Question

question 2 (1 point) how does the shape (form) of myosin allow it to work properly (function)? a myosin and actin work together to allow the muscle to contract and lengthen. b myosin is shaped like a braid, which allows actin hook on to it and pull the muscle during contraction. c myosin has to fit into a receptor of a cell so that muscles can grow properly. d myosin is shaped like a hook, which allows is to hook on to the actin protein and contract the muscle

Explanation:

Myosin has a hook-like head domain that binds to actin filaments. This shape enables myosin to form cross-bridges, pull on actin, and drive muscle contraction. Option a incorrectly frames their joint action, option b misstates myosin's shape, and option c describes an unrelated cell receptor interaction.

Answer:

d. Myosin is shaped like a hook, which allows is to hook on to the actin protein and contract the muscle.
