B9.1 - Aerobic Respiration (Finished)

Question 1

What is respiration?

Answer 1

Respiration is the process of transferring energy from the breakdown of glucose which goes on in every cell

Question 2

Is respiration endothermic or exothermic?

Answer 2

Respiration is exothermic

Question 3

Give 3 examples of how organisms use the energy transferred by respiration?

Answer 3

• To build up larger molecules from smaller ones (e.g. proteins from amino acids)
• To allow muscles to contract (in animals)
• Keep body temperature steady in colder environments (mammals + birds)
• moving mineral ions by active transport from soil to roots in plants

Question 4

What is aerobic respiration?

Answer 4

Aerobic respiration is respiration using oxygen

Question 5

Why is aerobic respiration usually used to break down glucose?

Answer 5

It is the most efficient way to transfer energy from glucose

Question 6

Where do (most of) the reaction is aerobic respiration happen?

Answer 6

In the mitochondria

Question 7

What is the word equation for aerobic respiration?

Answer 7

Glucose + oxygen -> carbon dioxide + water

Question 8

What is the symbol equation for respiration?

Answer 8

C6H12O6n+ 6O2m-> 6CO2 + 6H2O

Question 9

Aerobic respiration is an ___ process

Answer 9

Enzyme-controlled

Question 10

What happens during aerobic respiration?

Answer 10

During aerobic respiration glucose (a sugar) reacts with oxygen which transfers energy that your cells can use

Question 11

How is the structure of mitochondria adapted for aerobic respiration?

Answer 11

Mitochondria have a folded inner membrane providing a large surface area for the enzymes involved in aerobic respiration
