Respiration Flashcards
What is aerobic respiration and what is anaerobic respiration?
Aerobic - respiration (turning glucose into energy), using OXYGEN
Anaerobic - respiration WITHOUT oxygen
What is respiration?
Respiration means turning glucose into energy. It happens in every cell of every living organism.
Whereabouts in a plant or animal cell does AEROBIC respiration take place?
Mitochondria
What do we use the energy for that is made by respiration?
Everything the body does to keep you alive. For example - keeping warm, digesting food, growing, moving joints.
What is the EQUATION for aerobic respiration?
Glucose+oxygen = carbon dioxide+water+ENERGY
When does ANAEROBIC respiration usually take place?
When cells can’t get enough oxygen. This is because if there was enough oxygen, aerobic respiration would take place, not anaerobic.
How does ANAEROBIC respiration differ between humans and. Microorganisms (like yeast)?
Humans = Glucose turns into lactic acid+energy (this happens during exercise and it is the lactic acid that makes muscles ache).
Yeast = Glucose turns into carbon dioxide+alcohol+energy (also known as ‘fermentation’)
What is glucose a type of?
Sugar
When might humans respire ANAEROBICALLY instead of aerobically?
When they exercise eg running or swimming fast.
This is because when you exercise, your body can’t get enough oxygen to your muscle cells for AEROBIC respiration to happen.
What can fermentation be used to make?
Beer or wine.
This is because fermentation in Microorganisms (like yeast) produces alcohol.
What is the balanced chemical equation for respiration?
C6H12O6➕6O2🔜6CO2➕6H2O
C🔀6.
H🔀12.
O🔀18
How does oxygen get in the respiring cells?
When you breathe in the oxygen goes in the lungs into the alveoli and diffuses into the blood stream. The red blood cells carry haemogoblin it gets carried around in blood vessels called the capillary and when it gets to a cells needing oxygen it diffuses into the cell.
How do you measure lung volume
You get a little tube and and a special bag with measurements on it. Then wrap the bag around the tube and breath out to see what your lung capacity is.
What factors might affect breathing?
Hight weight running swimming exercise playing an instrument smoking asthma not doing any exercise if your ill
What are 5 functions of respiration?
To allow muscles to contract
To supply oxygen and remove carbon dioxide
To make larger molecules from smaller ones
To make energy, in all cells, all the time, in all living cells
Keeping warm
Building proteins
