Answer:
Termites have cellulose-digesting protists in their guts.
Explanation:
Termites are able to access nutrients contained in cellulose due to their mutualistic association with some cellulose-digesting protists such as <em>Trichonympha</em> and M<em>ixotricha</em>. The protists produce cellulase in addition to other glycolytic enzymes that work together to convert cellulose to malate.
The malate produced is further metabolized to produce
, hydrogen, acetate and energy in the form of ATP.
The protists get sheltered in the termite's gut in return.
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.
