Question

question 3 (1 point) if we want a muscle fiber to relax, which of the following should not happen? acetylcholinesterase digests acetylcholine myosin head detaches from components of actin amount of calcium ion increases in the sacroplasm tropomyosin covers active site on g - actin

Explanation:

An increase in calcium ions in the sarcoplasm triggers muscle contraction, not relaxation. Acetylcholinesterase digesting acetylcholine helps end muscle - contraction signals for relaxation. Myosin head detaching from actin components is part of muscle relaxation. Tropomyosin covering active sites on G - actin prevents myosin - actin interaction, which is related to relaxation.

Answer:

amount of calcium ion increases in the sacroplasm
