Answer:
The correct statements are a, b and d. The incorrect statements are c and e.
Explanation:
Substrate level phosphorylation signifies the generation of ATP from ADP and a phosphorylated intermediate. On the other hand, in oxidative phosphorylation, the formation of ATP takes place from ADP and Pi, that is, an inorganic phosphate.
In substrate-level phosphorylation an enzyme is needed for the reaction to take place. In the process, a dissociation of bond takes place between an organic molecule and a phosphate prior to the formation of ATP. In this, one of the substrates is a molecule obtained from the dissociation of glucose.
In substrate-level phosphorylation, the enzyme taking part in the synthesis of ATP is not required to get attached to the membrane to generate ATP. The phosphate group, which is added to ADP to produce ATP does not come from free inorganic phosphate ions.

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.
