Question

Both aerobic and anaerobic respiration yield a net gain of ATP molecules to be used as energy for living things. The processes of _________ would yield the highest number of ATP.

Answer 1

A)glycolysis
B)fermentation
C)oxidative phosphorylation
D)the Krebs Cycle

Answer 2

Answer: The correct answer for the fill in the blank is Aerobic respiration.

Aerobic respiration is a process of respiration in which cell utilizes glucose and oxygen molecule in order to generate large amount of cellular energy that can be further used for cellular work. It is a highly energy efficient process as it produces upto 38 molecules of ATP.

On the other hand, anaerobic respiration ( common in micro organisms) generates cellular energy ( ATP) using only glucose that is in absence of oxygen. It generates only 2 ATP molecules and thus very less efficient process.
