Photosynthesis

Question 1

ATP

Answer 1

Adenosine Triphosphate, high energy molecule

Question 2

ADP

Answer 2

Adenosine Diphosphate, low energy molecule.

Question 3

What happens in Pathway 1?

Answer 3

Energised electrons are transferred from carrier to carrier/ energy released/ ATP produced from ADP and P/ electron returns to the chlorophyll.

Question 4

What happens in Pathway 2?

Answer 4

Electron transferred to NADP+/ water is split into protons, electrons and oxygen/NADP+ joins with 2 electrons and one proton to form NADPH.

Question 5

What happens in the Dark Stage?

Answer 5

NADPH supplies protons and electrons/ carbon dioxide is converted to glucose/ATP supplies energy/ ADP returns to light stage/

Question 6

Products of the light stage

Answer 6

ATP, NADPH, O2.

Question 7

Dark Stage products

Answer 7

Glucose, ADP, Phosphate, NADP+.

Question 8

Dark stage reactions are controlled by..?

Answer 8

Enzymes -> means its temperature dependent.

Question 9

Photosynthesis equation

Answer 9

6H2O+ 6CO2 = C6H12O12 + 6O2
