Calvin Cycle | (also known as the Calvin–Benson cycle) is the set of chemical reactions that take place in chloroplasts during photosynthesis. The cycle is light-independent because it takes place after the energy has been captured from sunlight. |
Light dependent | The reaction taking place in the chloroplast in which the absorption of a photon leads to the formation of atp and nadph. |
Light independent | The light-independent reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. These reactions occur in the stroma, the fluid-filled area of a chloroplast outside of the thylakoid membranes. |
Chloroplast | (in green plant cells) a plastid that contains chlorophyll and in which photosynthesis takes place. |
Chlorophyll | a green pigment, present in all green plants and in responsible for the absorption of light to provide energy for photosynthesis. |
Thylakoid | each of a number of flattened sacs inside a chloroplast, bounded by pigmented membranes on which the light reactions of photosynthesis take place, |
Grana | the stacks of thylakoids embedded in the stroma of a chloroplast. |
Stroma | the supportive tissue of an epithelial organ, tumor, gonad, etc., consisting of connective tissues and blood vessels. |
citric acid cycle | another term for Krebs cycle. |
Krebs Cycle | the sequence of reactions by which most living cells generate energy during the process of aerobic respiration. It takes place in the mitochondria, consuming oxygen, producing carbon dioxide and water as waste products, and converting ADP to ATP. |
Mitochondria | an organelle found in large numbers in most cells, in which the biochemical processes of respiration and energy production occur. It has a double membrane, the inner layer being folded inward to form layers |
Cytoplasm | the material within a living cell, excluding the nucleus. |
Pyruvic Acid | a yellowish organic acid that occurs as an intermediate in many metabolic processes, especially glycolysis. |
ETC | An electron transport chain (ETC) is a 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. |
Aerobic Respiration | a type of respiration in which oxygen is taken in and carbon dioxide and water are produced; also, the use of oxygen in the breakdown of foodstuffs to create energy |
Anaerobic Respiration | in biology, a form of incomplete intracellular breakdown of sugar or other organic compounds in the absence of oxygen that releases energy; cellular respiration in the absence of oxygen |
Fermentation | complex organic compounds, such as glucose, are broken down by enzymes into simpler compounds without oxygen. It results in the production of energy in the form of 2 ATP molecules, and produces less energy than the aerobic process of cellular respiration. |
Alcoholic Fermentation | a type of cellular Respiration which does not require oxygen (anaerobic respiration), and involves the breaking down of glucose to pyruvic acid and then finally ethanol. |
Lactic Acid Fermentation | Process carried out by lactic acid bacteria when oxygen is not present. |
