Explanation:
The heart contains cardiac autorhythmic muscle cells, which are specialized cells that generate their own action potential without the need to receive it from nerve cells. These self-stimulated or self-excitable cells work together and function as the heart's natural pacemaker, which initiates an electric potential at a constant rate, and this potential travels through the heart triggering its contraction in an organized manner called the cardiac cycle.
These autorhythmic cells are found in the SA (sinoatrial) node in the right atrium of the heart, the AV (atrioventricular) node in between the atria and the ventricles, and in the fibers that connect these two nodes with each other and with the rest of the heart. All these structure working together is what's called the heart's electrical system.

Answer:
What amino acids do is aid growth, cell replacement, and cell and tissue repair.
Explanation:
Amino acids are the units that make up the structure of proteins, necessary for the structure and function of living beings.
Due to the structural function of proteins —capable of forming tissues such as muscle and collagen that are present throughout the body— it can be said that <u>amino acids contribute to growth and development. In addition, amino acids and proteins can assist in cell renewal and repair of cells and tissues</u>.
The other options do not correspond to functions of the amino acids:
- <u><em>Help the body use certain vitamins and create cell energy </em></u><em>is a function of the lipids.
</em>
- <u><em>Provide energy and help cells get energy from other nutrients</em></u><em> is a function of carbohydrates.
</em>
- <u><em>Turn carbohydrates into proteins, fats, and fatty acids</em></u><em> is not a amino acid function.</em>
