Respiration Flashcards
Respiration releases energy to:
Build up larger molecules
Contract muscles
Maintain a steady body temperature
Respiration:
The process of breaking down glucose to release energy, which goes on in every living cell
Aerobic respiration needs:
Plenty of oxygen
Aerobic respiration is the most efficient way:
To release energy from glucose
Word equation of aerobic respiration:
Glucose + Oxygen - Carbon Dioxide + Water (+ Energy)
Diffusion:
The movement of particles from an area of higher concentration to an area of lower concentration
Anaerobic respiration:
Doesn’t use oxygen at all
When does anaerobic respiration happen:
When there’s not enough oxygen available.
Word equation for anaerobic respiration:
Glucose - Lactic Acid (+ Energy)
How much energy does anaerobic respiration release:
Anaerobic respiration does not release as much energy as aerobic respiration
Anaerobic respiration produces a build up of:
Lactic acid in the muscles, which gets painful and can give you cramp
Advantage of anaerobic respiration:
You can keep using your muscles for a while longer
When you stop exercising (anaerobic respiration):
You’ll have an oxygen debt
What is an oxygen debt:
This means you have to repay the oxygen which you didn’t manage to get to your muscles in time
What do you have to do when you have an oxygen debt:
Keep breathing hard for a while after you stop to get more oxygen into the blood
Your heart rate also stays high to get the oxygen to your muscles, where it’s used to convert the toxic lactic acid to harmless CO2 and water
