Immediate source of energy for cellular respiration is:
Correct answer: B. ATP
- A. Lipids
- B. ATP
- C. Proteins
- D. Carbohydrates
Explanation
The immediate source of energy for cellular respiration is adenosine triphosphate, or ATP. ATP is a molecule that stores and releases energy in cells. During cellular respiration, the complex organic molecules, such as glucose, are gradually broken down in a series of enzymatic reactions. The energy released during these reactions is used to synthesize ATP from adenosine diphosphate (ADP) and inorganic phosphate (Pi).
