respiration
This process is called cellular respiration. During cellular respiration, organisms break down glucose with the help of oxygen to produce ATP, the energy currency of cells. This process occurs in the mitochondria of cells.
Oxygen and glucose combine during cellular respiration to produce energy in the form of adenosine triphosphate (ATP) in cells. This process is essential for the survival and functioning of living organisms.

Oxygen in the air combines with food and fuel during the process of combustion to produce energy, in the form of heat and light. This reaction is vital for organisms to generate the energy needed for various metabolic processes.
evolution
All organisms produce ATP (adenosine triphosphate) during respiration, which is the energy currency of the cell. This process involves breaking down glucose in the presence of oxygen to produce ATP, carbon dioxide, and water.
In addition to chloroplasts, organisms need sunlight, water, and carbon dioxide to perform photosynthesis. Sunlight provides the energy needed for the process, while water and carbon dioxide are raw materials used to produce glucose and oxygen during photosynthesis.
Reactants are the starting materials of a reaction. Reactants combine to form the products.
No. The reactants are the initial materials that undergo chemical reaction; the new materials produced have the unsurprising name "products".
During nuclear fusion, atoms of low-mass materials (such as hydrogen) combine to form a substance of higher mass (such as helium). This process releases large amounts of energy in the form of light and heat. It is the reaction that powers the sun and other stars.
No, not all organisms produce carbon dioxide as a waste product. Plants and algae, for example, actually consume carbon dioxide during photosynthesis and produce oxygen as a byproduct. However, animals, including humans, do produce carbon dioxide as a waste product through respiration.
No, not all photosynthetic organisms are oxygenic. Oxygenic photosynthesis is the main process in which plants, algae, and cyanobacteria produce oxygen as a byproduct. However, there are some photosynthetic bacteria that do not produce oxygen during photosynthesis.
