Aerobic And Anaerobic Respiration

Question 1

Is respiration endothermic or exothermic

Answer 1

It is exothermic

Question 2

Why is respiration an exothermic reaction

Answer 2

Because it releases energy from glucose molecules for use by the body

Question 3

Why do organisms need glucose molecules for energy

Answer 3

For chemical reactions to build larger molecules

For movement

To keep warm

Question 4

What is the aerobic respiration formula

Answer 4

Carbon dioxide and water = Glucose + oxygen

Question 5

What is the chemical name for glucose

Answer 5

C6 h12 o6

Question 6

In anaerobic respiration what is not completely broken down

Answer 6

The glucose molecules

Question 7

What does it mean if the group called molecules are not completely broken down and anaerobic respiration

Answer 7

This means that it transfers much less energy than aerobic respiration

Question 8

What is difference in anaerobic respiration between a plants and animals

Answer 8

While animals produce lactic acid plants and yeast produce ethanol and carbon dioxide

Question 9

What is another name for anaerobic respiration in yeast cells

Answer 9

Fermentation and can be used to produce bread and alcohol

Question 10

Why does the rate of respiration need to increase during exercise

Answer 10

The body demands more energy

Question 11

Why would anaerobic respiration take place

Answer 11

Because the muscles aren’t getting enough oxygen

Question 12

What does anaerobic respiration cause a build up of and what does it create

Answer 12

Anaerobic respiration causes a buildup of lactic acid and creates an oxygen debt

Question 13

How is oxygen debt paid?

Answer 13

your heart still beats very quickly after exercise for some time as the blood must be pumped on the body delivering oxygen to the muscles

Question 14

What is metabolism

Answer 14

Metabolism is the sum of all the chemical reactions in a cell or in the body

Question 15

What is the metabolism controlled by

Answer 15

The metabolism is controlled by enzymes and many need a transfer of energy

Answer 18

the formation of lipid molecules from a molecule of glycerol and 3 molecules of fatty acids

Question 19
