Cell Transport Intro

Multiple Choice

What is the function of the carbohydrates of the cell membrane?

• allows large molecules to pass through the cell membrane

• allows small, non-polar molecules to pass through the cell membrane

• identifies the cell and allow for cell-to-cell communication

• stabilizes the fluidity of the cell membrane

Drag and Drop

The cell membrane, also known as the ​

membrane, is found in ​

Placeholder

types of cells. It controls and ​

Placeholder

what is allowed in and out of the cell to help maintain ​

Placeholder

or a balanced environment. It also is known as the ​

Placeholder

because the different parts of the cell membrane can move around and are not fixed in one location.

Multiple Choice

What is the "big idea" of the fluid mosaic model of plasma membranes?

• the plasma membrane creates a specialized FLUID that looks like a MOSAIC.

• the plasma membrane is a MOSAIC.

• the fluid mosaic model is NOT related to the plasma membrane.

• a plasma membrane is a MOSAIC of components that move FREELY and FLUIDLY.
