Question

a heart cell uses the energy in glucose to synthesize atp. structural support metabolism for energy energy storage protein synthesis

Explanation:

The heart cell is using glucose to make ATP which is related to energy - metabolism. Glucose is broken down in a series of metabolic reactions to release energy that is used to synthesize ATP. Structural support is mainly related to proteins like collagen and not directly to glucose - to - ATP synthesis. Energy storage is more about molecules like glycogen and fat. Protein synthesis is about making proteins from amino - acids and not about using glucose for energy.

Answer:

metabolism for energy
