Photosynthesis
and Cellular respiration
| Term | Definition |
|---|---|
| NADPH | found in cellular respiration, carries electrons and is made in the first two steps, used in the third step |
| Adenosine Triphosphate | cluster of proteins that span the cell membrane and allow hydrogen ions(H+) to pass through it. Energy molecule |
| lactic acid | the build-up of carbon dioxide in your muscles/combination of two CO2 molecules |
| Fermentation | the process by which cells release energy in the absence of oxygen |
| Krebs cycle | the second stage of cellular respiration in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions |
| pyruvic acid | the end product of glycolysis |
| conversion stage | in cellular respiration, intermediate step between glycolysis and the citric acid cycle (steps 1 and 2) pyruvic acid to the mitochondria |
| Glycolysis | First set of reactions in cellular respiration in which a molecule of glucose is broken into two molecules of pyruvic acid |
| Anaerobic | process that does not require oxygen |
| Aerobic | process that requires oxygen |
| cam plants | keeps stomata closed during hot and dry days to keep water in cacti and pineapple are examples of these |
| Photosynthesis | process used by plants and other autotrophs to capture light energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy rich carbohydrates such as sugars and starches (CO2) |
| Calvin cycle | light independent reactions of photosynthesis in which from ATP and nadph is used to build high energy compounds such as sugar |
| electron transport chain | series of electron carrier proteins that shut the high energy electrons during ATP generating reactions |
| photo systems | cluster of chlorophyll and proteins found in thylakoids |
| light independent reactions | set of reactions in photosynthesis that do not require light; energy from ATP and nadph is used to build high energy compounds such as sugar; also called the Calvin cycle |
| light dependent reaction | set of reactions in photosynthesis that use energy from light to produce ATP and nadph |
| Stroma | fluid portion of the chloroplast; outside of the thylakoids |
| Thylakoids | sac-like photosynthetic membranes found in chloroplasts |
| Chlorophyll | principal Pigment of plants and other photosynthetic organisms |
