Plants Flashcards
Where does Photosynthesis happen
In the thylakoid membranes of the chloroplast
What are the 2 stages of Photosynthesis
Light dependent reaction
Light independent reaction
What energy does photosystem 1 have
P700
What energy does photosystem 2 have
P680
What does the photolysis of water produce
2 H+ (protons)
½ O2
Which photosystem do electrons enter (comes first)
Photosystem 2
What is the process to make ATP in Photosynthesis called
Photophosphorylation
What causes photolysis to happen
Light gives it the energy
What does light do to the electrons in the chlorophyll
Excite them
Where do the H+ move in the electron transport chain
From the stroma to inside the thylakoid
Hoe do the H+get back into the stroma in the electron transport chain
Through the enzyme ATP synthase
Where do the electrons (and a proton) go after photosystem 1
To turn NADP into NADPH
What enters the Calvin cycle (plants breathe it)
CO2
What does the CO2 bind to in the Calvin cycle
Ribulose bisphosphate (RuBP)
How many carbons does ribulose bisphosphate (RuBP) have
5
What catalysed the reason between CO2 and ribulose bisphosphate (RuBP)
Rubisco
What does CO2 and a ribulose bisphosphate (RuBP) make
2x glycerate 3-phosphate (GP)
How many carbons does Glycerate 3-phospgate (GP) have
3
What does glycerate 3-phosphate turn into in the Calvin cycle
Triose phosphate (TP)
How many carbons does triose phosphate (TP) have
3
What reactions happen to turn GP into TP
2x ATP=ADP+Pi
2x NADPH=NADP
How much of triose phosphate (TP) become ribulose bisphosphate (RuBP)
⅚
What reaction happens to split triose phosphate (TP)
ATP=ADP+Pi
What does the other ⅙ create from TP (Calvin cycle)
Orangic molecules
