Document Summary
Sugars can be converted to amino acids that are linked together into proteins when needed: can also happen conversely with food. Cellular respiration: drives the cellular economy by extracting the energy stored in sugars and other fuels: cells use this energy to do work like transport solutes across the plasma membrane. Dinoflagellates: free-floating single celled marine organism: they convert energy stored in certain organic molecules to light. Most bioluminescent organism found in ocean: some found on land like fungus. Metabolism: the totality of an organism"s chemical reaction: emergent property of life that arises from orderly interactions between molecules, manages the material and energy resource of the cell. Organization of the chemistry of life into metabolic pathways. Metabolic pathways: begins with a specific molecule, which is then altered in a series of defined steps, resulting in certain product. Each step of the pathway is catalyzed by a specific enzyme. *pathways can have more than one starting molecule and/or product.
