An action potential causes the release of neurotransmitters by:________.

seraphim [82]

Answer:

b) opening calcium pores in the membrane

Explanation:

The opening of calcium ions channels facilitates the migration of vesicles containing neurotransmitters in the pre-synaptic neurons to the tip of the post-synaptic membrane. at the neuromuscular junction These neurotransmitters can either be cholinergic or non-chorlinergic. At the tip of the pre-synaptic membranes the vesicles empty their neurotransmitter contents into the synapse.

The neurotransmitters, diffuse through the neuromuscular junction to bind with the receptors on the post-synaptic membrane on the post-synaptic neuron. This stimulates opening of ligand gated sodium ions, and sodium ions diffuse into the post-synaptic neuronal membrane, to cause depolarization. if the stimulus is up to the threshold levels it generate action potential.

Therefore , more calcium ions channels opening produces; more diffusion of neurotransmitters;leading to opening of more sodium channels for depolarization; and IPSP or EPSP generation.

What happens when removing and organism from a food chain?

kondor19780726 [428]

Answer:

It depends on whether or not the organism is a producer or a predator. If the organism removed is a producer, every other organism that relies on said producer for food will not be able to survive. If the organism removed is a predator, the organisms that said predator eats will flourish, diminishing the natural resources in the ecosystem and inevitably starving the population of the ecosystem.
