Membrane and Cell transport

The structure of the cell membrane is a:

• phospholid monolayer

• phospholipid bilayer

• protein bilayer

• carbohydrate monolayer

Choose one that is a function of proteins in the cell membrane:

• Osmosis

• Diffusion

• Energy production

• Protection

Osmosis and diffusion are types of:

• Cell transport

• Organelles

• Cell walls

• Nucleic acids

Osmosis is:

• Movement of water from higher concentration to lower concentration

• Movement of water from lower concentration to higher concentration

• Movement of solute from lower concentration to higher concentration

• Movement of solute from higher concentration to lower concentration

Diffusion is:

• Movement of water from higher concentration to lower concentration

• Movement of water from lower concentration to higher concentration

• Movement of solute from lower concentration to higher concentration

• Movement of solute from higher concentration to lower concentration

Carbohydrates in the cell membrane have the function of:

• Tell our immune system (the defense system) the cell belongs to our body

• Protect the cell from being invaded

• Protect the cell from mechanical damage

• Produce energy so the cell membrane can perform its functions

The function of cholesterol in the cell membrane is:

• Protect it

• Make energy

• Command the cell's activities

• Stabilize it

Hydrophobic means:

• Loves water

• Hates water

• Neutral to water

• Loves proteins

Hydrophilic means:

• Loves water

• Hates water

• Neutral to water

• Loves proteins

The phosphate head of phospholipids is:

• Hydrophobic

• Hydrophilic
