Answer:
Generation of an action potential in the neuron.
Stimulation of Ca2+ entry into the neuron
Release of acetylcholine into the synapse
Depolarization of the muscle fiber membrane
Explanation:
The following events takes place in the vertebrate neuromuscular junction
a) Nerve Action Potential - Action potential reaches the axon terminal
b) Entry of calcium ion - The calcium ion reaches the axon terminal and enter into the presynaptic terminus after which the Synaptic vesicles fuse with the membrane of axon terminal
c) Releasing of Arch Quanta - Acetylcholine is released into synaptic cleft which then binds to the receptor sites on motor end plate
d) The Na+/K+ channels opens and Motor end plate becomes depolarized.
Menstruation does not occur if the D) egg is fertilized.
If you are pregnant, you don't menstruate.
To help work place with the system
Answer:
The correct answer is d. plasma membrane
Explanation:
Bacteria do not have membrane-enclosed organelle like mitochondria to generate ATP but even then it produces ATP because in bacterial plasma membrane acts as the machinery of ATP synthesis.
The ATP synthesis in bacteria is the same as eukaryotes. In prokaryotes, the plasma membrane consists of an electron transport system and NADH helps in building the proton gradient across the plasma membrane.
Then after the proton gradient is built in the plasma membrane the proton tends to come back into the cytoplasm through the ATP synthase complex which generates ATP from ADP and inorganic phosphate.
Therefore the correct answer is d. plasma membrane.
