Passive transport

The cell membrane is mostly made of what 2 biomolecules?

• Lipids and Nucleic acids

• Protein and Nucleic acids

• Carbohydrates and lipids

• Lipids and Proteins

Lipids in the cell membrane provide what function?

• Allow large molecules to pass through the cell

• They provide the framework

• Allows cells to communicate with other cells

• Work as a glue to glue the cell membrane togther

Proteins in the cell membrane serve what major function ?

• They provide the framework of the cell

• They serve as attachment site

• They help with transport of materials in and out of the cell

• They allow cells to communicate with other cells

The cell membrane assist the cell in maintaining homeostasis by..

• Coding for our traits

• providing long term energy

• Allowing molecules to move into and out of the cell as needed

• speeding up chemical reactions
