ATP & Respiration

What is the primary purpose of cellular respiration?

• To produce glucose for energy storage

• To derive energy from the food we eat

• To create electrical impulses in nerves

• To transport materials in and out of cell membranes

What is ATP commonly called in the context of biological energy?
