Muscle Contractions Flashcards
1
Q
Describe how the role of acetylcholine results in muscle contractions
A
- Calcium is released
- Calcium binds to actin
- Myosin attaches to actin
- Muscles shorten
2
Q
Explain the role of ATP in muscle contraction
A
- ATP breaks down ADP and P- providing energy this enables myosin to pull/join actin filaments and form a cross bridge resulting in filaments sliding allowing the process to recycle
