Flashcards in Photosynthesis Deck (30):
1

This molecule is usable energy for the cell.

ATP

2

This is the equation for photosynthesis.

6H2O + 6CO2 --> 6O2 + C6H12O6

3

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

Thylakoids

4

This is is the gas required by the Calvin Cycle.

CO2 - it uses 6 molecules to produce 1 glucose.

5

How is energy harvested from an ATP molecule?

A phosphate is removed, releasing usable energy.

6

What type of energy drives photosynthesis?

Light Energy

7

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

Chlorophyll

8

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

Three 5-carbon molecules.

9

These are the parts of an ATP molecule.

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

10

These are the 2 main processes of photosynthesis.

Light Dependent Reactions and Calvin Cycle

11

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

NADPH

12

This is the main purpose of the Calvin Cycle.

To produce GLUCOSE as food for the plant.

13

This is where usable energy stored in ATP is found?

In the bonds between the phosphates.

14

This is the function of NADP+.

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

15

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

ATP
NADPH.

16

A stack of thylakoids is called this.

Granum

17

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

High energy electrons from PS2.

18

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

ATP drops of 1 phosphate.
NADPH drops off 2 e- & 1 H+

19

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

Stroma

20

This molecule replenishes the electrons missing from PS2.

Water

21

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

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

22

These are the 2 reactants of photosynthesis.

6 CO2 and 6 H2O

23

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

ATP synthase.

24

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

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

25

These are the products of photosynthesis.

6O2 and C6H12O6 (glucose)

26

These are the 3 products of the Light Dependent Reactions.

ATP
NADPH
O2

27

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

TWO

28

This is the purpose of the Light Dependent Reactions.

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

29

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

NADP+, ADP, and P

30

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

1. Active transport of H+ by the pumps
2. Water splitting apart.
