Cell Membrane 2.0

The cell membrane is composed of a ...........

• phospholipid bilayer

• single layer of phospholipids

• carbohydrate bilayer

• single layer of carbohydrates

The heads of the phospholipids in the cell membrane are considered to be?

• hydrophobic: water loving

• hydrophilic: water loving

• hydrophobic: water hating

• hydorphilic: water wating

The tails of the phospholipids in the cell membrane are considered to be?

• hydrophobic: water loving

• hydrophobic: water hating

• hydrophilic: water loving

• hydrophillic: water hating

The molecules that have the ability to move in and out of the cell membrane

• are smaller molecules

• require a lot of extra energy (ATP) to move in and out of the membrane

• are large molecules

• have to adapt to the inside environment of the cell

Select ALL that describe the cell membrane.

• Selectively Permeable

• Fluid Mosaic

• Nucleus

• Phospholipid Bilayer

Cell membrane structures that are embedded in the phospholipid bilayer that identify and communicate with extracellular surroundings.

• Cholesterol

• Carbohydrate Chains

• Proteins

Identify what part of the cell membrane that is represented by letter A.

• Phospholipid Bilayer

• Integral Protein

• Cholesterol

• Carbohydrate Chain

Analyze the cell membrane diagram. Identify the letter that is considered hydrophobic.

• F

• G

• H

• B

The 'membrane' pictured below would not be able to form because

• the 'heads' would repel each other

• the 'tails' would repel water on either side

• the cell membrane isn't a bilayer

• the membrane does not contain phospholipids

Describes the arrangement of the cell membrane as flexible, bendable, and made of many parts. 

• The Fluid Mosaic Model 
• The Major Mobility Model 
• The Crazy Cell Model
• The Maze Model
