Question

Which protein functions as a motor protein that applies the power stroke during muscle contraction? which protein functions as a motor protein that applies the power stroke during muscle contraction? a b c d?

Answer 1

Answer;

Myosin

Explanation;

The myosin head groups (C) hydrolyze ATP to power molecular movement along the actin subunits of the thin myofilaments.

Motor proteins are molecular motors that use ATP hydrolysis to move along cytoskeletal filaments within the cell.

These proteins are responsible for various functions within biological systems, such as controlling the sliding of filaments in muscle contraction (myosin) and also mediating intracellular transport along biopolymer filament tracks.
