What is a major obstacle in cellular respiration?
a)
It requires oxygen to be actively pumped against its concentration
gradient into cells
b)
It is an exergonic reaction, with much of the energy lost as heat,
which potentially might damage cells
c)
It is limited by the low amount of energy stored in a glucose
molecule
d)
It is an inefficient reaction and doesn't provide eukaryotic cells
with enough energy
