Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which describes the difference between aerobic and anaerobic cellular respiration?
A
anaerobic requires oxygen, while aerobic does not
B
aerobic requires oxygen, anaerobic does not
C
anaerobic respiration is never found in animals
D
aerobic respiraiton is only found in animals
Explanation: 

Detailed explanation-1: -There are two types of Respiration: Aerobic Respiration-Takes place in the presence of oxygen. Anaerobic Respiration –Takes place in the absence of oxygen.

Detailed explanation-2: -Anaerobic respiration is a normal part of cellular respiration. Glycolysis, which is the first step in all types of cellular respiration is anaerobic and does not require oxygen. If oxygen is present, the pathway will continue on to the Krebs cycle and oxidative phosphorylation.

Detailed explanation-3: -There are two types of cellular respiration: aerobic and anaerobic. One occurs in the presence of oxygen (aerobic), and one occurs in the absence of oxygen (anaerobic). Both begin with glycolysis-the splitting of glucose. Glycolysis is an anaerobic process-it does not need oxygen to proceed.

Detailed explanation-4: -which does not describe a key difference between aerobic and anaerobic respiration? aerobic takes place in the presence of oxygen, anaerobic does not.

Detailed explanation-5: -Cellular respiration always begins with glycolysis, which can occur either in the absence or presence of oxygen. Cellular respiration that proceeds in the absence of oxygen is anaerobic respiration. Cellular respiration that proceeds in the presence of oxygen is aerobic respiration.
