2 f Respiration

Question 1

What is anaerobic respiration

Answer 1

Respiration with the lack of oxygen

Question 2

Waste products of aerobic respiration

Answer 2

Carbon dioxide & water

Question 3

What could ATP be used for

Answer 3

Chemical digestion, muscle contractions, keeping warm, active transport, passage of nerve impulses, growth

Question 4

Equation for aerobic respiration

Answer 4

Glucose + oxygen –> Carbon dioxide + water

Question 5

Symbol equation for aerobic respiration

Answer 5

C₆H₁₂O₆ + 6 O₂ –> 6 CO₂ + 6 H₂O

Question 6

Why anaerobic respiration produces less ATP

Answer 6

It involves incomplete breakdown of glucose

Question 7

Where anaerobic respiration usually takes place

Answer 7

Muscles

Question 8

When do we respire anaerobically

Answer 8

The body can only transport a certain amount of oxygen to the muscles so they’re unable to respire aerobically

Question 9

Ẃhat happens when there’s lactic acid build up

Answer 9

Lowers the Ph, denatures enzymes

Question 10

Why is there still energy stored in lactic acid

Answer 10

The glucose has not fully broken down

Question 11

How is lactic acid removed

Answer 11

Using oxygen to produce CO₂ and H₂O

Question 12

Word equation for anaerobic respiration in animals

Answer 12

Glucose –> lactic acid

Question 13

Waste products of anaerobic respiration in plants

Answer 13

Ethanol & CO₂

Question 14

Another name for anaerobic respiration in yeast

Answer 14

Fermentation

Question 15

Word equation for anaerobic respiration (plants)

Answer 15

Glucose –> Ethanol + CO₂

Question 16

What does cellular respiration release

Answer 16

energy from glucose

Question 17

Definition of aerobic respiration

Answer 17

Chemical reaction in cells that uses oxygen to breakdown nutrient molecules to release energy

Question 18

Definition of Anaerobic respiration

Answer 18

Chemical reaction in cells that breaks down nutrient molecules to release energy for use in cell processes

Question 19

What happens at high intensity exercise

Answer 19

Muscles need more energy, but the body can only transport a certain amount of oxygen

Question 20

What happens when oxygen runs out during exercise

Answer 20

Glucose is not fully broken down by it, so it produces lactic acid

Question 21

Anaerobic resp. produces … energy than aerobic resp.

Answer 21

Less

Question 22

Chemical equation for anaerobic respiration (animals)

Answer 22

C₆H₂O₆ –> 2 C₃H₆O₃

Question 23

Whats the amount of oxygen needed to breakdown lactic acid called

Answer 23

Oxygen dept

Question 24

Chemical equation for anaerobic respiration (plants)

Answer 24

C₆H₁₂O₆ –> 2 C₂H₅OH + 2 CO₂
