Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of respiration is most efficient?
A
Aerobic
B
Anaerobic
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -The ATP yielded in aerobic respiration is about 38 molecules by complete oxidation of a single glucose molecule. On the other hand, anaerobic respiration produces only 2 ATP per glucose molecule. Thus, the most efficient form of respiration is aerobic respiration.

Detailed explanation-2: -Aerobic respiration is much more efficient than fermentation. One molecule of glucose can generate up to 38 molecules of ATP if aerobic respiration is used.

Detailed explanation-3: -Efficiency =38×8.1×100686=45% Q. Why is aerobic respiration more efficient than anaerobic respiration?
