Cell Membrane Structure

Phospholipids create bi-layers because of their __________________ properties.

• Amphibious

• Amphipathic

• Polar

• Hydrophobic

The part of a phospholipid that is hydrophobic (non-polar) would be:

• The Glycerol

• The Phosphate

• The Hydrocarbon Tails

• The Whole Molecule

The protein labeled H would be considered:

• Peripheral

• Integral

• Transmembrane

• All are Correct

What function does the protein labeled J most likely have?

• Recognition

• Channel

• Receptor

• Adhesion

B is referring to what type of membrane protein?

• Enzymatic

• Receptor

• Pump

• Recognition

Letter i is referring to what molecule?

• Phosphate

• Hydrocarbon

• Cholesterol

• Glycerol

What is most likely the function of protein h?

• Adhesion

• Recognition

• Channel

• Enzymatic

Cholesterol is important in maintaining what in animal cells?

• Membrane Fluidity

• Membrane Structure

• Membrane Shape

• All of these are Correct

Gorter and Grendel's work on cell membranes was essential, because they discovered it was:

• Made up of a bilayer

• Made up of phospholipids

• Made up of a mixture of lipid and protein

• Both hydrophobic and hydrophilic

This model of the cell membrane was used for nearly 30 years. Which pair came up with it?

• Gorter and Grendel

• Davson and Danielli

• Singer and Nicolson

• Hall and Oates
