Question

a carbohydrate that enters glycolysis directly
sucrose
acetic acid
nad+
starch
nadh
glucose
atp
pyruvic acid

Explanation:

Glycolysis is the metabolic pathway that converts glucose into pyruvate. Glucose is a carbohydrate and is the starting - molecule for glycolysis. Sucrose needs to be hydrolyzed first, starch needs to be broken down into glucose monomers first. Acetic acid is not a carbohydrate. NAD⁺ and NADH are co - enzymes, not carbohydrates. ATP is an energy - carrying molecule, not a carbohydrate. Pyruvic acid is the end - product of glycolysis, not the starting carbohydrate.

Answer:

glucose
