Photosynthesis: Site of the LDR Flashcards
1
Q
where does the LDR take place?
A
thylakoids of the chloroplasts
2
Q
what are thylakoids?
A
disc-like structures
3
Q
what is grana?
A
thylakoids that are stacked together in groups
4
Q
why do thylakoid membranes have a large surface area?
A
for the attachment of chlorophyll, electron carriers and enzymes that carry out the LDR
5
Q
what do the grana membranes have in them which catalyse the production of ATP?
A
ATP synthase channels
6
Q
what does the grana membrane being selectively permeable allow?
A
the creation of a proton (H⁺) gradient
7
Q
what 2 structures does the chloroplast contain that allows the quick and efficient manufacture of some proteins involved in the LDR?
A
- DNA
2. ribosomes
