Explanation:
Answer:
Chemically gated Na+-K+ channels
Explanation:
The acetylcholine receptors are the receptors or ion channel proteins which are considered the transmembrane proteins. The acetylcholine receptors are of two types depending on the ligand which binds that is either nicotinic or either muscarinic receptors.
When the acetylcholine binds the receptor molecule, the ion channels open up and allows the passage of the sodium and potassium ios which depolarizes the membrane potential and generates the action potential in the neuron.
Thus, Chemically gated Na+-K+ channels is correct.
The answer is phospholipids. The phospholipids are a group of lipids that are main constituent of all cell membranes in which they can make lipid bilayers because of their amphiphilic feature. The arrangement of the phospholipids molecule primarily includes of two hydrophobic fatty acid tails and hydrophilic head consisting of phosphate group. The two constituents are linked by a glycerol molecule and phosphate class can be altered with organic molecules such as choline.
