This worksheet and quiz will assess what you know about cell fractionation. Certain concepts you will need to understand include why cells need to be broken in detergent and realizing the...
What is cell fractionation? The process where cells are broken up and the different organelles they contain are separated out. What happens before cell fractionation. The tissue is placed in a cold, buffered solution of the same water potential of the tissue. Why is the tissue placed in a buffered solution? So that the PH does not fluctuate .
Study with Quizlet and memorise flashcards containing terms like define cell fractionation, describe and explain how cell fractionation and ultracentrifugation can be used to isolate mitochondria from a suspension of animal cells, suggest and explain precautions that could have been taken to prevent osmotic damage to mitochondria and others.
The process of separating cell organelles from each other is known as cell fractionation; This process involves breaking up a suitable sample of tissue and then centrifuging the mixture at different speeds; Cell fractionation can be split into three stages: Homogenisation; Filtration; Ultracentrifugation
Study with Quizlet and memorize flashcards containing terms like Cells contain a number of different organelles give examples, What does - cell fractionation allow?, What happens in the first stage of ccell fractionation? and more.
This document provides instructions for a lab experiment on cell fractionation. It involves separating cell components through two main methods: 1) differential centrifugation, which separates components by size, and 2) density gradient centrifugation, which separates by density.
