Question

which of the following incorrectly describes the role of atp in skeletal muscle? group of answer choices atp drives the na/k pumps which maintain proper distributions of na and k ions atp binding to myosin breaks the acto-myosin cross bridge atp powers the reuptake of calcium back into the sr atp binds to actin to make the power stroke happen atp is hydrolyzed to re-energize the cross bridge by myosin atpase

Answer 1

Answer:D

Explanation:atp binds to actin to make the power stroke happen is incorrect as ATP binds with myosin to provide the energy required for the cross bridge

ATP also has a rule in the sodium potassium pump which exchanges 3 Na+ out with 2 K+ to maintain the RMP of skeletal muscle which is -90mv And also ATP has an important role in the reuptake of ca++ back to SR.
