Respiration Details

Question 1

Uses of energy in living organisms

Answer 1

-Muscle contraction
-Protein synthesis
-Cell division
-Growth
-Passage of nerve impulses
-Maintenance of constant body temperature

Question 2

Word equation for aerobic respiration

Answer 2

Glucose + Oxygen → Carbon Dioxide + Water

Question 3

Chemical equation for aerobic respiration

Answer 3

C₆H₁₂O₆ + 6O₂ → 6CO₂ + 6H₂O

Question 4

(Compared to aerobic respiration)Per glucose molecule, anaerobic respiration releases(in terms of energy)…

Answer 4

less energy than aerobic respiration

Question 5

Word equation for anaerobic respiration in yeast

Answer 5

Glucose → Alcohol + Carbon Dioxide

Question 6

Word equation for anaerobic respiration in muscles during vigorous exercise

Answer 6

Glucose → Lactic acid

Question 7

Chemical equation for anaerobic respiration in yeast

Answer 7

C₆H₁₂O₆ → 2C₂H₅OH + 2CO₂

Question 8

Cause of oxygen debt

Answer 8

The build up of lactic acid in muscles and blood during vigorous exercise

Question 9

Ways in which oxygen debt is 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

Question 10

Effect on temperature on respiration in yeast

Answer 10

When temperature increases, the rate of respiration also increases
