|
|
Glycolysis is the final step in aerobic respiration.
|
|
|
Glycolysis produces a net of 1 ATP, 1 NADH, and 2 pyruvate.
|
|
|
Glycolysis can occur without the presence of oxygen.
|
|
|
Glycolysis takes place in the mitochondria of a cell.

Detailed explanation-1: -Glycolysis can occur without the presence of oxygen. The process of glycolysis can occur with or without oxygen. In fact, many anaerobic organisms (organisms that do not use oxygen) use glycolysis as a step in their respiration processes, Which of the following statements best is true of the Krebs cycle?
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: -Glycolysis results in complete oxidation of glucose into pyruvic acid.
Detailed explanation-4: -Anaerobic respiration proceeds in the absence of oxygen.
