the metabolic processes whereby certain organisms obtain energy from organic molecules; processes that take place in the cells and tissues during which energy is released and carbon dioxide is produced and absorbed by the blood to be transported to the lungs
The chemical equation describing this reaction, cellular respiration, could be written this way:
6O2 + C6H12O6 --> 6H2O + 6CO2 + energy
This means that in each individual reaction, the mitochondrion needs 6 oxygen molecules and a glucose molecule.
This energy is stored by building a special molecule called ATP, or adenosine triphosphate, in which the covalent bonds between atoms (in particular, between the phosphate components of the molecule) store a lot of energy.
a nucleotide derived from adenosine that occurs in muscle tissue; the major source of energy for cellular reactions
