B9 - Respiration

Question 1

Aerobic Respiration

Answer 1

Breathing in Oxygen, Glucose reacts with Oxygen to transfer energy to the Cells, Exothermic Reaction

Question 2

Anaerobic Respiration

Answer 2

Increase heart rate and body cant provide with enough Oxygen, releases less energy by using Latic Acid, takes place without Oxygen,

Question 3

Latic Acid

Answer 3

Built up when body has shortage of Oxygen

Question 4

Chemical Equation for Anaerobic Respiration

Answer 4

Glucose (C.6 H.12 0.6) –> Latic Acid (2 C.3 H.6 O.3)

Question 5

Equation for Latic Acid Removal

Answer 5

Lactic Acid + Oxygen –> Water + Carbon Dioxide

Question 6

Oxygen Debt

Answer 6

• Amount of Oxygen needed to reduce Latic Acid

- Muscle Fatigue occurs during Oxygen Debt

Question 7

Use of Yeast

Answer 7

Yeast used to puff up bread or make beverage

Question 8

Muscle Contraction

Answer 8

Happens all the time as your body always moves, requires energy, more energy if they contract faster

Question 9

Occurrences during Exercise

Answer 9

• Increase heart rate/blood flow
• Increase breathing rate
• Glycogen stored in Muscles convert back to Glucose

Question 10

Mitochondria

Answer 10

Area of respiration, amount of Mitochondria shows how active the cell is

Question 11

Respiration on different temperatures

Answer 11

• For some Mammals, energy transferred from respiration keep you warm, on a cold day
• On hot days, you sweat which releases heat from the body

Question 12

Cellular Respiration

Answer 12

When cells break down food molecules for more energy due to muscle contraction

Question 13

Unhealthy vs Healthy Body

Answer 13

• Unhealthy have less around of blood pumped out each beat
• Healthy people have more volume in their heart
• Unhealthy have faster pulse rate

Question 14

Muscle Fatigue

Answer 14

When muscles stop contracting, maybe due to amount of Lactic Acid in the muscle produced by Anaerobic Respiration

Question 15

Anaerobic Respiration in Plants

Answer 15

Instead of producing Lactic Acid, the produce Ethanol and Carbon Dioxide

Question 16

Metabolism

Answer 16

Sum of all reaction taken place in the body, some energy transferred to environment

Question 17

Metabolic Reaction

Answer 17

• Glucose to Starch, Glycogen, Cellulose
• Reactions of Respiration and Photosynthesis
• Lipid Molecules formed Glycerol and Fatty Acids
• Breakdown of Protein in Liver to form Urea to be extracted by Kidneys

Question 18

Lactic Acid Removal

Answer 18

When Oxygen reacts with Lactic Acid, forms Carbon Dioxide and Water, removed in the Liver

Question 19

Respiration

Answer 19

Using Glucose in your body to cause chemical reactions

Question 20

Anaerobic Respiration in Muscles

Answer 20

Produce Lactic Acid, NOT Ethanol

Question 21

Where does respiration take place

Answer 21

In every living cell

Question 22

How do reactants of respiration get into animal cells

Answer 22

Diffusion in the capillaries

Question 23

Chemical Equation for Aerobic Respiration

Answer 23

Glucose (C.6 H.12 O.6) + Oxygen (6O.2) —> Carbon Dioxide (6C O.2) + Water (6H.2 O) + energy

Question 24

Respiration During Exercise

Answer 24

• Increased Breathing Rate
• Increased Breathing Volume
• Increased Blood flow to muscles
• Increased Heat Rate

Question 25

Respiration during Vigorous Exercise

Answer 25

• Insufficient Oxygen amount, Oxygen Debt
• Lactic Acid forms
• Sweating and Increase of Body Temperature
