1 1 Which of the following organisms do NOT carry on photosynthesis? plants algae some bacteria 2 3 animals The correct description of the relationship between photosynthesis and the living world is. herbivores, carnivores, and omnivores are autotrophs because they can "eat for themselves." heterotrophs are called "hetero" because they change sunlight energy into chemical energy. all heterotrophs are ultimately dependent upon food produced by autotrophs. herbivores are autotrophs, carnivores are heterotrophs, and omnivores are half autotrophs and half heterotrophs. On the visible spectrum, energy content of light is greatest for. red light yellow light green light violet light 4 All colors contain the same amount of light energy. Stacks of membranous compartments within the chloroplast are called. thylakoids grana stroma cristae 5 matrix The fluid-filled space surrounding the grana is called the.

2 matrix cristae stroma thylakoid space 6 intermitochondrial space Which type of reactions begin after the thylakoids absorb solar energy? light reactions Calvin cycle reactions glycolysis citric acid cycle 7 fermentation Which of the following molecules is produced during the light reactions of photosynthesis and used in the Calvin cycle reactions? oxygen and glucose carbon dioxide, NADPH, and ATP oxygen, NADPH, and ATP NADPH and ATP 8 NADH and ATP Which type of photosynthetic reaction will involve the splitting of water and the release of oxygen? non glycolysis citric cycle

3 9 fermentation If light were maximally absorbed by a photosynthetic system, what would be the effect on the rate of photosynthesis if the temperature were increased? The rate of photosynthesis would remain the same. The rate of photosynthesis would decrease. 10 The rate of photosynthesis would increase. Excited electrons leave the Photosystem I reaction center chlorophyll and are taken up by an electron acceptor, which passes them down an electron transport system before they return to Photosystem I. This pathway is called the. glycolysis reactions citric acid cycle light reactions non 11 Which of the following pathways will produce oxygen during photosynthesis? electron transport pathway non Calvin cycle reactions 12 Krebs cycle Which of the following molecules will be used to form oxygen during photosynthesis? pyruvate PGAL glucose carbon dioxide

4 13 water Which molecule transports hydrogen from the light reactions to the Calvin cycle reactions? NADP NAD cytochrome water 14 PS II Which metabolic pathway will produce carbohydrate? non glycolysis Calvin cycle 15 citric acid cycle Which stage of the Calvin cycle will require both ATP and NADPH from the light reactions? carbon dioxide fixation carbon dioxide reduction regeneration of RuBP 16 non CAM plants differ from C 3 plants because they. produce a carbon-and-monosaccharide (CAM) sugar product. lack a light-independent cycle. form a C 3 molecule prior to entering the Calvin cycle.

5 17 fix CO 2 by forming a C 4 molecule at night when water loss through stomata is minimized. Which of the following comparisons of cellular respiration versus photosynthesis is NOT correct? Mitochondrion-Chloroplast Oxidation-Reduction Releases energy-requires energy Releases CO 2-Requires CO 2 18 Releases oxygen-requires oxygen Which of the following statements is NOT correct about photosynthesis? Photosynthesis occurs within the chloroplast. During photosynthesis, carbon dioxide is reduced. During photosynthesis, oxygen is released. During photosynthesis, the hydrogen carrier is NAD. 19 During photosynthesis, solar energy is used. Small openings found on a leaf that allow carbon dioxide to enter are called. thylakoids chlorplasts stomata 20 grana Different allow organisms to capture different wavelengths of the sunlight. enzymes pigments carbohydrates chlorophyll
