Respiration 1

Question 1

What are the differences between Aerobic & Anaerobic respiration?

Answer 1

Aerobic Respiration:

Requires oxygen
Occurs in mitochondria
Produces carbon dioxide and water
Yields a large amount of energy

Anaerobic Respiration:

Does not require oxygen
Occurs in the cytoplasm
Produces lactic acid (in animals) or ethanol and carbon dioxide (in plants and yeast)
Yields a small amount of energy (2 ATP per glucose molecule)

Question 2

Respiration is also referred to as…

Answer 2

…an oxidation reaction, because oxygen is used to break down food molecules

Question 3

ATP IS PRESENT IN ALL LIVING THINGS

Answer 3

ATP IS PRESENT IN ALL LIVING THINGS

Question 4

What is ATP?

Answer 4

A chemical that passes the energy from respiration to the other processes (e.g. muscle contraction, cell division and active transport) that need it.

Question 5

What is respiration and what does it produce?

Answer 5

Respiration occurs in all cells of the body. It uses oxygen to oxidise food, releasing energy.
The primary food oxidised is glucose.

Question 6

How is ATP produced during respiration?

Answer 6

Glucose contains stored chemical energy.
Respiration converts glucose into ATP by breaking it down.
Some energy is released as heat, but most is stored in ATP molecules, which are then used for various cellular functions.

Question 7

What does ATP provide?

Answer 7

Energy for cells
