The overall goal of glycolysis, the Krebs cycle, and the electron transport system is the formation of:
Correct answer: D. ATP in small stepwise units
- A. ATP in one large oxidation reaction
- B. Sugars
- C. Nucleic acids
- D. ATP in small stepwise units
Explanation
The overall purpose of these metabolic pathways is to gradually extract energy from glucose and use it to produce ATP through a series of small stepwise reactions. Glycolysis, the Krebs cycle, and the electron transport system work together to efficiently harvest energy and convert it into ATP.

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.
