Multiple Choice
In cellular metabolism, what is the main function of glycolysis?
A
To convert glucose into pyruvate while producing a net yield of ATP and NADH
B
To oxidize acetyl-CoA to in the citric acid cycle while generating GTP
C
To convert pyruvate into acetyl-CoA while producing NADH and releasing
D
To generate ATP by transferring electrons from NADH to in oxidative phosphorylation
Verified step by step guidance1
Identify the primary substrate and product of glycolysis: glycolysis starts with glucose and ends with pyruvate.
Understand the energy yield of glycolysis: during the conversion of glucose to pyruvate, ATP and NADH molecules are produced.
Recognize the role of glycolysis in cellular metabolism: it provides energy and metabolic intermediates by breaking down glucose.
Distinguish glycolysis from other metabolic pathways mentioned, such as the citric acid cycle, pyruvate oxidation, and oxidative phosphorylation, which have different substrates, products, and functions.
Summarize that the main function of glycolysis is to convert glucose into pyruvate while producing a net gain of ATP and NADH, which are essential for cellular energy and further metabolic processes.
