Here's how it works:
* Carbohydrates are broken down: When you eat carbohydrates, your body breaks them down into glucose (a simple sugar).
* Glucose is used in cellular respiration: This process occurs in the cells and uses glucose as fuel.
* Energy is released: As glucose is broken down, energy is released.
* ATP is synthesized: This energy is used to attach a phosphate group to ADP (adenosine diphosphate), creating ATP.
ATP is the primary energy currency of cells. It is used to power various cellular processes, such as muscle contraction, nerve impulse transmission, and protein synthesis.
