|
chloroplasts contain saclike photosynthetic membranes called ____
|
thylakoids
|
|
|
what is a granum?
|
stack of thylakoids
|
|
|
the region outside the thylakoid membranes in the chloroplasts is called the ____
|
stroma
|
|
|
what're the 2 stages?
|
LDR and LIR
|
|
|
how does NADP+ become NADPH?
|
when NADP+ accepts a pair of electrons, energizing it into NADPH
|
|
|
what's the carrier molecule involved?
|
NADP+
|
|
|
in LDR, electrons move through the electron transport chain from ____ to ____
|
photosystem II to photosystem I
|
|
|
when does photosynthesis begin?
|
when pigments in photosystem II absorb light
|
|
|
how does ATP synthase produce ATp?
|
H+ ions move through it and their energy is used to convert ADP into ATP
|
|
|
what does the calvin cycle use to produce sugar?
|
ATP and NADPH
|
|
|
why are the reactions of the calvin cycle also called the LIR?
|
doesn't require light
|
|
|
energy from ____ and electrons from ____ are used to convert #____-____ molecules into ____-____ forms
|
ATP, NADPH, 3-carbon, higher-energy
|
|
|
what are the three factors that affect the rate at which photosynthesis occurs?
|
water
temperature light |
|
|
T or F
increasing the intensity of light decreases the rate of P |
False
|
|
|
the difference in charages across the thylakoid membrane provides what?
|
energy to make ATP
|
|
|
the ____ ____ uses six molecules of ____ to produce a single #____-carbon ____ molecule
|
calvin cycle, CO2, 6, sugar
|
