Which of the following describes 'glycolysis'?

Which of the following describes 'glycolysis'?

• A. The breakdown of protein into amino acids
• B. The breakdown of muscle into protein
• C. The breakdown of fat into fatty acids
• D. The breakdown of carbohydrates into pyruvic acid

Answer: (D)

Glycolysis is a metabolic pathway that involves the breakdown of glucose, which is a type of carbohydrate, into pyruvic acid. This process occurs in the cytoplasm of the cell and is the first step in cellular respiration, providing energy for the body. During glycolysis, glucose is converted through a series of enzymatic reactions, resulting in the production of energy in the form of ATP, as well as NADH, a crucial electron carrier. The significance of glycolysis lies in its ability to generate energy quickly without the need for oxygen, making it an anaerobic pathway. This is particularly important during high-intensity exercise, where the demand for energy exceeds the oxygen supply available for aerobic respiration. Glycolysis distinctly focuses on carbohydrates, differentiating it from other metabolic pathways that involve proteins and fats. Thus, the correct description of glycolysis is its role in converting carbohydrates into pyruvic acid, highlighting its importance in energy production and metabolic processes within the body.
