Biology chapter 10 B

the calvin cycle…regenerates its starting material after molecules enter and leave the cycle

carbon fixation, reduction, regeneration… what are the three steps of the calvin cycle?

Rubisco…The most abundant enzyme in the world, central in photosynthesis, inefficient

ATP, NADH, G3P…what are the products of the calvin cycle?

stomata… where do the gas exchanges take place

stomata… On hot, dry days, plants close ________

O2…The closing of stomata reduces access to CO2 and causes what to build up?

photorespiration…limits damaging products of light reactions that build up in the absence of the Calvin cycle

it doesnt produce any sugar…why is photorespiration considered inefficient?

it doesnt do anything… what do C3 plants do to prevent photorespiration

C4 plants… what types of plants have the Kranz anatomy with bundle sheath cells

intense light, hight temperatures… what conditions do C4 plants thrive in?

open the stomata only at night… what do CAM plants do to deal with photorespiration

removes CO2 from the atmosphere… photosynthesis is the only natural process that does what?
