Photosynthesis Flashcards
1
Q
LDR?
A
- photosynthetic pigments e.g. chlorophyll a absorb light energy
- excite electron which leaves chlorophyll (photoionisation)
- electrons at higher energy level
- electrons move along ETC
- electrons release energy
- energy used to join ADP and Pi = ATP
- NADP reduced = NADPH
- photolysis of water = H+, electrons and oxygen
2
Q
formula?
A
6CO2 + 6H20 + energy —> C6H1206 + 602
3
Q
where does LDR take place?
A
thylakoid membrane
4
Q
what does LDR use?
A
- light energy
- to make ATP and NADPH
5
Q
what does LIDR use?
A
- products of LDR
- to make useful organic comp
6
Q
where does LIDR take place?
A
stroma
7
Q
define organic?
A
compound that contains carbon
8
Q
define inorganic?
A
compound that doesnt contain carbon
9
Q
what are coenzymes?
A
non-protein molecules that help enzymes to work by transferring other mol around
10
Q
coenzymes in photosynthesis?
A
NADP
- transfers H mol around
11
Q
define phoshporylation?
A
adding phosphate group
12
Q
define photophosphorylation?
A
using light energy to add phosphate
13
Q
define photolysis?
A
using light energy to split molecules
14
Q
define ETC?
A
when electrons flow through proteins in membrane
15
Q
what does the chloroplast do?
A
absorbs light energy used for photosynthesis to make useful organic comp
