Photosynthesis Flashcards
What is the location and function of the light dependent reaction in photosynthesis?
Location: thylakoid membrane
Function: make ATP & reduced NAD
How is the electron excited and emitted in the light dependent reaction?
Light absorbed by chlorophyll in the thylakoid membrane of the chloroplast, causes photoionisation
How does the electron move down the electron transport chain
A series of redox reactions which cause the release of energy
What do the H+ ions do in the light dependent reaction
Pumped from stroma to inner thylakoid membrane by chemiosmosis
Diffuse back through ATP synthase to cause phosphorylation ADP+Pi=ATP
How is reduced NAD formed
NAD combines with e- and h+ to form reduced NADP
What is photoionisation
The process of light splitting up H2O to form H+ and E- and O2
What is the location and function of the light independent reaction
Location: Stroma
Function: Production of glucose for respiration & to make proteins and lipids
What combines to make GP (2x 3C) and what happens to GP
CO2 and RuBP (5C)
GP is reduced to TP
How many carbons are used to regenerate RuBP
5/6
1/6 is used to make glucose and other organic compounds
What organic compounds are made from GP (acids)
Fatty acids and amino acids
What organic compound does TP make
Glycerol
What’s the equation of photosynthesis
6CO2 + 6H2O —>
Reactants
C6H12O6 + 6O2
