To balance out negative charges on the interior of the membrane, voltage-gated sodium channels open, allowing sodium ions to enter the cell.
There are two factors that draw sodium ions (Na+) to the inside of neurons while they are at rest. The (Na+) ion is pushed into the cell down the concentration gradient by the high concentration of (Na+) outside the cell. Similar to how the positively charged (Na+) inside the neuron is drawn in by the electrostatic pressure caused by the negative charge inside.
Which of the four ion channel types are they? Ion channels that are voltage-gated, Linguistic-gated ion channels (also known as ionotropic receptors), ion channels with light-gated, Ion channels with mechanosensitivity, Nucleotide-gated ion channels that cycle, and Ion channels that are calcium-gated.

Answer:
Digestion is important for breaking down food into nutrients, which the body uses for energy, growth, and cell repair. Food and drink must be changed into smaller molecules of nutrients before the blood absorbs them and carries them to cells throughout the body. Protein must be broken down into amino acids. Starches break down into simple sugars. Fats break down into into fatty acids and glycerol.
