The Muscular System

Question 7 • Health Science Concepts A1 – EDGNTY-83861 26-27

Which of these is the energy-carrying particle that enables muscle contraction?

Answer
A
ATP
B
water
C
oxygen
D
sarcolemma

Explanation

ATP (adenosine triphosphate) carries and supplies usable energy for muscle contraction. Muscle fibers use energy released when ATP is broken down to power the interactions that produce contraction. Water and oxygen have important roles in the body, while the sarcolemma is the muscle cell’s membrane, not an energy-carrying particle.
