In non-cycliCalvin cycle (C₃ pathway) occurs in:In C₃ cycle, first stable product is:How many CO₂, ATP, NADPH needed to make one glucose via Calvin cycle?Number of ATP and NADPH consumed in Calvin cycle PER turn (per CO₂ fixed):Most plants are:In photolysis of water:During photosynthesis, ATP is produced primarily by:Maximum photosynthesis occurs at:Photosynthesis takes place primarily in theIn a chloroplast, the light reactions take place in theWhich of the following is the MOST abundant pigment of higher plants?Maximum absorption of light by chlorophyll a is in theOxygen evolved during photosynthesis comes fromThe Calvin cycle takes place in theRuBisCO catalyses the carboxylation ofThe first stable product of the C3 (Calvin) pathway isLight saturation in photosynthesis typically occurs atJoseph Priestley's classic experiment with a mouse and a candle in a bell jar demonstrated thatThe reaction centre of Photosystem I isThe non-cyclic electron flow (Z-scheme) producesCyclic photophosphorylation involvesSplitting of water (photolysis) is associated withTo synthesise one molecule of glucose, the Calvin cycle usesThe C4 pathway is also known as theKranz anatomy is found inIn C4 plants, the primary CO2 acceptor isPhotorespiration is theC4 plants lack photorespiration becauseBlackman's Law of Limiting Factors states thatAccessory pigments (chlorophyll b, xanthophylls, carotenoids) function byIn the Z-scheme, electrons removed from PS II are replenished byChemiosmotic hypothesis applied to chloroplasts holds thatThe stages of the Calvin cycle in order areThe light-harvesting complex (LHC) and reaction centre of a photosystem differ in thatIn C4 plants, decarboxylation of malate or aspartate in bundle sheath cellsEngelmann's experiment with Cladophora and aerobic bacteria established theThe two products of the photolysis of water that contribute to the proton gradient and ATP yield areIn photosynthesis, the role of NADPH made during the light reactions is toPhotosynthesis primarily occurs in which organelle?Chlorophyll absorbs light most strongly inThe Calvin cycle (dark reactions) occurs inThe oxygen released during photosynthesis comes fromThe enzyme that fixes CO₂ in the Calvin cycle isThe first stable product of CO₂ fixation in C4 plants isIn photosynthesis, the oxygen released into the atmosphere comes fromInside a leaf cell, photosynthesis is carried out inWhy do healthy leaves look green?The molecular oxygen released during photosynthesis comes fromCyclic photophosphorylation differs from non-cyclic in that itPer Mitchell's chemiosmotic hypothesis, ATP synthesis in chloroplasts is driven byThe enzyme RuBisCO catalyses the joining of CO₂ to which molecule?To synthesise one molecule of glucose, the Calvin cycle must consumeC3 plants are so named becauseKranz anatomy of C4 plants isPhotorespiration in C3 plants is wasteful becauseBlackman's law of limiting factors says thatThe MAIN photosynthetic pigment in green plants is:Light reactions of photosynthesis occur in the:In photosynthesis, the source of O2 released into the atmosphere is:In the Z-scheme of photosynthesis, electrons flow:In the Calvin cycle, CO2 is fixed by the enzyme:The C4 pathway (Hatch-Slack) uses which enzyme for the initial CO2 fixation?CAM plants (like cactus and pineapple) open their stomata mainly:The colour of light LEAST absorbed by chlorophyll (and most reflected by leaves) is:Blackman's law of LIMITING FACTORS states that the overall rate of photosynthesis is determined by:
