Cards (7)

briefly explain what homogenisation is?
Breaking up the cells
give examples of different ways that homogenisation can be done?
vibrating the cells
grinding the cells up in a blender
what does homogenisation do?
Breaks up the plasma membrane and releases the organelles into solution
why must the solution be kept ice-cold?
To reduce the activity of enzymes that break down organelles
What does isotonic mean?
The solution should have the same concentration of chemicals as the cells being broken down
why must the solution be isotonic?
To prevent damage to the organelles through mitosis
Explain the criteria for the solution?
kept ice-cold
isotonic
buffer added
