B12 Respiration

Question 1

What are the 6 uses of Energy in living organisms?

Answer 1

Muscle contraction, protein synthesis, cell devision, growth, passage of nerve impulses, maintenance of a constant body temperature

Question 2

What is Aerobic Respiration?

Answer 2

The chemical reaction in cells that use oxygen to break down nutrient molecules to release energy

Question 3

What is the word equation for aerobic respiration?

Answer 3

Glucose + Oxygen —> Carbon dioxide + Water

Question 4

Balanced symbol for aerobic respiration

Answer 4

C6H12O6 + 6O2 —> 6CO2 + 6H2O

Question 5

What is Anaerobic Respiration?

Answer 5

The chemical reaction in cells that break down nutrient molecules to release energy without using oxygen

Question 6

Is aerobic or anaerobic respiration more effective?

Answer 6

Aerobic is a lot more effective than anaerobic respiration because aerobic respiration releases much more energy per glucose molecule than anaerobic respiration

Question 7

Anaerobic Respiration word equation

Answer 7

Glucose —-> Lactic acid

Question 8

What causes oxygen debt?

Answer 8

lactic acid builds up in muscles during vigorous exercise causing an oxygen debt

Question 9

How is oxygen debt removed?

Answer 9

• continuation of fast heart rate to transport lactic acid in the blood from the muscles to the liver
• continuation of deeper and faster breathing to supply oxygen for aerobic respiration of lactic acid

-aerobic respiration of lactic acid in the liver
