Nicotinic receptors a. are found at neuroeffector junctions of the parasympathetic nervous system. b. respond to epinephrine. c.
Verizon [17]

Answer:

Option C, open chemically gated sodium ion channels.

Explanation:

The nicotinic receptors are present on the muscle cell membrane. These receptors belong to the class of cholinergic receptor which binds to the acetylcholine and opens the gated channel to allow transfusion of cation through it. These actions of the receptors are stimulated by the neurotransmitter. Nicotinic receptors are very fast at acting and hence are more prevalent at the neuromuscular junction.

Hence, option  C is correct

How does a selectively permeable membrane affect diffusion?
Mrrafil [7]

Answer:

- Only some molecules move from a higher concentration to a lower concentration.

Explanation:

Selective permeability of the membrane means that membrane regulates which molecules (ions, substances) and how much of them can pass through it. Permeabilty of the membrane is determinated by its structure (hydrophobic heads and hydrophilic tails, cholesterol), temperature

The simplest form of transport through membrane is diffusion, passive transport of the molecule down its concentration gradient 9from higher to lower concentration). Some molecules can move down their concentration gradients directly, some have to pass through membrane proteins in a process called facilitated diffusion while others require energy and use active transport.
