Enzymes are proteins that act as catalysts for reactions, such as those in cellular respiration. They increase the likelihood of a reaction by lowering the energy required for a reaction to occur. In the process, enzymes are left unchanged by the reaction. They may stress bonds in a molecule and increase the chance of that bond breaking and they may force molecules or atoms together and help in the formation of a new bond. The molecules that bind to the enzyme are called substrates. The resulting molecules from the reaction are called products. Enzymes may have more than one binding site.

Cellular respiration , the process by which organisms combine oxygen with foodstuff molecules , diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water. Organisms that do not depend on oxygen degrade foodstuffs in a process called fermentation. For longer treatments of various aspects of cellular respiration, see tricarboxylic acid cycle and metabolism. One objective of the degradation of foodstuffs is to convert the energy contained in chemical bonds into the energy-rich compound adenosine triphosphate ATP , which captures the chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes. In eukaryotic cells that is, any cells or organisms that possess a clearly defined nucleus and membrane-bound organelles the enzymes that catalyze the individual steps involved in respiration and energy conservation are located in highly organized rod-shaped compartments called mitochondria. In microorganisms the enzymes occur as components of the cell membrane.

Respiration using oxygen to break down food molecules is called aerobic respiration. Glucose is the molecule normally used for respiration - it is the main respiratory substrate., The relationship between photosynthesis and cellular respiration is such that the products of one system are the reactants of the other. Photosynthesis involves the use of energy from sunlight, water and carbon dioxide to produce glucose and oxygen.


Cells are microscopic, multipurpose containers that represent the smallest indivisible units of life in that they manifest reproduction, metabolism and other "lifelike" qualities. In fact, since prokaryotic organisms members of the Bacteria and Archaea classification domains almost always consist of a single cell, many stand-alone cells are literally alive. Cells make use of a molecule called adenosine triphosphate, or ATP, as a source of fuel. Prokaryotes rely solely on glycolysis the breakdown of glucose into pyruvate as a pathway to synthesizing ATP; this process yields a total of 2 ATP per molecule of glucose. In contrast, eukaryotes animals, plants and fungi are both far larger and in possession of far more complex individual cells than prokaryotes, making glycolysis alone inadequate for their energy needs.
