why is ATP important?
it provides cellular energy
how is energy released from ATP?
when the bond between the phosphate groups are broken
in photosynthesis,_______ energy is converted into _______ energy.
solar, chemical
what is the overall equation for photosynthesis?
CO2 + H2O -----> C6H12O6 + O2
what are three ingredients that are necessary for photosynthesis to occur?
carbon dioxide, water, and sunlight
where in a plant cell does photosynthesis occur?
chloroplasts
what is the fluid that surrounds the Grana called?
stroma
what are thylakoids stacked on one another called?
Grana
what is a single "pancake" called?
thylakoid
where are most organelles located in the plant?
leaves
where are the light reactions located
thylakoid membrane
what are the reactants in light reactions?
sunlight and water
what are the products of the light reactions?
ATP, NADPH, and oxygen
what is chemiosmosis
how ATP is produced
where is the Calvin cycle located?
in the stroma
what are the reactants of the Calvin cycle?
ATP, NADPH, CO2
what are the products of the Calvin cycle?
glucose, RuBP
what is light intensity?
we're all available electrons are excited and no more will be released.
what are carbon dioxide levels?
only so much carbon dioxide can enter the carbon cycle
what is temperature?
plants will close their stomata to prevent water loss, but this then also prevents carbon dioxide from entering
what occurs in the process of photosynthesis?
light energy is converted into chemical energy
what does photosynthesis require in addition to water and carbon dioxide?
sunlight
what is the principal pigment of plants?
chlorophyll
what colors are visible spectrum in which chlorophyll absorbs light very well?
blue and red
chloroplasts contain sac-like photosynthetic membranes called
thylakoid
what is a granum?
a stack of thylakoids
what are two stages of photosynthesis called?
light reactions and Calvin cycle
NADP+ is involved in the ________ molecule in photosynthesis
carrier
how does NADP+ become NADPH?
it gets the age from the light reaction cycle, he accepts electrons
where do the light-dependent reactions take place?
thylakoid membrane
what happens to water in the light reactions?
it's broken down into hydrogen, oxygen, and e-
why is the leaf the main organ in photosynthesis?
because everything occur is in there such as the chloroplast and the Calvin cycle
what organelle is necessary for photosynthesis to occur?
chloroplast
what is the pigment that is needed to absorb light energy?
chlorophyll
what is the stoma and why is it important in the process of photosynthesis?
the stoma is the opening in the leaf, it is important because it releases water in oxygen to bring in carbon dioxide.
what are the cells in the leaf called?
mesophyll
both photosystem 1 and photosystem 2 donate what?
they donate electrons to a transport chain that generates NADPH
if most of G3P is converted back into RuBP what happens to the rest of it?
it produces glucose
