Answer:
a). 2.3
b). 1.5
Explanation:
The P/O ratio stands for the[tex]\text{ phosphate / oxygen ratio}[/tex] in the cells. The P/O ratio is defined as the [tex]\text{amount of}[/tex] [tex]ATP[/tex] which is [tex]\text{produced from the movement}[/tex] of the two electrons by a defined electron transport chain and it is terminated by the reduction in the oxygen atom.
The P/O ratio of NADH in mitochondria [tex]10/(3.3 + 1) = 10/4.3 \approx 2.3[/tex]
The estimated P/O ratio for [tex]$FADH_2$[/tex] = 1.5
