The light reactions take place in the structures of the chloroplast called the __________ while the Calvin cycle takes place in the ____________.
Occurs in the stroma
The calvin cycle which consumes the NADPH and ATP
CO2 in photosynthesis
O2 in photosynthesis
Sugar in photosynthesis
H2O in photosynthesis
Light in photosynthesis
Green light; because it is reflected by chlorophyll
What color light is the least effective in driving photosynthesis? Why?
When light strikes chlorophyll molecules, they lose electrons, which are ultimately replaced by splitting molecules of __________.
ATP and NADPH
Which of the following are produced by reactions that take place in the thylakoids and are consumed by reaction in the stroma?
The reactions of the Calvin Cycle require the outputs of the light reactions
The reactions of the Calvin cycle are not directly dependent on light and yet they usually do not occur at night. Why?
In hot, dry environments most plants close their stomata which saves water but decreases the amout of carbon deyoxide available inside the leaves.
Why is it difficult for most plants to carry out photosynthesis in very hot, dry environments such as deserts?
C4 and CAM can close their stomata and save water without shutting down photosynthesis
What is the eprimary advantage offered by C4 and CAM pathway?
Reactions that store energy by pumping H+ across membranes
What is comon to photosynthesis and cellular respiration?
