What is resolution?
The minimum distance 2 objects can be apart in order for them to be distinguished as 2 separate items.
1 of 5
Why is an isotonic solution cold?
To reduce enzyme activity that may break down the organelles
2 of 5
Why is an isotonic solution buffered?
To prevent pH from fluctuating, can alter the structure of the organelles and the functioning of the enzymes
3 of 5
Why is an isotonic solution of the same water potential as the tissues?
To prevent the bursting/shrinking of organelles due to osmotic gain/loss of water
4 of 5
Describe the method of cell fractionation
Tissues are placed in an isotonic solution. The organelles are released from the cells by a homogeniser. The homogenate is filtered to remove complete cells and debris. The filtered homogenate is span at a high speed. Heaviest
