5 Multiple Choice Questions
- ________ ____________ use ATP; myosin heads bind/bond to actin, swivel, and release ADP, ADP re-cocks and releases it; thin filaments are pulled toward center of sarcomere.
- Muscle AP traveling along the ______ _______ opens the Ca2+ gates and
- This filament has an ATP and actin binding site.
- When a nerve impulse reaches the end of an axon, acetylcholine is released into the _________ _________.
- Ca2+ ____ ______ _______Ca2+ release channels in SR close and Ca2+ _____ _____ _____ use ATP to restore low levels of calcium ions in sarcoplasm.
5 True/False Questions
Ca → This process of bond, swivel, release ADP, ATP recocks and releases it. (over and over) as long as ____ gates are open.
muscle action potential (AP) → Ca2+ ____ ______ _______Ca2+ release channels in SR close and Ca2+ _____ _____ _____ use ATP to restore low levels of calcium ions in sarcoplasm.
sarcoplasmic reticulum → Then the nerve impulse dips into the transverse tubules, coming in contact with the Ca gates on the ________.
Actin → This filament has an ATP and actin binding site.
sarcoplasmic reticulum (SR); sarcoplasm. → The Ca gates close, the ongoing active transport ATP generated Ca pumps push all the Ca back into the _______ _______, including that which was bonded to the troponin.
