This tutorial introduces mitochondria
The carbon dioxide gas you exhale is the result of a completed cycle of cellular respiration.Only plants can photosynthesize, but both plants and animals depend on respiration to release the chemical potential energy originally captured through photosynthesis.The figure illustrates how closely photosynthesis and respiration are linked.
BioCoach Activity Cell Respiration Introduction
In both plants and animals, the process of — which releases stored energy for use — occurs in the mitochondria inside each cell.Chemically speaking, respiration is photosynthesis in reverse, as you can see in this equation:
C6H12O6 + 6O2 → 6H2O + 6CO2+ energyRespiration consists of a complicated series of chemical reactions.
The term cellular respiration refers to the biochemical pathway by which cells release energy from the chemical bonds of food molecules and provide that energy for the essential processes of life. All living cells must carry out cellular respiration. It can be in the presence of oxygen or . carry out cellular respiration within the cytoplasm or on the inner surfaces of the cells. More emphasis here will be placed on where the are the site of most of the reactions. The energy currency of these cells is , and one way to view the outcome of cellular respiration is as a production process for ATP.
