Question

Which of the following is NOT necessary for muscle contraction to occur? A. Production and presence of adenosine triphosphate (ATP) B .Acetylcholine to bind to the sarcolemma receptors C.Nerve impulse (action potential) D. Sodium ions to bind to the thin filament 09

Answer 1

Muscle contraction requires the production and presence of ATP, acetylcholine binding to sarcolemma receptors, a nerve impulse, and sodium ions to bind to the thin filament.

Step-by-step explanation:

Muscle contraction requires several factors to occur, including:

Therefore, the correct answer is D. Sodium ions are necessary for muscle contraction to occur.
