzed reduction of pyruvate under the given condition.
Concept introduction: Pyruvate is known as the end product of glycolysis that continues in two different conditions. In aerobic process, it undergoes aerobic respiration; whereas in anaerobic process, it undergoes fermentation. There are two types of fermentation that occurs by pyruvate, one is the lactic acid fermentation and the other one is the alcoholic fermentation.
(b)
To explain: The ΔG value at pH 7.0 for the LDH-catalyzed reduction of pyruvate under the given condition.
Concept introduction: Pyruvate is known as the end product of glycolysis that continues in two different states. In aerobic process, it undergoes aerobic respiration; whereas in anaerobic process, it undergoes fermentation. There are two types of fermentation that occurs by pyruvate, one is the lactic acid fermentation and the other one is the alcoholic fermentation.
(c)

Concept introduction: Pyruvate is known as the end product of glycolysis that continues in two different states. In aerobic process, it undergoes aerobic respiration; whereas in anaerobic process, it undergoes fermentation. There are two types of fermentation that occurs by pyruvate, one is the lactic acid fermentation and the other one is the alcoholic fermentation.
(d)
To explain: The effect of concentration ratios in part a-c on the direction of the reaction.
