Incomplete oxidation of glucose into pyruvic acid with several intermediate steps is known as:
Correct answer: B. Glycolysis
- A. T.C.A pathway
- B. Glycolysis
- C. Calvin pathway
- D. C4 pathway
Explanation
Glycolysis is the initial stage of cellular respiration that occurs in the cytoplasm of the cell. It involves the breakdown of one molecule of glucose into two molecules of pyruvic acid. Glycolysis is an anaerobic process and does not involve the complete oxidation of glucose; it is followed by the TCA cycle and oxidative phosphorylation in aerobic conditions.

About Bioenergetics
Cellular respiration explains how cells release energy from glucose through glycolysis, the link reaction, Krebs cycle and electron transport chain. It includes ATP production, substrate-level and oxidative phosphorylation, aerobic versus anaerobic respiration, and the roles of mitochondria, oxygen and fermentation in energy transfer.
