photosynthesis in details Flashcards
where does LDR (light dependent reaction) happen?
in thylakoid membrane
what is another name for LIR
Calvin cycle
what are the 2 light-harvesting systems called?
photosystem I and photosystem II
what type of photophosphorylation involves; PSI, PSII, 2 ?
non-cyclic photophosphorylation
what process breaks down water molecules ?
photolysis
where does photolysis occur?
in the thylakoid lumen
what is the broken down water molecule used for?
- the hydrogen ions are used to reduce NADP+ to NADPH
- the electrons replace the electrons that left PSII
- the oxygen is released as waste
what is produced during LDR?
ATP and NADPH
how does ATP synthase change ADP to ATP?
by adding a phosphate group to ADP
where does the LIR occur?
in the stroma of the chloroplast
what is the main role of LIR?
to reduce CO2 to form carbohydrates
RuBP and CO2 create an unstable 6-carbon molecule that breaks down into what?
2 GP or glycerate 3-phosphate
how is GP turned into TP?
when ATP and NADPH reduce the GP from the LDR, this forms 2 TP molecules
what is TP used for ?
to make amino acids, lipids, or carbohydrates
