Chapter 10: Photosynthesis

Question 1

Sustain themselves without eating anything derived from other organisms

Answer 1

Autotrophs

Question 2

Live on compounds produced by other organisms

Answer 2

Heterotrophs

Question 3

Light reactions produce:

Answer 3

ATP, NADPH, O2 (waste product)

Question 4

The three phases of the Calvin Cycle

Answer 4

Fixation, Reduction, Regeneration

Question 5

Fixation

Answer 5

CO2 combines with ribulose bisphosphate (RuBP)

Question 6

Reduction

Answer 6

ATP and NADPH are used to reduce the sugar; one G3P comes off to form a sugar

Question 7

Regeneration

Answer 7

The other five G3P continue on in the cycle to regenerate ribulose bisphosphate

Question 8

Light Reactions

Answer 8

Use light from the sun to produce ATP and NADPH

Question 9

Dark Reactions

Answer 9

Fix CO2 to produce a sugar

Question 10

Photosynthesis equation

Answer 10

6CO2 + 12H2O + Light energy –> C6H12O6 + 6O2 + 6H2O

Question 11

The process that converts solar energy into chemical energy

Answer 11

Photosynthesis

Question 12

Absorbs purple and red light; reflects green light

Answer 12

Chlorophyll A

Question 13

Enzyme that joins ribulose bisphosphate and CO2 in fixation

Answer 13

Rubisco

Question 14

Where does the Calvin Cycle take place?

Answer 14

Stroma

Question 15

Where are ATP and NADPH made?

Answer 15

Stroma

Question 16

Where do the photosystems take place?

Answer 16

Thylakoid membrane

Question 17

When oxygen in released as a result of photosynthesis, it is a by-product of what?

Answer 17

Splitting the water molecules

Question 18

Oxidation

Answer 18

Loss of an electron

Question 19

Reduction

Answer 19

Gaining of an electron

Question 20

Are humans autotrophs or heterotrophs?

Answer 20

Heterotrophs
