Why is it not to the cell's advantage to simply make more NAD+ in the conversion of glucose into 2 molecules of lactate, while the NADH generated earlier in the pathway is oxidized?
a) More NAD+ production would disrupt cellular redox balance.
b) NAD+ production is energetically unfavorable.
c) The cell lacks the necessary enzymes to produce NAD+.
d) NAD+ is not involved in cellular metabolism.
