The answer would be:

<em><u>D. Insulin</u></em>

Insulin is a chemical messenger that is responsible for the regulation of blood glucose levels. It is manufactured in the pancreas and secreted by the beta cells as a response to glucose. When glucose levels in blood plasma increase, insulin is secreted to stimulate glucose uptake.

MAIN IDEA: Glycolysis is needed for cellular respiration.
FrozenT [24]

Answer:

Glycolysis is an organic catabolic process where small molecules are originated by splitting of a larger molecule.

Explanation:

A Catabolic reaction is a way by which we obtain any break down of a big organic matter into small parts.

Glycolysis is a great example of any catabolic reaction. Let see this process by the equation-

C6H12O6 (glucose) + 2 NAD+ + 2 ADP + 2 P -----> 2 pyruvic acid, (CH3(C=O) COOH + 2 ATP (energy) + 2 NADH + 2 H+

From the upper equation, we can see that it fracture the Glucose (energy carrier) and generates pyruvic acid (energy supplier) and ATP (energy) with some other byproducts, so we can easily say the primary function of Glycolysis is to produce energy by splitting one energy-carrying molecule.
