Respiration Flashcards
What is respiration?
Respiration releases energy from glucose so that life processes can carry on.
What are the two types of respiration?
Aerobic and Anaerobic.
Tell me about Aerobic respiration.
Aerobic respiration requires oxygen from the air for it to work.
Tell me about Anaerobic respiration.
During hard exercise, not enough oxygen can reach your muscle cells. So, aerobic respiration is replaced with anaerobic respiration. This does not need oxygen for it to happen.
What is the formula in words for Aerobic respiration?
Glucose + Oxygen + Carbon Dioxide + Water + Energy
What is the formula for Aerobic respiration?
C6 H12 O6 + O2 + CO2 + H2O + Energy
What is the formula in words for Anaerobic respiration?
Glucose + Lactic Acid + Carbon Dioxide + Energy
What is the formula for Anaerobic respiration?
C6 H12 O6 + C3 H6 O3 + CO2 + Energy
Tell me about Anaerobic respiration in plants.
Anaerobic respiration in plants produces Ethanol and Carbon Dioxide as opposed to Lactic Acid.
What is the formula for Anaerobic respiration in plants.
Glucose + Ethanol + Carbon Dioxide
Define the term Gas Exchange.
We need to get oxygen from the air into the blood, and we need to remove waste carbon dioxide from the blood into the air. Moving gases like this is called gas exchange.
Define Inhalation.
Inhalation is the drawing in of a substance into the lungs.
Define Exhalation.
It is the movement of air out of the bronchial tubes, through the airways, to the external environment during breathing.
Compare Inhaled and Exhaled air.
Inhaled air contains more oxygen used to create energy and less carbon dioxide. Exhaled air contains more carbon dioxide and less oxygen as it has been used in respiration.
Explain why Respiration rates increase during exercise.
Exercise increases the rate at which energy is needed from food. This increases the need for both food and oxygen in the body.
