Which of the Following "Slide" in the Sliding Filament Hypothesis

Question

Which of the following "slide" in the sliding filament hypothesis?
A) Calcium and ATP
B) Sarcoplasm and T tubules
C) Actin and myosin
D) Epimysium and perimysium

Accepted Answer

The actin and myosin filaments slide past each other during muscle contraction, which is the main concept of the sliding filament hypothesis. Calcium and ATP play important roles in muscle contraction, but they do not slide past each other. Sarcoplasm and T tubules are structures within muscle cells but do not play a direct role in filament sliding. Epimysium and perimysium are connective tissue layers that surround muscle but do not contribute to the sliding filament hypothesis.
