When two amino acid monomers are positioned so that the carboxyl group of one is adjacent to the amino group of the other, they can be joined through a dehydration reaction?

Answer;

-Peptide bond

Explanation;

-The amino acids are the building blocks of the proteins. The amino acids are joined to form a long chain of acids by amino and carboxyl and yields water. This long chain amino acids is the primary protein.

-A peptide bond is a chemical bond formed between two molecules when the carboxyl group of one molecule reacts with the amino group of the other molecule, releasing a molecule of water (H2O). This is a dehydration synthesis reaction; also known as a condensation reaction, and usually occurs between amino acids.

A.

Explanation:

Depolarization of a cell occurs when the membrane potential across the cell membrane rises above -70 mV which is the resting membrane potential in most neurons.

Depolarisation occurs when the voltage-gated channels open up and the Na2+ ions rush into the cell. To regain the membrane potential, then the Na2+ ions need to be pumped out of the cell. IF the membrane potential goes below -70 mV then the cell membrane can be referred to as hyperpolarised.
