1. Action potential reaches the axon terminal and depolarizes it.

2. Depolarization opens voltage-gated calcium channels, enabling influx of Ca into the neuron.

3. Calcium binds to specialized proteins on vesicles (containing pre-made acetylcholine) and triggers them to fuse with the neuron membrane at the synapse.

4. Exocytosis of acetylcholine into the synaptic cleft occurs.

5. Acetylcholine diffuses across the synapse and binds to nicotinic receptors on the end plate of the myocyte.

6. Activated nicotinic receptors, themselves ion channels, cause cation influx into the myocyte and generate an end plate potential. This eventually gives rise to the full depolarization within the myocyte that enables contraction.

Most of the atp supplies for a skeletal muscle undergoing one hour of sustained exercise come from _____.
ioda

The question is incomplete as it does not have the options which are:

A) creatine phosphate.

B) glycolysis.

C) substrate phosphorylation.

D) oxidative phosphorylation.

E) de novo synthesis.

Answer:

D) oxidative phosphorylation.

Explanation:

The ATP is the energy molecule which provides energy to every metabolic process in the organism.

The ATP in humans is produced by a process called cellular respiration where the last phase of the process called electron transport chain produces the highest amount of protein. The electron transport chain is also known as the oxidative phosphorylation as the oxygen is gained and electrons are lost during the phase.

Thus, D) oxidative phosphorylation is correct.
