2 In photosynthesis, _?_ energy is converted to _?_ energy.

3 Light energy of the sun is converted into chemical energy in organic molecules.

4 What’s the formula of photosynthesis?

5 6CO 2 + 6H 2 O => C 6 H 12 O 6 + 6O 2

6 What are plant organelles responsible for photosynthesis? Where are they located?

7 Chloroplasts Located in mesophyll cells

8 What are the two major pigments within chloroplasts that are responsible for the colored hues we see in plants?

9 *Chlorophyll A & B = green *Carotenoids: carotene = orange and xanthophyll = yellow

10 What are main structures in the chloroplast? What are their functions?

11 * Thylakoid Disk: a flattened membrane sack inside chloroplast that is used to convert light energy to chemical energy *Lumen: interior space of thylakoid disks *Grana: columns of thylakoid disks *Stroma: thick fluid that surrounds Grana

12 What are the two parts (reactions) of photosynthesis?

13 *Part 1: light dependent reaction *Part 2: light independent reaction ( also called the Calvin cycle)

14 Describe light dependent reaction and light independent reaction

15 *Part 1: light dependent reaction requires light to provide the energy to start the process of breaking and making bonds. Breaks water into oxygen, hydrogen, and electrons. Makes ATP and NADPH. *Part 2: light independent reaction uses Calvin Cycle to make carbohydrates (sugar) for energy. Requires ATP and NADPH for energy.

16 Cyclic photophosphorylation of the light-dependent reaction occurs in which photosystem?

17 Photosystem I (P700)

18 How many turns of the Calvin cycle does it take to produce the 3-carbon molecules?

19 3 turns

20 Light delivers packets of energy called _?_ to Photosystem II (PS2)

21 Photons

22 Energy is absorbed and dispersed in a “domino effect” by the pigments in PS2 until it reaches PS2’s _?_

23 Reaction Center

24 ATP and NADPH products of Photosystem 1 are ready to enter the _?_

25 Calvin cycle (light- independent)
