Question

Cellular respiration involves:

• A. Only Glycolysis
• B. Only Krebs Cycle
• C. Glycolysis, Krebs Cycle and Electron Transport Chain only
• D. Krebs Cycle and Electron Transport Chain only

Answer 1

The correct option is C

Glycolysis, Krebs Cycle and Electron Transport Chain only

Cellular respiration involves following three processes:
1. Glycolysis - It is the process in which Glucose (a 6-carbon compound) is converted into Pyruvic acid (3-carbon compound).
2. Krebs Cycle - It is the process in which Pyruvic acid undergoes a series of reactions by which most living cells produce energy molecules. It is an aerobic process.
3. Electron Transport Chain - It is a process in which ATP is produced using the proton gradient created across a membrane.
