Front

What are carbohydrates?

Back

Carbohydrates are macromolecules made up of sugar molecules, serving as a primary energy source for living organisms.

Front

What is the function of ATP in cells?

Back

ATP (adenosine triphosphate) is the energy currency of the cell, providing energy for various cellular processes.
