Which class of molecules are made up of amino acids, aid in the regulation of water balance, help maintain blood neutrality, and are responsible for repairing
body cells?
O Fats
B Vitamins
O Iron
O Proteins



Answer :

The class of molecules that are made up of amino acids, aid in the regulation of water balance, help maintain blood neutrality, and are responsible for repairing body cells are proteins. Here's why:

1. Amino Acids: Proteins are made up of amino acids, which are the building blocks of these molecules. Different combinations and sequences of amino acids create a vast array of proteins with various functions in the body.

2. Regulation of Water Balance: Proteins play a crucial role in maintaining water balance within cells and tissues. For example, certain proteins act as channels or pumps that help regulate the movement of water and ions across cell membranes.

3. Maintaining Blood Neutrality: Proteins help regulate the pH balance of blood by acting as buffers. They can accept or donate protons to help keep the blood at a constant and appropriate pH level, which is essential for various metabolic processes to function properly.

4. Repairing Body Cells: Proteins are involved in the repair and maintenance of body tissues. For instance, when cells are damaged or need to be replaced, specific proteins are responsible for carrying out repair processes and ensuring the proper functioning of the body's cells.

In summary, proteins are the class of molecules that fulfill the functions described in the question by utilizing the diversity of amino acids to perform essential roles in the body, including water balance regulation, blood neutrality maintenance, and cell repair.
