Energy Transfer in Organisms (Miss Reynolds)

Question 1

What does anaerobic respiration generate in terms of waste products?

Answer 1

Lactic acid in animals, ethanol in plants.

Question 2

Aerobic/anaerobic which is quicker?

Answer 2

Anaerobic is quicker.

Question 3

Aerobic/Anaerobic which is more efficient?

Answer 3

Aerobic

Question 4

Two key differences in the process of aerobic/anaerobic respiration.

Answer 4

Aerobic is complete breakdown of glucose while anaerobic is incomplete. Aerobic uses oxygen but anaerobic doesn’t.

Question 5

Where does glycolysis take place?

Answer 5

Cytoplasm

Question 6

Is glycolysis aerobic/anaerobic?

Answer 6

Anaerobic.

Question 7

Which enzyme catalyses synthesis of ATP?

Answer 7

ATPase.

Question 8

What are the phases of cellular respiration?

Answer 8

Glycolysis, link reaction, Krebs Cycle, electron transport chain.

Question 9

Biomass

Answer 9

Biological material derived from living or recently living organisms.

Question 10

Respiratory loss

Answer 10

The energy used by organisms for respiration.

Question 11

Name two examples of respiratory loss.

Answer 11

Active transport, movement and heat.

Question 12

Saprobionts

Answer 12

Bacteria/fungi that digest nutrients extracellularly.

Question 13

Natural Fertilisers

Answer 13

Contain nitrogen and phosphorus in organic compounds.

Question 14

Artificial Fertilisers

Answer 14

Inorganic chemical compounds that contain nitrogen and phosphorus.
