Photosynthesis

Question 1

This molecule is usable energy for the cell.

Answer 1

ATP

Question 2

This is the equation for photosynthesis.

Answer 2

6H2O + 6CO2 –> 6O2 + C6H12O6

Question 3

This is the name of the discs inside the chloroplasts where light is absorbed.

Answer 3

Thylakoids

Question 4

This is is the gas required by the Calvin Cycle.

Answer 4

CO2 - it uses 6 molecules to produce 1 glucose.

Question 5

How is energy harvested from an ATP molecule?

Answer 5

A phosphate is removed, releasing usable energy.

Question 6

What type of energy drives photosynthesis?

Answer 6

Light Energy

Question 7

This is the name of the molecule found in both PS1 and PS2 that absorbs light.

Answer 7

Chlorophyll

Question 8

This is the starting material for the Calvin Cycle that is recycled to the stroma after each turn of the cycle.

Answer 8

Three 5-carbon molecules.

Question 9

These are the parts of an ATP molecule.

Answer 9

Adenine (a nitrogen base)
Ribose (sugar)
3 phosphates

Question 10

These are the 2 main processes of photosynthesis.

Answer 10

Light Dependent Reactions and Calvin Cycle

Question 11

This molecule is produced using 2 high energy electrons released by PS1.

Answer 11

NADPH

Question 12

This is the main purpose of the Calvin Cycle.

Answer 12

To produce GLUCOSE as food for the plant.

Question 13

This is where usable energy stored in ATP is found?

Answer 13

In the bonds between the phosphates.

Question 14

This is the function of NADP+.

Answer 14

Electron Carrier: It carries 2 electrons and 1 H+.

Question 15

These are 2 high energy molecules that are fuel for the Calvin Cycle.

Answer 15

ATP

NADPH.

Question 16

A stack of thylakoids is called this.

Answer 16

Granum

Question 17

These turn on pumps that actively transport H+ into a thylakoid.

Answer 17

High energy electrons from PS2.

Question 18

What do ATP & NADPH drop off in the Calvin Cycle?

Answer 18

ATP drops of 1 phosphate.

NADPH drops off 2 e- & 1 H+

Question 19

This is the filling inside the chloroplast that surrounds stacks of thylakoids.

Answer 19

Stroma

Question 20

This molecule replenishes the electrons missing from PS2.

Answer 20

Water

Question 21

How many molecules break away from the group of modified molecules during each turn of the Calvin Cycle?

Answer 21

1 group will break away to eventually become glucose. The other 5 get recycled back into the starting material.

Question 22

These are the 2 reactants of photosynthesis.

Answer 22

6 CO2 and 6 H2O

Question 23

This is the name of the enzyme where facilitated diffusion occurs in a thylakoid.

Answer 23

ATP synthase.

Question 24

This is how many ATPs are used each turn of the Calvin Cycle.

Answer 24

NINE - 6 to modify the molecules with phosphates and 3 more to recycle the molecules back to the original starting material.

Question 25

These are the products of photosynthesis.

Answer 25

6O2 and C6H12O6 (glucose)

Question 26

These are the 3 products of the Light Dependent Reactions.

Answer 26

ATP
NADPH
O2

Question 27

This is how many turns the Calvin Cycle must make in order to produce 1 complete glucose molecule.

Answer 27

TWO

Question 28

This is the purpose of the Light Dependent Reactions.

Answer 28

To produce fuel molecules (ATP & NADPH) for the Calvin Cycle and to produce O2 for the atmosphere.

Question 29

These are the material the Calvin Cycle sends back to the LDR to get recharged.

Answer 29

NADP+, ADP, and P

Question 30

These 2 events cause H+ to build up in the thylakoid.

Answer 30

1. Active transport of H+ by the pumps

2. Water splitting apart.
