Question

Glycolysis is a metabolic pathway that converts glucose into pyruvate and is observed in each of the three domains. The hexokinase family of enzymes is required during glycolysis to phosphorylate six-carbon sugars. Researchers designed a general hexokinase inhibitor that is effective in the neurons of rats.True / False.

Answer 1

Answer: True

Explanation:

Glycol= sugar

Lysis = break

Glycolysis is the first of the three stages of cellular respiration.

In this step, 6-carbon glucose is broken apart into two 3-carbon molecules called pyruvate.

Now this occurs in three stages

• The first stage being that in which the conversion of glucose into fructose 1, 6- bisphosphate, consists of three steps: a phosphorylation, an isomerization, and a second phosphorylation reaction.

In glycolysis, hexokinase is an enzyme whose substrate is glucose and its most important by-product is glucose 6-phosphate.

This enzyme involves in phosphorylation of a six-carbon sugar, a hexose, to make a hexose phosphate in glycolysis.
