B9 - Respiration Flashcards
What is aerobic respiration?
Aerobic respiration is a chemical reaction that transfers energy to the cells with oxygen.
What kind of reaction is aerobic respiration?
Exothermic as its releasing energy
What is the word equation for aerobic respiration?
Glucose + Oxygen -> Carbon Dioxide + Water
Why do you measure your pulse with your fingers and not your thumb?
Because your thumb has a pulse of its own
When you exercise extremely hard you puff and pant some time after you stop. Explain why this is the case
When you exercise hard (like sprinting) your body isn’t able to supply oxygen to your muscles quickly so they respire anaerobically.
After this your body has to “repay” the oxygen it didn’t get around quick enough so you breathe heavier to get more oxygen into your blood.
What is anaerobic respiration?
Anaerobic respiration is a chemical reaction that transfers energy to the cells WITHOUT oxygen
What is the word equation for anaerobic respiration?
Glucose -> Lactic Acid + Carbon Dioxide + Water (and some energy)
What is lactic acid?
A waste product produced when you respire anaerobically.
What happens after you have lots of lactic acid built up?
You get muscle cramp
