Transmembrane proteins span the width of cell membranes. Four types of transmembrane proteins are shown in the section of cell membrane. Although these proteins have different specific functions, they all -

• stop chemical reactions within the cell

• synthesize molecules that signal other cells

• help the cell interact with its external environment

• remove large waste particles from the cytosplasm of the cell

NGSS.HS-LS1-6

Match the biomolecule with it's functions:

• Proteins

• Provide quick energy source for cells (body’s first source of energy).

  Make up plant cell walls (cellulose or chitin).

  Form specialized sites on the cell surface that allow cells to recognize each other.

• Carbohydrates

• Help regulate hormones.

  Store energy in the form of body fat (insulation).

  Responsible for cell membrane tension, rigidity, and shape.

• Lipids

• Store and process genetic information.

  Direct cell processes (such as cell division and protein synthesis).

• Nucleic Acids

• Biochemical catalysts, enzymes and hormones.

  Protect against disease (antibodies).

  Provide structural support and aid muscle movement.

  Regulate the passage of substances across the cell membrane.

  Coordinate cell communication.
