1
Q

This molecule is usable energy for the cell.

A

ATP

2
Q

This is the equation for photosynthesis.

A

6H2O + 6CO2 –> 6O2 + C6H12O6

3
Q

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

A

Thylakoids

4
Q

This is is the gas required by the Calvin Cycle.

A

CO2 - it uses 6 molecules to produce 1 glucose.

5
Q

How is energy harvested from an ATP molecule?

A

A phosphate is removed, releasing usable energy.

6
Q

What type of energy drives photosynthesis?

A

Light Energy

7
Q

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

A

Chlorophyll

8
Q

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

A

Three 5-carbon molecules.

9
Q

These are the parts of an ATP molecule.

A

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

10
Q

These are the 2 main processes of photosynthesis.

A

Light Dependent Reactions and Calvin Cycle

11
Q

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

A

NADPH

12
Q

This is the main purpose of the Calvin Cycle.

A

To produce GLUCOSE as food for the plant.

13
Q

This is where usable energy stored in ATP is found?

A

In the bonds between the phosphates.

14
Q

This is the function of NADP+.

A

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

15
Q

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

A

ATP

NADPH.

16
Q

A stack of thylakoids is called this.

A

Granum

17
Q

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

A

High energy electrons from PS2.

18
Q

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

A

ATP drops of 1 phosphate.

NADPH drops off 2 e- & 1 H+

19
Q

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

A

Stroma

20
Q

This molecule replenishes the electrons missing from PS2.

A

Water

21
Q

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

A

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

22
Q

These are the 2 reactants of photosynthesis.

A

6 CO2 and 6 H2O

23
Q

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

A

ATP synthase.

24
Q

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

A

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

25
Q

These are the products of photosynthesis.

A

6O2 and C6H12O6 (glucose)

26
Q

These are the 3 products of the Light Dependent Reactions.

A

ATP
NADPH
O2

27
Q

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

A

TWO

28
Q

This is the purpose of the Light Dependent Reactions.

A

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

29
Q

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

A

NADP+, ADP, and P

30
Q

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

A
  1. Active transport of H+ by the pumps

2. Water splitting apart.
