Cellular Respiration and Energy Production: Understanding the Process
Cellular respiration is a vital process that occurs within cells to generate energy for various cellular activities. It involves the breakdown of glucose and other organic molecules to produce ATP (adenosine triphosphate), which serves as the primary energy currency of the cell. In this article, we will explore the process of cellular respiration, specifically focusing on the energy-releasing process that occurs when two moles of glucose are oxidized completely for bacterial motility.
What is Cellular Respiration?
Cellular respiration is a metabolic process that involves the breakdown of glucose and other organic molecules to produce energy in the form of ATP. It is a complex process that occurs in three stages: glycolysis, the citric acid cycle, and oxidative phosphorylation. During these stages, glucose is converted into carbon dioxide and water, releasing energy in the form of ATP.
The Energy-Releasing Process: Catabolism
Catabolism is the process of breaking down complex molecules into simpler ones, releasing energy in the process. In the context of cellular respiration, catabolism refers to the breakdown of glucose and other organic molecules to produce ATP. This process involves the oxidation of glucose, resulting in the release of energy that is captured and stored in the form of ATP.
Anabolism: The Building-Up Process
Anabolism is the process of building up complex molecules from simpler ones, requiring energy in the process. In contrast to catabolism, anabolism involves the synthesis of new molecules from existing ones, often requiring energy in the form of ATP.
Amphibolic Pathways: A Combination of Catabolism and Anabolism
Amphibolic pathways refer to metabolic processes that involve both catabolism and anabolism. In the context of cellular respiration, amphibolic pathways involve the breakdown of glucose and other organic molecules to produce ATP, while also synthesizing new molecules from the products of catabolism.
ATP: The Energy Currency of the Cell
ATP (adenosine triphosphate) is the primary energy currency of the cell. It is a molecule that stores energy in the form of phosphate bonds, which can be broken down to release energy. ATP is produced during cellular respiration and is used to power various cellular activities, including muscle contraction, protein synthesis, and membrane transport.
In conclusion, the energy-releasing process that occurs when two moles of glucose are oxidized completely for bacterial motility is known as catabolism. Catabolism is the process of breaking down complex molecules into simpler ones, releasing energy in the process. While anabolism and amphibolic pathways also play important roles in cellular metabolism, catabolism is the primary process involved in the breakdown of glucose and other organic molecules to produce ATP.
The correct answer is A. Catabolism.

Cellular Respiration and Energy Production: Understanding the Process
Q: What is cellular respiration?
A: Cellular respiration is a vital process that occurs within cells to generate energy for various cellular activities. It involves the breakdown of glucose and other organic molecules to produce ATP (adenosine triphosphate), which serves as the primary energy currency of the cell.
Q: What are the three stages of cellular respiration?
A: The three stages of cellular respiration are:
- Glycolysis: The breakdown of glucose into pyruvate, producing a small amount of ATP and NADH.
- The citric acid cycle: The breakdown of pyruvate into acetyl-CoA, producing a large amount of ATP, NADH, and FADH2.
- Oxidative phosphorylation: The transfer of electrons from NADH and FADH2 to oxygen, producing a large amount of ATP.
Q: What is the energy-releasing process in cellular respiration?
A: The energy-releasing process in cellular respiration is known as catabolism. Catabolism is the process of breaking down complex molecules into simpler ones, releasing energy in the process.
Q: What is anabolism?
A: Anabolism is the process of building up complex molecules from simpler ones, requiring energy in the process. In contrast to catabolism, anabolism involves the synthesis of new molecules from existing ones, often requiring energy in the form of ATP.
Q: What is amphibolic metabolism?
A: Amphibolic metabolism refers to metabolic processes that involve both catabolism and anabolism.
