Glycolysis: The process by which glucose is broken down in cells to produce energy. It's like breaking down gasoline into its components so it can power an engine.
Insulin: A hormone that regulates the amount of glucose in our blood. Imagine insulin being like a traffic cop, directing where and when glucose should go into our body’s cells.
Cellular Respiration: The process by which cells use oxygen to break down glucose and create ATP (energy). It's akin to how an engine burns gas to move a car.
