Ch 8 Review - Photosynthesis

What is the initial source of electrons for the photosynthetic electron transport chain?

• CO2

• H20

• O2

• Chlorophyll a

• Photons

In the chloroplast, light energy is absorbed by:

• H2O

• photons in the thylakoid membrane

• pigments in the stroma

• pigments in the thylakoid membrane

According to this graph, what color is absorbed most by pigments in the chloroplast?

• red

• orange

• green

• blue

What are the reactants for photosynthesis?

• CO2 and O2

• CO2 and H2O

• O2 and glucose

• CO2 and glucose

In the reaction center of photosystem I, chlorophyll a replaces missing electrons by:

H20 -> 2H+ + ½ O2

• reducing oxygen

• oxidizing oxygen

• reducing water

• oxidizing water

Where in the chloroplast is the NADPH and ATP produced by the photosynthetic ETC?

• thylakoid membranes

• stroma

• intermembrane space

• thylakoid lumen

The Calvin cycle is located in the:

• thylakoid membrane

• thylakoid lumen

• stroma

• cytoplasm

The initial organic molecule that is the reactant at the first step of the Calvin cycle is:

• CO2

• Rubisco

• RuBP

• G3P

How many "turns" of the Calvin Cycle does it take to make one 3-carbon G3P molecule?

• 1

• 3

• 4

• 6

After the Calvin cycle, what happens to NADP+ and ADP?

• They move to the mitochondria

• They are immediately reused in the Calvin cycle

• They move to the thylakoids to participate in the light-dependent reactions

• They are broken down by lysosomes
