Q1

Below are standard reduction potentials of components in carbohydrate metabolism

$\tiny \large \small \small \small \small NAD^++H^++2e^- \rightarrow NADH$ $\tiny \tiny \small \small \Delta V=-.32V$

$$\frac{1}{2}$O_2+2H^++2e^- \rightarrow H_2O$ $\tiny \small \small \Delta V=.82V$

$NADH+ H^++\frac{1}{2}$O_2 \rightarrow NAD^++H_2O$

What is the free energy change for this reaction?

$\Delta G= -nF\Delta V$
