Cross Bridge Detachment is Caused by ________ Binding to the Myosin

Question

Cross bridge detachment is caused by ________ binding to the myosin head.
A) ATP
B) calcium
C) magnesium
D) acetylcholine
E) acetylcholinesterase

Accepted Answer

Cross bridge detachment is caused by ATP binding to the myosin head, which causes it to release from actin filaments. Calcium triggers cross bridge formation, but it does not directly cause detachment. Magnesium and acetylcholine are not involved in the process of cross bridge detachment. Acetylcholinesterase is an enzyme that breaks down acetylcholine and is not directly involved in muscle contraction.
