Respiration Flashcards
Name the chemical reaction that transfers energy from glucose
respiration
State the word equation for aerobic respiration
glucose + oxygen –> carbon dioxide + water
State where in a cell respiration occurs
mitochondria
Name the component of blood that carries oxygen around the body
haemoglobin in the red blood cells
Name thwe component of blood that transports carbon dioxide
plasma
State the word equation for anaerobic respiration
glucose –> lactic acid
Give two reasons why the body normally respires aerbocically
more energy per glucose molecule, lactic acid causes cramp
Give an example of when your body might respire anaerobically.
Strenuous exercise like sprinting
Explain the term oxygen debt.
The extra oxygen needed to break down lactic acid produced from anaerobic respiration.
Explain why your breathing rate increases during exercise
More energy required, so more respiration. More oxygen needed and more carbon dioxide needs to be removed.
Explain why your breathing rate remains high after exercise
Oxygen is required to break down the lactic acid produced from anaerobic respiration.
Give one similarity between aerobic and anaerobic respiration.
Both release energy, both have gluse as a reactant, both chemical reactions.
Give one difference between aerobic and anaerobic respiration.
Aerobic uses oxygen, produces carbon dioxide and water, anaerobic releases less energy, produces lactic acid.
Name the products of anaerobic respiration.
Lactic acid
Name the products of fermentation.
ethanol and carbon dioxide.
