| Term | Definition |
|---|---|
| adenosine diphosphate | a nucleotide that functions in the transfer of energy during the catabolism of glucose, formed by the removal of a phosphate from adenosine triphosphate and composed of adenine, ribose, and two phosphate groups. |
| adenosine triphosphate | a nucleotide that is the primary source of energy in all living cells because of its function in donating a phosphate group during biochemical activities; composed of adenosine, ribose, and three phosphate groups |
| calvin cycle | A series of chemical reactions that occurs as part of the dark reactions of photosynthesis, in which carbon is broken away from gaseous carbon dioxide and fixed as organic carbon in compounds that are ultimately used to make sugars and starch as food. |
| chlorophyll | the green pigment of plant leaves and algae, essential to their production of carbohydrates by photosynthesis. |
| electron transport chain | series of compounds that transfer electrons from electron donors to electron acceptors via redox reactions, and couples this electron transfer with the transfer of protons (H+ ions) across a membrane. |
| light-dependent reactions | Any of the chemical reactions that take place during the first stage of photosynthesis and require the presence of light. |
| light-independent reactions | Any of the chemical reactions that take place during the second stage of photosynthesis and do not require light |
| NADP+ | Nicotinamide adenine dinucleotide phosphate, abbreviated NADP+ or, in older notation, TPN (triphosphopyridine nucleotide), is a coenzyme used in anabolic reactions, such as lipid and nucleic acid synthesis, which require NADPH as a reducing agent. |
| Photolysis | To replace lost electrons molecules of water are split in the first photosystem |
| Photosynthesis | The proscess that uses the sun's energy to make simple sugers |
| Pigment | Molecules that absorbspecific wavelengths of sunlight |
| Aerobic | living, active, or occurring only in the presence of oxygen |
| alcoholic fermentation | a process in which some sugars (as glucose) are converted into alcohol and carbon dioxide by the action of various yeasts, molds, or bacteria on carbohydrate materials |
| anaerobic | living, active, or occurring in the absence of free oxygen |
| cellular respiration | any of various energy-yielding oxidative reactions in living matter that typically involve transfer of oxygen and production of carbon dioxide and water as end products |
| citric acid cycle | a sequence of reactions in the living organism in which oxidation of acetic acid or acetyl equivalent provides energy for storage in phosphate bonds |
| glycolysis | the enzymatic breakdown of a carbohydrate (as glucose or glycogen) by way of phosphate derivatives with the production of pyruvic or lactic acid and energy stored in high-energy phosphate bonds of ATP |
| latic acid fermentation | is a biological process by which glucose, fructose, and sucrose are converted into cellular energy and the metabolite lactate |
