GLYCOLYSIS

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following is not true of glycolysis?
A
it is the first stage of cellular respiration
B
it occurs in the cytoplasm
C
it only occurs if oxygen is present
D
means the breakdown of sugar
Explanation: 

Detailed explanation-1: -Answer and Explanation: The statement that is not true regarding glycolysis is c. Glycolysis can occur in the cytoplasm of the cell or the mitochondria. Glycolysis only occurs in the cytosol or cytoplasm of the cells and not in the mitochondria.

Detailed explanation-2: -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. However, if oxygen is not present, some organisms can undergo fermentation to continually produce ATP.

Detailed explanation-3: -Review: In the process of glycolysis, a net profit of two ATP was produced, two NAD+ were reduced to two NADH + H+, and glucose was split into two pyruvate molecules. When oxygen is not present, pyruvate will undergo a process called fermentation.
