Photosynthesis - 5.6

Question 1

What is the general equation for photosynthesis?

Answer 1

6CO2 + 6H2O + energy from photons = C6,H12,06 + 6O2

Question 2

What is the granum?

Answer 2

the inner part of chloroplast made from stacks of thylakoids

Question 3

What is the thylakoid?

Answer 3

flattened membrane bound sac found inside chloroplasts. This is where the light dependant stage of photosynthesis happens.

Question 4

What is the stroma?

Answer 4

The fluid filled matrix inside the chloroplast. This is where the light independent stage takes place.

Question 5

Where does the light dependant stage take place?

Answer 5

grana/ across thylakoid membrane

Question 6

What products from the LDS enter the Calvin Cyle?

Answer 6

1) NADPH

2) ATP

Question 7

What is the order of molecules in the calvin cycle starting from when CO2 is introduced?

Answer 7

GP –> TP –> RuBP

Question 8

How is glucose made in the calvin cycle?

Answer 8

Two TP molecules are required to make 1 molecule of Glucose.

1 out of every 6 molecules of TP are used to make Glucose.

This means it takes

Question 9

What are the total products the LDS?

Answer 9

• O2
• ATP
• NADPH

Question 10

What are the total products of cyclic photophosphorylation?

Answer 10

ATP

This is because the electrons move from the PS1 down the electron transport chain and back to PS1, without leaving to ferredoxin do reduce NADP.

Question 11

What is the name of the molecules in a photosystem that funnel the light energy to the chlorophyll?

Answer 11

Accessory pigments
