Cellular respiration takes place in the mitochondria of cells.
While photosynthesis requires energy and produces food, cellular respiration breaks down food and releases energy.
They both consume and create the same substances (water, glucose, oxygen, and carbon dioxide) but in different ways.
Through these processes, plants obtain the carbon dioxide they need and living organisms obtain the oxygen they need.
Chlorophyll in the leaves transform carbon dioxide, water, and minerals into oxygen and glucose.
Photosynthesis takes place in the chloroplasts of cells.Plants perform both photosynthesis and respiration, while animals can only perform respiration.Related Links: Difference between Words Science Related Words Difference and Comparison Photosynthesis Quiz Photosynthesis Quiz Biology Difference Between Words: English and Science Vocabulary ...This process is what gives energy to all living organisms either directly or indirectly. on the other hand, is the process by which living things convert oxygen and glucose to carbon dioxide and water, thereby yielding energy.It does not require the presence of sunlight and is always occurring in living organisms.If enough oxygen is present, pyruvate moves into specialized organelles called mitochondria.There, it is broken down into acetate and CO, the Krebs Cycle and glycolysis use energy from the chemical bonds of substrates (such as glucose) to form high-energy compounds such as ATP and GTP, which are used by cell systems.In the electron transport chain, which in animal cells is located mostly on the inner membranes of mitochondria, reduced products such as NADH and FADH2 are used to create a proton gradient -- an imbalance in the concentration of unpaired hydrogen atoms on one side of the membrane vs. The proton gradient, in turn, drives the production of more ATP, in a process called oxidative phosphorylation.Overall, photosynthesis involves the energizing of electrons by light energy to reduce (add electrons to) CO2 to build a larger compound (glucose), producing oxygen as a byproduct.Photosynthesis emerged in organisms 3.5 billion years ago, has evolved complex biochemical and biophysical mechanisms, and today occurs in plants and single-celled organisms.It is because of photosynthesis that Earth's atmosphere and seas contain oxygen.
