Mention two acids found in the human body and their functions.

The stomach contains cells that produce hydrochloric acid, a component of the gastric juice that helps humans digest food. This is one of the most important acids in the human body, as it helps break food into smaller pieces that are easy to digest. Hydrochloric acid also helps the stomach maintain its acidic environment.

During strenuous exercise, the amount of oxygen available to your muscles decreases. This prompts the muscle cells to produce lactic acid as a source of fuel for the mitochondria, which produce energy. As the mitochondria exhaust the available supply of lactic acid, the muscles are able to work longer and harder.

Hydrochloric acid: in the stomach lowers the pH to the ideal environment for enzymes to digest proteins into units that the body can use. The acidic environment creates an antibacterial environment that will protect the body from disease.

Amino acids:  build proteins, and proteins are life-sustaining macronutrients. Your body can also use amino acids for energy when you lack carbs and fats.
