Some human cells, such as nerve cells, are restricted to aerobic respiration to recycle NADH and FADH2. If these cells are deprived of oxygen, then . ATP production would continue because the cell would perform fermentation oxidative phosphorylation would come to a halt because there wouldn't be any oxygen to "pull" the electrons down the transport chain glycolysis could still continue indefinitely proton gradient formation would continue, but ATP synthase function would stop

Some human cells, such as nerve cells, are restricted to aerobic respiration to recycle NADH and FADH2. If these cells are deprived of oxygen, then oxidative phosphorylation would come to a halt because there wouldn't be any oxygen to pull the electrons down the transport chain.

Explanation:

Aerobic cells like human nerve cells can only perform oxidative phosphorylation (and, therefore, ATP production) when in presence of oxygen, otherwise the process is stopped.

Fermentation is an anaerobic process that can only be performed by yeast cells, bacteria, and muscle cells in animals, allowing glucose to be metabolized even when there's no oxygen in the environment.

the corpus luteum secretes estrogens and progesterone. the latter hormone causes changes in the uterus that make it more suitable for implantation of the fertilized ovum and the nourishment of the embryo. if the egg is not fertilized, the corpus luteum becomes inactive after 10–14 days, and menstruation occurs.

i hope this : )
