Which process least amount of ATP in cells?
|
|
Glycolysis
|
|
|
Citric Acid cycle
|
|
|
Lactic acid Fermentation
|
|
|
Pyruvate Oxidation
|
Explanation:
Detailed explanation-1: -Glycolysis (see “Glycolysis” concept) is an anaerobic process-it does not need oxygen to proceed. This process produces a minimal amount of ATP.
Detailed explanation-2: -Answer and Explanation: Glycolysis is the break down of a molecule of glucose into 2 pyruvate molecules.
Detailed explanation-3: -Without oxygen, some human cells must use fermentation to produce ATP, and this process produces only two molecules of ATP per molecule of glucose. Although fermentation produces less ATP, it has the advantage of doing so very quickly.
