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.
That is true, species can breed within
Answer:
False
Explanation:
because internal fertilisation occurs in most bony fish, many reptiles, some cartilaginous fish, most amphibians, two mammals, and all birds. Reptiles and insects produce leathery eggs, while birds and turtles produce eggs with high concentrations of calcium carbonate in the shell, making them hard.
The answer is; Early steps consume energy from ATP, and later steps store an increased amount of energy in ATP and NADH
In the initial stage (energy consuming), 2 ATPs and consumed to convert glucose to the high energy fructose-1,6 biphosphate. The fructose-1,6 biphosphate is later split into 2 glyceraldehyde-3-phosphate (G3P). In the energy-releasing phase, each G3P is used to generate 2 ATPs and an NADH are released. Therefore, there is a net positive energy of 2 ATPs and 2 NADHs.
