The correct answer is ATP stores the energy. During cellular respiration, which is the process by which cells convert glucose and oxygen into carbon dioxide, water, and ATP (adenosine triphosphate), ATP plays a crucial role in storing and transferring the energy released.
To arrive at this answer, you can remember the basic steps of cellular respiration, which involve breaking down glucose molecules to release energy. Glucose is initially converted to a molecule called pyruvate during glycolysis, which takes place in the cytoplasm of cells. Only a small amount of ATP is produced during this step.
The pyruvate molecules then enter the mitochondria, where they undergo further reactions that result in the production of ATP. In the presence of oxygen, pyruvate is converted to acetyl-CoA, which enters the citric acid cycle (also known as the Krebs cycle). During this cycle, several reactions occur, releasing high-energy electrons that are captured by molecules like NADH and FADH2. These high-energy electrons eventually get transferred to the electron transport chain.
In the electron transport chain, the energy carried by the electrons is used to pump protons across the inner mitochondrial membrane. This creates a proton gradient, which drives the synthesis of ATP from ADP (adenosine diphosphate) and inorganic phosphate through a process called oxidative phosphorylation. The ATP produced is now carrying the energy released during cellular respiration and can be utilized by cells for various functions.
Therefore, it is ATP, not carbon dioxide, oxygen, or glucose, that stores the energy generated through cellular respiration.
