Question

In the first step of glycolysis, what is glucose transformed into?

a) Fructose-6-phosphate
b) Pyruvate
c) Glucose-6-phosphate
d) Acetyl-CoA

Answer 1

In glycolysis, glucose is transformed into fructose-6-phosphate.

Step-by-step explanation:

Glycolysis is the first step of cellular respiration, which is the process by which cells convert glucose into energy in the form of ATP.

In the first step of glycolysis, glucose is transformed into fructose-6-phosphate. This conversion is catalyzed by the enzyme glucose-6-phosphate isomerase.

Fructose-6-phosphate is then further metabolized in subsequent steps of glycolysis to eventually produce pyruvate, which is the end product of glycolysis.
