245999553 | Light independent reactions (calvin cycle) | plants use energy that ATP and NADPH contain to build stable high energy carbohydrate compounds that can be stored for a long time. These are the steps in which the hydrogen (H) that is held by the NADPH is combined with Co2 through a series of steps to form glucose ATP and NADPH provide the energy to power this cycle | |
245999554 | 3 steps of calvin cycle | must turn 6 times in order to produce 1 glucose. 1. CO2 fixation 2. CO2 reduction 3. Regeneration of RuBP 4. production of glucose (not part of actual cycle) | |
245999555 | CO2 Fixation | attachment of CO2 to RuBP to form an unstalbe intermediate, immediately breaks down into 2 three-carbon PGAs | |
245999556 | CO2 Reduction | Adds an electron or hydrogen ion. PGA is reduced to PGAL (PGA turns into PGAP first then to PGAL) ATP and NADPH are used here | |
245999557 | Regeneration of RuBP | 6 turns of cycle yield 2 PGALs that are used for production of glucose and 10 can be recycled back into six 5-carbon RuBPs | |
245999558 | C3 photosynthesis | typical calvin cycle ex: most typical plants | |
245999559 | C4 photosynthesis | CO2 is fixed to form a 4-carbon molecule called oxaloacetic acid (OAA). OAA is then converted to malate and transferred into bundle sheath cells. Plants grow in huge amount in short time. ex: crabgrass, corn, and sugar cane | |
245999560 | CAM | fixes CO2 to a 4-carbon molecule, called OAA, at night OAA is then converted to malic acid and transferred to the vacuole at night when the stomata can open ex: desert plants | |
245999561 | Photorepiration | caused when a protein found in plants, called rubisco, fixes O2 instead of CO2 like it normally does. Rubisco is not an efficient protein. O2 fixations causes products other than glucose in which peroxisomes must rid the cell of. 30-40% of all energy in light reactions is used to overcome it. | |
252870084 | Metabolic Pathway | the series of chemical (enzyme controlled) reactions which turn one chemical into another | |
252870085 | First law of thermodynamics | energy cannot be created or destroyed, only converted from one form to another | |
252870086 | second law of thermodynamics | in any spontaneous process, there is always an increase in the entropy (randomness or disorder) of the universe. | |
252870087 | ATP | energy storage molecule in the cell, easily obtainable energy, energy currency of the cell | |
252870088 | Aerobic | respiration with oxygen to make ATP energy in living organisms | |
252870089 | Anaerobic | (fermentation) respiration without oxygen | |
252870090 | Glycolysis | Both anaerobic and aerobic start with this, it occurs in the cytoplasm, converts glucose to pyruvic acid, and produces 2 ATP and 2 NADH | |
252870091 | Lactic Acid fermentation | (in the cytoplasm of animals and bacteria) pryuvic acid is converted to lactic acid | |
252870092 | Alcoholic fermentation | (in the cytoplasm of yeast and plants) converts pyruvic acid into ethyl alcohol and carbon dioxide | |
252870093 | coupled reactions | when a non-spontaneous reaction (endergonic) is "coupled" to a spontaneous reaction (exergonic) in order to conserve energy | |
252870094 | substrate level phosphorylation | when a high energy phosphate is transferred directly from a phoshporylated metabolic compound to a molecule of ADP | |
252870095 | Oxidative phosphorylation | electrons are removed from carrier molecules (NAD and FAD) and passed through a series of electron carrier proteins which "pump" hydrogen into the intermembrane space of the mitochondria | |
252870096 | Efficiency of aerobic respiration | 7.3kcal-mol of ATP x 36 ATP/ 686 kcal-mol glucose, 39% of the available energy is extracted from the glucose molecule | |
252870097 | Creatine Phosphate | (3x to 5x more plentiful than ATP) transfers a phosphate to ADP immediately, compound in muscular cells | |
252870098 | anaerobic glycolysis | (after creatin phosphate is used up) produces lactic acid | |
252870099 | Phosphagen system in muscles | All the creatine and ATP in the muscle have about 15 seconds of maixmal contraction |
