2. Cellular respiration - Wikipedia

   en.wikipedia.org/wiki/Cellular_respiration

   Cellular respiration may be described as a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from nutrients into ATP, and then release waste products. [1] Cellular respiration is a vital process that occurs in the cells of all [[plants and some bacteria ]].

3. Photosynthesis - Wikipedia

   en.wikipedia.org/wiki/Photosynthesis

   In general outline, photosynthesis is the opposite of cellular respiration: while photosynthesis is a process of reduction of carbon dioxide to carbohydrates, cellular respiration is the oxidation of carbohydrates or other nutrients to carbon dioxide. Nutrients used in cellular respiration include carbohydrates, amino acids and fatty acids.

4. Bioenergetics - Wikipedia

   en.wikipedia.org/wiki/Bioenergetics

   Bioenergetics is a field in biochemistry and cell biology that concerns energy flow through living systems. [1] This is an active area of biological research that includes the study of the transformation of energy in living organisms and the study of thousands of different cellular processes such as cellular respiration and the many other metabolic and enzymatic processes that lead to ...

5. Ecosystem respiration - Wikipedia

   en.wikipedia.org/wiki/Ecosystem_respiration

   Cellular respiration happens when a cell takes glucose and oxygen and uses it to produce carbon dioxide, energy, and water. This transaction is important not only for the benefit of the cells, but for the carbon dioxide output provided, which is key in the process of photosynthesis .

6. Evolution of photosynthesis - Wikipedia

   en.wikipedia.org/wiki/Evolution_of_photosynthesis

   The evolution of photosynthesis refers to the origin and subsequent evolution of photosynthesis, the process by which light energy is used to assemble sugars from carbon dioxide and a hydrogen and electron source such as water. It is believed that the pigments used for photosynthesis initially were used for protection from the harmful effects ...

7. Carbohydrate metabolism - Wikipedia

   en.wikipedia.org/wiki/Carbohydrate_metabolism

   When animals and fungi consume plants, they use cellular respiration to break down these stored carbohydrates to make energy available to cells. [2] Both animals and plants temporarily store the released energy in the form of high-energy molecules, such as adenosine triphosphate (ATP), for use in various cellular processes.

8. Respiration (physiology) - Wikipedia

   en.wikipedia.org/wiki/Respiration_(physiology)

   Although physiologic respiration is necessary to sustain cellular respiration and thus life in animals, the processes are distinct: cellular respiration takes place in individual cells of the organism, while physiologic respiration concerns the diffusion and transport of metabolites between the organism and the external environment.

9. Cellular waste product - Wikipedia

   en.wikipedia.org/wiki/Cellular_waste_product

   Cellular waste products are formed as a by-product of cellular respiration, a series of processes and reactions that generate energy for the cell, in the form of ATP. One example of cellular respiration creating cellular waste products are aerobic respiration and anaerobic respiration .
