Respiration

Question 1

Give 3 uses of energy in organisms

Answer 1

-Muscle contration
-Protein synthesis
-Active transport

Question 2

Define aerobic respiration

Answer 2

Chemical reactions that use oxygen to break down nutrient molecules to release energy

Question 3

State the balanced equation for aerobic respiration

Answer 3

C6H12O6 + 6O2 → 6CO2 + 6H2O

Question 3

State the word equation for aerobic respiration

Answer 3

Glucose + Oxygen –> Carbon Dioxide + Water

Question 4

Define Anaerobic respiration

Answer 4

Chemical reactions that use oxygen to break down nutrient molecules to release energy without using oxygen

Question 5

What is the word equation for anaerobic respiration?

Answer 5

Glucose –> alcohol + carbon dioxide

Question 6

What is the word equation for anaerobic respiration during vigorous exercise?

Answer 6

Glucose –> Lactic acid

Question 7

State the balanced equation for anaerobic respiration

Answer 7

C6H12O6 → 2C2 H5 OH + 2CO2

Question 8

What happens to lactic acid during vigorous exercise?

Answer 8

It builds up in muscles and blood, causing an oxygen debt

Question 9

How is the oxygen debt removed after exercise?

Answer 9

After an exercise, the fast heart rate continues to transport the lactic acid in the blood from the muscles to the liver.
Deeper and faster breaths are continued for the lactic acid to be broken down
Once the lactic acid reaches the liver, it is broken down by the glucose.
