Which phrase best describes cellular respiration?
A. The process where energy from food is used by the cell
B. The process where water molecules move across a membrane
C. The process by which the cytoplasm physically divides
D. The process where molecules' movements balance out their distribution
Answer (2)
During respiration, cells use the simplest, digested form of carbohydrate foods, glucose, and produce energy from it. The reaction takes place in the presence of oxygen and its by-products are carbon dioxide and water. Therefore, the answer is the process where energy from food is used by the cell.
Cellular respiration is the process by which cells convert glucose and oxygen into energy (ATP), carbon dioxide, and water. This cycle is essential for living organisms as it provides the energy necessary for life functions. Therefore, the best description of cellular respiration is: A. The process where energy from food is used by the cell.
