Calvin

Photorespiration…limits damaging products of light reactions that build up in the absence of the ________ cycle.

calvin

The ________ cycle…regenerates its starting material after molecules enter and leave the cycle.

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?

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, high 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?
