Which biological process involves the use of oxygen, water, and carbohydrates to produce energy?

The biological process that utilizes oxygen, water, and carbohydrates to produce energy is cellular respiration. This process occurs in the cells of organisms and is essential for converting the chemical energy stored in carbohydrates into a usable form of energy, which is ATP (adenosine triphosphate). During cellular respiration, glucose (a carbohydrate) is oxidized in the presence of oxygen, resulting in the production of carbon dioxide, water, and ATP. This energy is vital for various cellular activities and overall functioning of living organisms.

Photosynthesis is the process by which plants, algae, and some bacteria convert light energy into chemical energy stored in glucose, utilizing carbon dioxide and water, but it does not primarily focus on energy production through the consumption of carbohydrates and oxygen.

Fermentation is an anaerobic process that occurs in the absence of oxygen, leading to the breakdown of carbohydrates to produce energy, but it is less efficient compared to cellular respiration.

Digestion refers to the breakdown of food into smaller molecules, which includes carbohydrates, proteins, and fats, but it is not the process that directly converts these substances into energy.

Thus, cellular respiration is specifically associated with the use of oxygen, water, and carbohydrates to generate energy efficiently in living cells.
