On the outside of the membrane.

Front

What type of proteins are embedded within the cell membrane?

Back

Integral proteins.

Front

Where do peripheral proteins sit in relation to the cell membrane?

Back

Atop/outside of the cell membrane.

Front

What is the function of the cell membrane?

Back

To protect the cell and regulate what enters and exits.

Front

What is the fluid mosaic model?

Back

A model that describes the structure of the cell membrane as a mosaic of various components that move fluidly.

Front

What role do carbohydrates play in the cell membrane?

Back

They are involved in cell recognition and signaling.

Front

What is the significance of the selective permeability of the cell membrane?

Back

It allows the cell to maintain homeostasis by controlling the movement of substances.
