Question

Quizplus · Accepted Answer

Respiration is the process in which carbohydrates are broken down in the presence of oxygen to release energy, carbon dioxide, and water. This process is also known as aerobic respiration. Therefore, option B is the best choice. Option A is incorrect because it describes a process known as photosynthesis, not respiration. Option C is also incorrect because it describes the opposite process, which is photosynthesis. Option D is incorrect because it does not involve the breakdown of carbohydrates to release energy, which is a defining characteristic of respiration.
