Cell Respiration

Question 1

What is respiration?

Answer 1

Breathing in and out

Question 2

What does respiration do?

Answer 2

Supplies oxygen to the body’s cells & takes away poisonous by-product (carbon dioxide)

Question 3

What is cell respiration?

Answer 3

Different body cells have different respirations & it is called Cell Respiration

Question 4

What is movement caused by and what does it need

Answer 4

Muscle Contracting which needs Energy

Question 5

What does your muscles obtain energy from?

Answer 5

Food

Question 6

What makes up food

Answer 6

Carbohydrates
Proteins
Fats
Vitamins
Minerals
Fibre

Question 7

What is the break down of food called ?

Answer 7

Digestion

Question 8

What does your body use for energy?

Answer 8

Carbohydrates and fats

Question 9

How are carbohydrates digested

Answer 9

Some glucose is stored in your Liver as
‘glycogen’ & is released when the level of glucose in the blood becomes low

Some glucose is stored in the Muscles as ‘glycogen’ & is converted back to glucose and is used during exercise

Question 10

What is the difference between
Aerobic & Anaerobic
Respiration

Answer 10

Muscle fibers obtain energy from glucose.

When the process USES oxygen it is called
Aerobic Respiration .

When it DOES NOT use oxygen it is called
Anaerobic Respiration.

Question 11

How does Aerobic Respiration work?

Answer 11

glucose + oxygen -> carbon dioxide + water + energy

Question 12

What is Aerobic Respiration used for?

Answer 12

Produces heat therefore warming the body

Used for muscle contraction providing movement

Question 13

What are the advantages of Aerobic Respiration

Answer 13

A lot of glucose is stored so it can supply energy for long periods of time

There are no dangerous by-products

Question 14

What are the disadvantages of
Aerobic Respiration

Answer 14

Take 90 seconds for the Aerobic system to fully work

Activities require maximum effort

In activities requiring maximum effort oxygen cannot get to our muscles in time.

Question 15

What is Anaerobic Respiration used for

Answer 15

During maximum effort, oxygen cannot reach the muscles fast enough so we use anaerobic respiration.

Question 16

How does Anaerobic Respiration work?

Answer 16

glucose —> energy + lactic acid

The same amount of glucose produces less energy but at a faster rate

Question 17

What is a advantage of Anaerobic
Respiration ?

Answer 17

Can be used immediately & for powerful contractions

Question 18

What is a disadvantage of Anaerobic Respiration ?

Answer 18

After 60-90 seconds, lactic acids make muscles tired & painful. Creating Oxygen debt.

Question 19

What is Oxygen Debt?

Answer 19

The amount of oxygen needed to get the body back to its resting state

Question 20

What happens to Lactic Acid?

Answer 20

It is turned into carbon dioxide and water and a little back into glucose when enough oxygen is available

Question 21

How is Oxygen Dept created?

Answer 21

By taking part in maximum-effort activities that require sudden a burst of speed and while waiting for your heart rate & breathing to increase during long events

Question 22

What is aerobic respiration

Answer 22

Aerobic respiration is the production of energy with using oxygen

Question 23

What is anaerobic respiration?

Answer 23

The production of energy without using oxygen
