Biology Chapter 8 Photosynthesis Test

Question 1

Organisms that obtain food by consuming other living things

Answer 1

Heterotrophs

Question 2

Organisms that make their own food

Answer 2

Autotrophs

Question 3

The process by which autotrophs use the energy of sunlight to produce high-energy carbohydrates that can be used as food

Answer 3

Photosynthesis

Question 4

The light absorbing molecules in a plant

Answer 4

Pigments

Question 5

The plant’s principle pigment

Answer 5

Chlorophyll

Question 6

These are found in a chloroplast, they are saclike photosynthetic membranes, their stacks are called grana

Answer 6

Thylakoids

Question 7

The fluid portion of the chloroplast which is outside of the thylakoid

Answer 7

Stroma

Question 8

An electron carrier that accepts a pair of high energy electrons and transfers them and their energy to another molecule

Answer 8

NADP+

Question 9

These kinds of reactions require light, they produce NADPH and ATP, takes place in the thylakoid membrane

Answer 9

Light dependent reactions

Question 10

These reactions do not require light, they produce sugars by the combination of carbon dioxide and ATP/NADPH

Answer 10

Light independent reactions

Question 11

These are found in the thylakoid membrane, they are clusters of chlorophyll and proteins

Answer 11

Photosystems

Question 12

This transports high energy electrons during ATP- generating reactions

Answer 12

Electron transport chain

Question 13

This protein allows H+ ions to be shuttled out of the thylakoid lumen, it is powered by the gradient, it creates ATP

Answer 13

ATP synthase

Question 14

Nickname for light independent reactions

Answer 14

The Calvin Cycle

Question 15

One of the most important compounds that cells use to store and release energy

Answer 15

ATP
