Question

which organisms can perform cellular respiration?
only autotrophs
only animals
only heterotrophs
autotrophs and heterotrophs

Explanation:

Cellular respiration is a fundamental metabolic process that occurs in the cells of most living organisms. It involves the breakdown of glucose (or other organic molecules) in the presence of oxygen to produce energy (in the form of ATP), carbon dioxide, and water.

Autotrophs, such as plants and some bacteria, can perform photosynthesis to produce their own food (glucose). However, they also need to break down this glucose to release energy for their cellular activities. This breakdown of glucose occurs through cellular respiration.

Heterotrophs, including animals, fungi, and most bacteria, cannot produce their own food. They obtain glucose by consuming other organisms. Once they have glucose, they also use cellular respiration to break it down and release energy.

So, both autotrophs and heterotrophs perform cellular respiration.
