Which is the primary function of glucose molecules? a. to make up the structure of cell membranes be. b. to act as a catalyst for chemical reactions c. to encode genetic information d. to provide energy for cell activities

The primary function of glucose molecules is to provide energy for cell activities.

Explanation:

Glucose can best be described as carbohydrate which serves best as a primary fuel. Our body cells carry out a wide number of metabolic as well as biological functions.  Glucose serves as the main energy derivation molecule for the accomplishment of these biological and metabolic functions. Every cell present in the body acquires the capability of using glucose as energy molecule.

Glucose is broken down by complex biological reactions into ATP which is the energy source for many cellular activities.
