Respiration

Question 1

What is the definition of respiration?

Answer 1

• Respiration is the chemical process by which living organisms release energy (in the form of ATP) from organic food molecules (such as glucose).

Question 2

What is the word and balanced symbol equation of aerobic respiration?

Answer 2

• Glucose + Oxygen—–>
• Carbon dioxide + Water + Energy

Question 3

What is the word equation for anaerobic respiration in animals?

Answer 3

• Glucose ——> Lactic Acid + (Energy)

Question 4

What does the lactic acid do to your muscles?

Answer 4

• Lactic acid alters the pH of cells and starts to denature proteins, especially muscle proteins.
• You experience a burning sensation and eventually cramp as lactic acid builds up.

Question 5

How is oxygen debt prevented?

Answer 5

• Lactic acid is removed from muscle cells and transported to the liver.
• Here it is re-combined with oxygen and broken down.
• The breakdown process won’t take place until there is sufficient oxygen in the system, usually once exercise has finished.
• Pulse rate and breathing rate remain high after exercise in order to supply this oxygen – we call this “repaying the oxygen debt”.

Question 6

what is the word and symbol equation for anaerobic respiration in yeast and plants?

Answer 6

• Glucose—-> Ethanol+Carbon dioxide+Energy

Question 7

What is anaerobic respiration in yeast and plants often aslo called?

Answer 7

• sometimes called alcoholic fermentation, is the basis of brewing and winemaking and has been discovered by most human cultures at one time or another.
