B9-Respiration

Question 1

Define aerobic respiration

Answer 1

Exothermic reaction that breaks down glucose to release energy using oxygen

Question 2

What kind of reaction is respiration?

Answer 2

Exothermic

Question 3

Give 1 importance of respiration

Answer 3

Metabolic reactions eg build, muscle contraction, maintaining body temp, active transport

Question 4

State 1 response of the body to exercise

Answer 4

Increase heart rate/breathing rate, glycogen converted to glucose, increase blood flow to muscles

Question 5

What happens to the glycogen stored in muscles when you exercise?

Answer 5

Converted into glucose for respiration

Question 6

What is anaerobic respiration?

Answer 6

Breakdown of glucose to release small amount of energy without the use of oxygen

Question 7

Name the toxic substance produced by anaerobic respiration

Answer 7

Lactic acid

Question 8

State an effect on your body after anaerobic respiration

Answer 8

Muscle fatigue

Question 9

Define oxygen debt

Answer 9

Amount of oxygen needed to break down lactic acid

Question 10

What do plants make in anaerobic respiration?

Answer 10

Ethanol and CO2

Question 11

Give 1 use of yeast doing anaerobic respiration

Answer 11

Making bread/alcohol

Question 12

Give 1 example of a metabolic reaction in cells

Answer 12

Convert glucose to glycogen, starch, cellulose/make lipids/proteins/respiration/photosynthesis/breakdown of proteins

Question 13

State a function of liver

Answer 13

Detoxification/breakdown of old blood cells/remove lactic acid(convert to glucose)
