Question 2

Process used by plants and other autotrophs to capture light energy and use it to power chemical reactions that convert carbon dioxide and water into oxygen and energy rich carbohydrates such as sugars and starches

Answer 2

Photosynthesis

Question 3

Light absorbing molecules used by plants to gather sun energy

Answer 3

Pigment

Question 4

Principal pigment of plants and other photosynthetic organisms

Answer 4

Chlorophyll

Question 5

Saclike photosynthetic membranes found in chloroplast

Answer 5

Thylakoid

Question 6

Fluid portion of the chloroplast; outside of the thylakoids

Answer 6

Stroma

Question 7

Carrier molecule that transfers, high energy electrons from chlorophyll to other molecules

Answer 7

NADP+ (nicotinamide adenine dinucleotide phosphate)

Question 8

Set of reactions in photosynthesis that use energy from light to produce ATP and NADPH

Answer 8

Light dependent reaction

Question 9

Set a reactions in photosynthesis that don’t require light; energy from ATP and NADPH is used to build high energy compounds such as sugar; also called the Calvin cycle

Answer 9

Light Independent reaction

Question 10

Cluster of chlorophyll and proteins found in thylakoids

Answer 10

Photosystem

Question 11

Series of electron carrier proteins that shuttle high energy electrons during ATP-generating reactions

Answer 11

Electron transport chain

Question 12

Cluster of proteins that span the thylakoid membrane and allow hydrogen atoms (H+) to pass through it

Answer 12

ATP sythase

Question 13

The light independent reactions of photosynthesis in which energy from ATP and NADPH is used to build high energy compound such as sugar

Answer 13

Calvin cycle
