What is the opposite of respiration
Photosynthesis is the opposite reaction of cellular respiration
We also have to be careful when studying green plants because in the light the green parts of these plants carry out photosynthesis as well as respiration.
What is the opposite of photosynthesis
Photosynthesis does the opposite of respiration. Carbon dioxide is absorbed and oxygen is produced. In order to study respiration in green plants we must block out the light, because although green plants respire all the time they only photosynthesize in the light.

In respiration energy is released fromsugars when electrons associated with hydrogen are transported to oxygen (theelectron acceptor), and water is formed as a byproduct. The mitochondriause the energy released in this oxidation in order to synthesize ATP. Inphotosynthesis, the electron flow is reversed, the water is split (not formed),and the electrons are transferred from the water to CO2 and in theprocess the energy is used to reduce the CO2 into sugar. Inrespiration the energy yield is 686 kcal per mole of glucose oxidized to CO2,while photosynthesis requires 686 kcal of energy to boost the electrons from thewater to their high-energy perches in the reduced sugar -- light provides thisenergy.

I’m actually curious about this – Because over-planting a small pond, and having the plants use up too much oxygen during the night to the point that the fish die or are gasping for air at the surface by morning because of it, is a not uncommon problem. Would you know why there is such a difference? Like do aquatic plants have higher oxygen usage in a lower oxygen environment, perhaps, or it’s a more enclosed space with much higher percentage of plants per area, or something else?
