Chloroplasts Flashcards
(28 cards)
What Is The Stroma And What Does It Contain?
It is the thick fluid, similar to cyctoplasm, that contains ribosomes, ATP, enzymes used for respiration and the genome.
When starched together, what do thylakoids make?
Grana.
What happens at the grana?
They actively fix O2.
When grana are not fixing O2, what happens to their structure?
They disassemble.
Where might you find a chromoplast?
In a red pepper.
What kind of plastids to potatoes have?
Amyloplasts.
What are some plastids derived from?
Luecoplasts.
Do all chloroplasts come with the same structure?
No, their thylakoids can be differently structured.
Where are he stromal lamellae found?
They are the interconnecting sections between grana.
How do red algaes thylakoids appear?
They are flattened sacs, with one membrane only one layer think, with a granular surface, made of accessory pigments.
How many membranes do Dinoflagellate chloroplasts have?
3, they appear in a triples membrane, found in groups of 3 and are unappressed.
What are the two reactants of photosynthesis?
Water and CO2
What are he three products of photosynthesis?
Glucose, O2 and H2O
In photosynthesis does water gain or lose electrons?
Loses, it is oxidised.
How is photosynthesis endergonic?
It requires the energy from photons.
Where are chlorophyll molecules found?
In the thylakoids membrane.
What does chlorophyll a have attached to it?
A Methyl group.
What does Chlorophyll b have attached to it, instead of the methyl that is attached to chlorophyll a?
A CHO group.
Where do the light reactions of photosynthesis occur?
In the thylakoids
What is produced from the light reaction?
ATP, NADH and O2.
Where does the Calvin cycle occur?
In the stroma.
What is produced in the Calvin cycle?
O2 and GP3.
What is the photon in the light phase used to do?
Split a H2O molecule.
What is the name for photosystem 11’s and 1’s special pair?
P680 and P700, respectively.
