Respiration Flashcards
What is needed for aerobic respiration?
Glucose and oxygen
Where does respiration happen?
In every cell in your body in the mitochondria
What are the waste products of aerobic respiration?
Carbon dioxide and water
What is the process of aerobic respiration?
The process of releasing energy from the breakdown of glucose
What is respiration controlled by?
Enzymes
What does respiration release?
Energy
What is the energy released from respiration used for?
To build larger molecules from smaller ones, enable muscle contraction in animals, to maintain a constant body temperature in animals, to build sugars, nitrates and other nutrients into amino acids and then proteins in plants
What is the most efficient way to release energy from glucose?
Aerobic respiration
What do investigations involving aerobic respiration usually measure?
The amount of carbon dioxide produced
What is used to detect carbon dioxide?
Limewater
What happens to limewater if carbon dioxide is present?
It turns cloudy
What happens when peas respire?
They release energy which heats the surroundings
What kind of respiration is used if there is not enough oxygen present?
Anaerobic respiration
What happens if your muscles have been contracting for a long period of time?
They become fatigued because of too little oxygen
When is anaerobic respiration used?
When there is not enough oxygen present for aerobic respiration
