Cytochromes occur in

Which final cytochrome in the respiratory chain donates electrons to oxygen?

During aerobic respiration,the total number of $ATP$ formed through oxidative phosphorylation / $ETS$ from one glucose molecule is . . . . . . .

Oxygen is an essential requirement for aerobic respiration, but it enters the respiratory process at the end. Discuss.

$A-$ $ATPase$ is a multienzyme complex containing two parts $F_0$ and $F_1$.
$R-$ The $F_1$ headpiece is a peripheral membrane protein complex and contains the site for synthesis of $ATP$ from $ADP$.

In cellular respiration,$O_2$ is used as a final electron acceptor of
