Respiration

Question 1

What is respiration?

Answer 1

It is the biochemical process in which the cells of an organism obtain energy by combining oxygen and glucose, resulting in the release of carbon dioxide,water and ATP.

Question 2

Why is energy needed?

Answer 2

For life processes such as:
Growth and repair
Movement
Control of body temperature in mammals

Question 3

What is aerobic respiration?

Answer 3

Glucose and oxygen react together in cells to produce carbon dioxide and water and releases energy in the form of ATP.

Question 4

What is anaerobic respiration?

Answer 4

Glucose breaks down without oxygen. This chemical reaction transfers energy from glucose to the cell. This reaction produces lactic acid rather than carbon dioxide and water.

Question 5

What is the equation for fermentation?

Answer 5

Glucose——> ethanol + carbon dioxide

Question 6

What are the steps of cellular respiration?(3)

Answer 6

• Glycosis
• Krebs cycle
• Electron transport

Question 7

Where does the second stage of cellular respiration take place within the mitochondria?

Answer 7

Within the matrix

Question 8

Where does the third stage of cellular respiration take place?

Answer 8

Takes place on the inner membrane

Question 9

How much ATP is produced from

cellular respiration?

Answer 9

38 ATP molecules

Question 10

How much ATP is produced from anaerobic respiration?

Answer 10

0 ATP molecules
