ch6/7 photosynthesis Flashcards
where is the thylakoid located in?
inner membrane of chloroplast
in the process, what is sunlight converted to?
ATP
what is ATP used to convert?
CO2
what is CO2 converted into
C6H12O6
what do chloroplast absorb?
sunlight
chlorophyll and other pigments are grouped into what?
photosystems in the chloroplast
when photosystems absorb light, what happens to their electrons?
they get excited
where do excited e- go through?
the electron transport chain (ETC)
sum up part 1
- sunlight is absorbed by the photosystems
- electrons get excited; they move down the inner membrane
- water gets split
sum up part 2
- electrons give energy to proton pumps
- protons (H+) are pushed to one side of the membrane
- this causes a concentration gradient (build up of H+)
what is a concentration gradient?
build up of protons (H+)
sum up part 3
- protons pass through ATP synthase
- ATP is made
what does ETC stand for?
electron transport chain
what is ATP synthase?
the enzyme that can add ADP + P to make ATP
in act 2, what is inorganic carbon dioxide converted into?
organic glucose
what is organic glucose equal to in act 2?
carbon fixation
what is stomata
pores on the outside of a leaf
what is the input in the calvin cycle?
carbon dioxide
what is the output in the calvin cycle?
glucose
what are three factors that influence photosynthesis?
- light intensity
- carbon dioxide
- temperature
photosystems are also
chlorophyll??
where is the stroma located in?
in the general space of the chloroplasts
