Chapter 18, Problem 106SCQ

(a)

Interpretation Introduction

Interpretation:

The ${\text{Δ}}_{\text{r}}{\text{G}}^{\text{o}}$ for given reaction should be calculated.

Concept introduction:

The cells in our body requires energy to do its function. This energy is provided by the breakdown of glucose to pyruvate. The process is known as glycolysis. Pyruvate generated gives ${\text{CO}}_{\text{2}}$ and ${\text{H}}_{\text{2}}\text{O}$ in presence of oxygen. However, if the oxygen supply is limited then lactate formation takes place. The reaction is written as,

    $\text{pyruvate}+\text{NADH}+{\text{H}}^{+}\stackrel{\begin{array}{l}\text{ lactate}\\ \text{dehydrogenase}\end{array}}{\to }\text{lactate}+{\text{NAD}}^{+}$
