What is the name of neurotransmitter involve in neuromuscular junction.

What is the NAME of the potential generated at motor end plate / sarcolemma, after the membrane depolarised?

If threshold potential is reached, action potentials will be generated along the sarcolemma. What would happen next?

ARRANGE: A) Ca2+ will diffuse out of the sarcoplasmic reticulum to sarcoplasm. B) The voltage – gated channel Ca2+ will open. C) Action potential spread down the T— tubules to sarcoplasmic reticulum.

Which of these molecules are important for muscles to contract?

__ binds to __ complex (on actin filament), causing troponin to change its conformation. __ will be pushed away, exposing __ binding site on __. Write the answers using SPACE ONLY. No need comma.

Initially, __ head is in __energy configuration. An __ will bind to the myosin head, which is also an __ enzyme. The __ will be hydrolyzed to __ + __. The myosin head is in __ energy configuration.

What is the term called, when myosin is bind to the actin?

The high-energy myosin will then bind to the exposed __ binding site on actin, forming __. Next, __+ Pi will be removed from myosin. Myosin will return to __ energy configuration. Power __ occurs.

After power stroke occurs, __ is pulled to the __ of __. Muscle is __. The next __ will bind to the myosin head, causing the myosin head to __ from actin. Cycle repeats.
