Day 3 Egg Lab

Thursday November 15^th

Corn syrup is made up of sugar molecules which are LARGE polar organic molecules.  With this said what do you think happened to the corn syrup and the egg in terms of diffusion?

Since corn syrup is made up of sugar molecules, and we know that the membrane is not permeable to large polar molecules, we can infer that the corn syrup did NOT move into the egg.

Here is some background on what corn syrup is made up of and the chemical formula for it.

If Corn syrup was able to move into the egg, what would it need to move through and what type of passive transport would this be considered.  It would need transport proteins and this would be considered facilitated diffusion. (Below is a video of an amination showing facilitated diffusion)

We then went through day 3 of the egg lab.  We took the egg out of the corn syrup, made observations of the egg and the liquid left in the beaker and made some predictions on what would happen tomorrow when the egg has sat in water for 24 hours.

Once we removed the egg from the corn
syrup we observed that it seemed "deflated"

The liquid in the beaker is much thinner than
what we put in there yesterday

We also observed that there was MORE liquid
in the beaker than what we added yesterday

We'll see what happens tomorrow when the egg is placed in water!
