It is transferred from cell to cell to provide energy. c)ATP hydrolysis is coupled to endergonic reactions to drive them. d)ATP is one of the building blocks of fats. 2.The overall reaction of photosynthesis was expressed as A and B: A: CO2 + 2H2O + light → (CH2O)n + H2O +O2 B: 6CO2 + 12H2O + light → C6H12O6 + 6H2O + 6O2 Why B is more accurate than A? ____________________________________ 3.Which compound(s) act as shuttles that transfer electrons between complex proteins? a)ubiquinone and cytochrome c b)cytochrome c c)cytochrome a d)ubiquinone 4.Why not just stop at pyruvate in the absence of oxygen? Why lactate? a)The reaction from pyruvate to lactate converts NADH back to NAD+, which is required for glycolysis. b)The reaction from pyruvate to lactate converts ADP to ATP. c)The reaction from pyruvate to lactate converts ATP to ADP. d)The reaction from pyruvate to lactate generates energy. 5.In terms of energy production, what is the most important product produced by the Krebs cycle? a)ATP b)CO2 c)NADH and FADH2 d)glucose 6.Which wavelength can oxidizing water? a)wavelength 700 nm b)wavelength 680 nm c)wavelength of both 700 nm and 680 nm d)wavelength 600 nm e)wavelength of both 700 nm and 600 nm 7.What is the Emerson enhancement effect of red and far red light? ___________________________________________________ 8.During photosynthesis when PSII is active, electron motive force is forming resulting a)stroma pH 8 and thylakoid lumen pH 5 b)stroma pH 8 and thylakoid lumen pH 4 c)stroma low 5 and thylakoid lumen high 8 d)stroma pH 4 and thylakoid lumen pH 7 9.The committed step of glycolysis is phosphofructokinase, which is inhibited by: a)high concentration of fructose 6-P b)high concentration of ADP c)high concentration of ATP d)high concentration of fructose 1,6-bisphosphate 10.What do carotenoid do in photosynthesis? a)they turn northern forests into spectacular display of yellow and orange. b)they extend the range of wavelengths that can drive photosynthesis. c)they can protect free radicals in photosynthesis. d)the pigment of light-dependent reactions use CO2 to make ATP. 11.If the light-independent reactions synthesize glucose, how can these be cyclic reactions? a)Because glucose is the first reactant in the cycle. b)Because glucose is part of the cycle. c)Glucose is synthesized as a side reaction but the reation intermediates are regenerated to complete a cycle. d)Glucose is another name for RuBP. 12.Maximum yield of ATP per molecule of glucose in cellular respiration is a)40 b)36 c)30 d)26 13.In prokaryotes, the components of the electron transport chain are located in the: a)inner membrane of mitochondria b)outer membrene of mitochondria c)in the cell membrane d)in the matrix of mitochondria 14._____________ reation converts NADP+ to NADPH. 15.Which of the estimate of chloroplast contained in one cell is reasonable? a)10-20 b)40-50 c)100-200 d)400-500 --
