1.

Photosynthesis is the production of carbon compounds in cells using (a) energy

2.

Summarize the light dependent reaction

a)

Reactions in the cell that use the cytoplasm to capture light energy in order to create ATP

b)

Reactions in the cell that use cristae to capture light energy to be converted into chemical energy like ATP

c)

Reactions in the cell that use chlorophyll to capture energy in the form of glucose to be converted into CO2

d)

Reactions in the cell that use chlorophyll to capture light energy to be converted into chemical energy such as ATP.

3.

Explain what occurs in the light dependent reaction step by step

a)

Red and blue light hit the thylakoid, chlorophyll molecules absorb it and cause movement, enzyme rips water apart, H's and electrons are ripped off of water, leaving Oxygen alone which floats out Electrons and protons go through a process similar to the ETC, ATP synthase generates ATP. NADPH picks up the electrons and protons at the end (Light and water yeild oxygen, atp, and NADPH)

b)

CO2 diffuses into the stroma of the chloroplast. Enzymes turn CO2 into glucose. These enzymes use two things made over in the light dependent reaction: ATP and NADPH. (CO2 goes in, glucose is produced)

4.

What are the byproducts of the light dependent reaction?

a)

Oxygen

b)

ATP

c)

NADPH

d)

CO2

5.

Where in a chloroplast does the light dependent reaction occur?

a)

Stroma

b)

Cytoplasm

c)

Nucleus

d)

Thylakoid

6.

Where in a chloroplast does the light independent reaction occur?

a)

Stroma

b)

Golgi

c)

Thylakoid

d)

Cytoplasm

7.

Summarize light independent reactions

a)

Biochemical reactions that require light to form organic materials. Glucose goes in and CO2 is produced. It occurs in the thylakoid.

b)

Biochemical reactions that don't require light to form organic materials. Carbon dioxide goes in and glucose is produced. It occurs in the stroma.

8.

Explain the steps involved in the light independent reaction.

a)

Red and blue light hit the thylakoid, chlorophyll molecules absorb it and cause movement, enzyme rips water apart, H's and electrons are ripped off of water, leaving Oxygen alone which floats out Electrons and protons go through a process similar to the ETC, ATP synthase generates ATP. NADPH picks up the electrons and protons at the end (Light and water yeild oxygen, atp, and NADPH)

b)

CO2 diffuses into the stroma of the chloroplast. Enzymes turn CO2 into glucose. These enzymes use two things made over in the light dependent reaction: ATP and NADPH. (CO2 goes in, glucose is produced)

(a)

12.

Outline the differences in absorption of red, blue, and green light by chlorophyll

a)
