Flashcards in Photosynthesis Deck (12):
1

What is the location and function of the light dependent reaction in photosynthesis?

Location: thylakoid membrane
Function: make ATP & reduced NAD

2

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

3

How does the electron move down the electron transport chain

A series of redox reactions which cause the release of energy

4

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

5

How is reduced NAD formed

NAD combines with e- and h+ to form reduced NADP

6

What is photoionisation

The process of light splitting up H2O to form H+ and E- and O2

7

What is the location and function of the light independent reaction

Location: Stroma
Function: Production of glucose for respiration & to make proteins and lipids

8

What combines to make GP (2x 3C) and what happens to GP

CO2 and RuBP (5C)
GP is reduced to TP

9

How many carbons are used to regenerate RuBP

5/6
1/6 is used to make glucose and other organic compounds

10

What organic compounds are made from GP (acids)

Fatty acids and amino acids

11

What organic compound does TP make

Glycerol

12

What’s the equation of photosynthesis

6CO2 + 6H2O —>
Reactants

C6H12O6 + 6O2
