Question

The process of aerobic respiration is completed in two steps: _________ and __________.

• A. Glycolysis
• B. Kreb's cycle

Answer 1

Aerobic Respiration:

1. Aerobic respiration is the process by which oxidation of organic food occurs in the presence of oxygen.
2. Carbon dioxide and water are released as products of aerobic respiration.

Glycolysis:

1. Glycolysis is the process by which the breakdown of glucose takes place in the cytoplasm of the cell.
2. During the process of glycolysis, glucose is broken down into pyruvic acid molecules
3. It is denoted by the equation: Glucose ⟶ 2 Pyruvic acid

Krebs cycle:

1. Krebs cycle is also known as a citric acid cycle or TCA cycle.
2. During this cycle, 1 molecule of ATP, 1 FADH₂ and 3 NADH₂ along with carbon dioxide and water are produced by the complete degradation of one molecule of pyruvic acid in the mitochondrial matrix.

Final answer: The process of aerobic respiration is completed in two steps: Glycolysis and Krebs cycle.
