Who uses photosynthesis? - ANSWER autotrophs Where does photosynthesis occur? - ANSWER chloroplasts chemosyntheis - ANSWER used by prokaryotic autotrophs as an inorganic chemical reaction to produce energy heterotrophs - ANSWER require food and use cellular respiration to release energy from chemical bonds in the food who uses cellular respiration to release energy from stored food? - ANSWER all organisms light capturing events - ANSWER The first stage in photosynthesis; thylakoids found in the chloroplasts capture light energy and produce excited electrons light-dependent reactions - ANSWER convert light energy and water into ATP, NADPH, and O2 by the way of moving excited electrons in the stroma of plant cells Light Independent Reactions - ANSWER Use ATP and NADPH (from the light-dependent reactions) plus CO2 to produce carbohydrate sugars photorespiration - ANSWER a wasteful process that uses energy and decreases sugar synthesis that occurs in plants during photosynthesis. It occurs when the enzyme rubisco binds to oxygen instead of atmospheric CO2. How do C4 plants minimize photorespiration? - ANSWER The light reactions and the Calvin cycle occur in different cells, so oxygen does not come into contact with rubisco. How do CAM plants minimize photorespiration? - ANSWER Stomata are only opened at night, storing carbon dioxide in malate. During the day the carbon dioxide is released for photosynthesis. how do C3 plants minimize photorespiration? - ANSWER They don't. They have no special adaptations to do so. This is more than 85% of plants! aerobic respiration - ANSWER Respiration that requires oxygen. a series of enzyme-controlled reactions in which oxygen + glucose -> CO2 + H2O + energy (ATP).
