Definitions:

ATP

Adenosine Triphosphate, a molecule that stores and transports chemical energy within cells.

ADP

Adenosine Diphosphate, a compound involved in energy transfer within cells, produced through the breakdown of ATP (Adenosine Triphosphate).

Isotonic Solution

A solution that has the same osmotic pressure as the fluid in a cell, leading to no net movement of water into or out of the cell.

Red Blood Cells

The cells in the blood primarily responsible for carrying oxygen from the lungs to the rest of the body, using the protein hemoglobin.
