Flashcards in Photosynthesis: Site of the LDR Deck (7):
1

where does the LDR take place?

thylakoids of the chloroplasts

2

what are thylakoids?

disc-like structures

3

what is grana?

thylakoids that are stacked together in groups

4

why do thylakoid membranes have a large surface area?

for the attachment of chlorophyll, electron carriers and enzymes that carry out the LDR

5

what do the grana membranes have in them which catalyse the production of ATP?

ATP synthase channels

6

what does the grana membrane being selectively permeable allow?

the creation of a proton (H⁺) gradient

7

what 2 structures does the chloroplast contain that allows the quick and efficient manufacture of some proteins involved in the LDR?

1. DNA
2. ribosomes
