The main function of photosynthesis is to produce food and capture energy.
Photosynthesis is divided into two stages: the Light Dependent Reaction and the Light Independent reaction which is also referred to as the Calvin Cycle.
What is Cellular Respiration?
Cellular respiration is a series of redox reactions as well as other reactions in order to create energy in the form of ATP.
Throughout the redox reactions in cellular respiration, other energy molecules such as Nicotinamide Adenosine Dinucleotide + hydrogen (NADH) and Flavin Adenosine Dinucleotide + 2 hydrogen (FADH₂) are formed as well.
All living things get the energy they need to live from a chemical reaction called respiration. This process needs glucose as a starting point. First we'll see how respiration works, and then look at how plants use respiration in combination with photosynthesis.
Plant cells respire, just as animal cells do. If they stop respiring, they will die. Remember that respiration is not the same as breathing, so take care - plants do not breathe.
As we can see from the word equations respiration and photosynthesis are opposites. Respiration uses oxygen and produces carbon dioxide. Photosynthesis uses carbon dioxide and produces oxygen.
Energy is stored in a nutrient’s chemical bonds. Energy comes from sunlight, which plants then capture and, via photosynthesis, use it to transform carbon dioxide in the air into the molecule, glucose. When the glucose bonds are broken, energy is released. Bacteria, plants, and animals (including humans) harvest the energy in glucose via a biological process called . In this process the chemical energy of glucose is transformed into cellular energy in the form of the molecule, adenosine triphosphate (ATP). Cellular respiration requires oxygen (aerobic) and it is provided as a waste product of photosynthesis. The waste products of cellular respiration are carbon dioxide (CO2) and water, which plants use to conduct photosynthesis again. Thus, energy is constantly cycling between plants and animals. As energy is consumed nutrients are recycled within it.
The main function of cellular respiration is to break down food and release energy.
There are two types of cellular respiration: aerobic and anaerobic.
Referring back to the introduction, cellular respiration and photosynthesis go through different stages each involving different reactions.
Divided into two stages
: Light dependent reaction and Light Independent reaction/Calvin cycle
While cellular respiration requires oxygen as a reactant to release carbon dioxide, photosynthesis requires carbon dioxide as a reactant to release oxygen.
Stages of Cellular Respiration and Photosynthesis:
Protons make it back into matrix and water is created.
Photosynthesis and cellular respiration are reactions that both play an important role in the carbon cycle.
Similarities and Differences
By Julie Usih
Plants cannot perform
without sunlight due to the fact that photosynthesis is a process in which it converts solar energy (from the sun) into chemical energy.
Electron Transport Chain (ETC)
– This is the final step of cellular respiration where NADH and FADH₂ are oxidized to be reused in order to create ATP and water.
Reactants and Products:
Electron Transport Chain (ETC)
Both photosynthesis and cellular respiration use the ETC to pump protons into the membrane.

- Photosynthesis removes CO2 from the atmoshere and cellular respiration puts it back.
-Photosynthesis releases oxygen into the atmoshere and cellular respiration uses that oxygen to release energy from food.
