Front

What is the primary function of Actin in muscle contraction?

Back

Actin provides the structural framework for muscle contraction.

Front

What role does Myosin play in muscle contraction?

Back

Myosin interacts with Actin to facilitate muscle contraction.

Front

What is ATP and why is it important for muscles?

Back

ATP (Adenosine Triphosphate) is the energy currency of the cell, crucial for muscle contraction.
