A simplification is that respiration takes oxygen out of the environment and releases carbon dioxide, and photosynthesis takes in carbon dioxide and releases oxygen. They kind of work together in a cycle.
Carbon dioxide
Cellular Respiration
after photosynthesis occurs
photosynthesis
The reverse is photosynthesis.
There is no replication of the DNA in cellular respiration or photosynthesis. In cellular respiration, you have biological oxidation of the glucose molecule. In case of the photosynthesis you have the reverse process that takes place.
The opposite is cellular respiration, more specifically aerobic respiration. This process uses oxidation to release the energy stored in carbohydrates.
Cellular respiration is the process that "withdraws" the energy.
The products of photosynthesis are used in the process of cellular respiration and vice versa.
respiration
respiration is the process of breaking down food molecules in order to release energy for work while the photosynthesis is the food making process in plants.
Photosynthesis makes glucose molecules, but cellular respiration breaks them down.
