Question

multiple choice question

when muscles contract, what is released?

o oils
o cartilage
o heat
o sphincters

Explanation:

Identify the physiological process

Using the Muscle Contraction knowledge point
During cellular respiration and the cross-bridge cycle, ATP is hydrolyzed to power movement, releasing energy.

Determine the byproduct of contraction

Using the Muscle Heat Production knowledge point
A significant portion of the energy released during ATP hydrolysis is lost as thermal energy, generating body heat.

Answer:

• Oils
• Cartilage
• Heat (Correct answer)
• Sphincters
