1
Q

What is respiration?

A

Glucose +oxygen –> carbon dioxide + water (+energy)

  • Exothermic reaction (gives out heat)
2
Q

Where does respiration take place?

A

-takes place in mitochondria but other parts of cells play a virtual role (cell membrane,nucleus etc)

3
Q

Why is respiration important?

A
  • it maintains body temperature
  • builds up/breaks down molecules
  • plant minerals
  • muscle contractions
4
Q

what is anaerobic respiration?

A

Anaerobic respiration is a chemical reaction that releases energy from glucose without using oxygen.

5
Q

when does anaerobic respiration happen?

A

It happens when oxygen cannot be delivered to the muscle fast enough (eg hard exercise)

6
Q

what is the equation for anaerobic respiration?

A

Glucose > lactic acid

7
Q

how is anaerobic respiration in yeast different to animals?

A

Almost all animals and humans are obligate aerobes that require oxygen for respiration, whereas anaerobic yeast is an example of facilitative anaerobe bacteria.
