The main reason that cellular aerobic respiration needs to occur step by step instead of a single, big reaction is

A. cells don't have enough mitochondria to catalyze the larger, single reaction.
B. too much energy would be released as heat and destroy the cell.
C. cells don't store enough oxygen to absorb all the energy in one release.
D. cells produce the enzymes needed for cellular respiration very slowly.
E. glucose breaks down slowly, carbon by carbon, inside a cell.


B. too much energy would be released as heat and destroy the cell.
