|
what are the 3 parts in an ATP molecule? |
adenine, ribose, phosphate groups |
|
|
when is energy released from ATP ? |
when a phosphate is cut loose |
|
|
what gas is given off from a plant in bright sunlight at a temperature of 27 ℃? |
oxygen |
|
|
in the presence of sunlight, water and carbon dioxide are converted into what during photosynthesis? |
sugar & oxygen |
|
|
what are the reactants, meaning what is used in the overall reactions, in photosynthesis? |
water, carbon dioxide & sunlight energy |
|
|
in the overall equation for photosynthesis, 6 molecules of carbon dioxide result in 6 molecules of what? |
oxygen |
|
|
plants gather the suns energy with light-absorbing molecules called what? |
pigments |
|
|
which region of the visible spectrum is not absorbed well by chlorophyll? |
green region |
|
|
what is granum? |
a stack of thylakoids |
|
|
what is stroma and where is it located? |
stroma is gel like material between grana, the Calvin Cycle takes place here |
|
|
where in the chloroplast is chlorophyll found? |
thylakoid membrane |
|
|
where do the light-dependent reactions take place? |
in the stroma |
|
|
what are the products of the light-dependent reactions? |
ATP & NADPH |
|
|
what is the name of the step at the beginning of photosynthesis? |
light reactions |
|
|
what are all the steps in the light-dependent reactions? |
1) transfer of H+ from H2O is present 2) oxygen is released and the H+ bonds to NADP+ creating NADPH 3) ADP gains a phosphate group creating ATP |
|
|
list everything that is happening inside the thylakoid membrane. |
*light reactions take place here. *photo systems 1 and 2 are here. *photo system 1 contains different proteins and different chlorophyll pigments that allow different light absorptions. *photo system 2 absorbs light energy and ends up giving off energy as ATP. |
|
|
what is the pathway of flow of electrons during photosynthesis? |
H2O> NADPH+> Calvin Cycle |
|
|
where are photo systems 1 and 2 found? |
thylakoid membrane |
|
|
what is another name for the Calvin Cycle? |
light independent reactions |
|
|
where does the Calvin Cycle take place? |
in the stroma of chloroplasts |
|
|
what is a product of the Calvin Cycle? |
high-energy sugars |
|
|
how does the Calvin Cycle differ from the light-dependent reactions? |
the Calvin Cycle takes place in the stroma & light dependent reactions take place in the granum |
|
|
what do light-dependent reactions supply the Calvin Cycle with? |
ATP & NADPH |
|
|
what are the photosynthetic membranes inside chloroplasts called? |
thylakoids |
|
|
what happens to the rate of photosynthesis as the weather becomes very cold? |
the rate decreases |
|
|
what happens when a phosphate group is removed from an ATP molecule? |
ATP becomes ADP and energy is released |
|
|
write the overall equation for photosynthesis in both symbols and words... |
carbon dioxide + water ----sunlight---> glucose + oxygen 6CO2 + 6H2O ---sunlight---> C6H12O6 + 6O2 |
