in step 1 of glycolysis, glucose is phosphorylated to produce...
fructose-6-phosphate
g3p
phosphenol pyruvate
glucose-6-phosphate

Explanation:

In step 1 of glycolysis, the enzyme hexokinase (or glucokinase in the liver) catalyzes the phosphorylation of glucose using ATP. This reaction adds a phosphate group to glucose, resulting in the formation of glucose - 6 - phosphate. Fructose - 6 - phosphate is formed in a later step (step 2, isomerization of glucose - 6 - phosphate). G3P (glyceraldehyde - 3 - phosphate) is formed in the energy - investment phase but not in step 1. Phosphoenolpyruvate is a later intermediate in glycolysis, near the end of the pathway.

Answer:

D. glucose - 6 - phosphate
