Modeling Cellular Transport of Specific Molecules
Each group will be creating dynamic models of cellular transport of specific molecules using your bodies.
For each situation your group models,
be able to act out how the specific molecule will be transported across the cell membrane based on it and the cell membrane's properties,
be able to identify the type of transport you used for each type of molecule,
be able to identify the important components of the cell membrane that are involved,
be able to explain the structural properties of those components that allow it to participate in the transport.
The following types of molecules will be modeled by the two groups.
Small, polar molecules such as water down a concentration gradient (high to low)
Small non-polar molecule such as oxygen down a concentration gradient (high to low)
Medium molecules such as glucose down a concentration gradient (high to low)
Ions such as Ca+2 down a concentration gradient (high to low)
Large molecules such as starch or cellulose leaving the cell
Ions such as Na+2 and K+ up a concentration gradient (low to high)
After each group completes the demonstration of the
model, we will
give feedback
about aspects that were shown well and any tips for improvement.
