Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which type of Cellular Respiration occurs when oxygen is NOT present?
A
Fermentation
B
Anaerobic Respiration
C
Aerobic Respiration
D
Both Fermentation and Anaerobic Respiration
Explanation: 

Detailed explanation-1: -Anaerobic Respiration –Takes place in the absence of oxygen.

Detailed explanation-2: -Fermentation starts with glycolysis, but it does not involve the latter two stages of aerobic cellular respiration (the Krebs cycle and oxidative phosphorylation).

Detailed explanation-3: -Glycolysis: Glycolysis is a Metabolic Pathway that is common to both cellular respiration and fermentation. The first stage of respiration is glycolysis. When glucose is converted into pyruvate, then the process is referred to as glycolysis.

Detailed explanation-4: -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.

Detailed explanation-5: -Both of these methods are anaerobic (do not require oxygen) to achieve NAD+ regeneration and enable organisms to convert energy for their use in the absence of oxygen. During fermentation, only glycolysis occurs.
