effect of glucose on cell membranes

Postby benny » Tue Oct 04, 2005 2:06 pm

what effect does glucose have on the permeability of cell membranes?

that's weird, because i'm doing a laboratory session on cell membranes and permeability and one of my pre lab questions is "what are the effects of glucose on cell membranes and pemeability?"

This is how glucose dhould move about in the cell

There are sugar parts in the membrane in the form of glycoproteins and glycolipids.

is the glucose not has any bond with the cell membrane?
we need this information to answer yours.

glucose

Postby benny » Thu Oct 06, 2005 5:04 pm

For our experiment we have to cut up little cubes of beetroot and immerse them in 11 solutions, one of which is a mix consisting of 10% glucose and 1% formaldehyde. I guess the rest is water. This is all at room temperature of course. We then have to use a spectrophotometer to measure the absorption of each beetroot sample after 15 minutes, 30 minutes and 45 minutes. At the end of all this one of the questions we have to answer is "How does glucose affect cell permeability and why?"
For that matter the next question is how does formaldehyde affect permeability and why?

I suggest you read the theory for the lab experiment that you're doing.

Do the experiment and find out :wink:

Hey, I am doing the same experiment, i suspect we may be in the same stream in biology, since it shows that your from adelaide.

anyway this website may prove useful to you

hope its useful for you :?

Glucose and cell permeability

Postby Sparkles » Sun Oct 09, 2005 5:49 am

I think the effect of glucose on permeability has something to with its cotransport with sodium that creates an electrochemical gradient.
