Cell Transport

Front

Which biomolecule makes up MOST of the cell membrane?

Back

phospholipids

Front

Which biomolecule helps LARGE molecules cross the membrane?

Back

proteins

Front

The cell membrane can separate the inside of the cell from the outside because of its phospholipids, which are

Back

hydrophilic on one side and hydrophobic on the other

Front

How does the cell membrane help maintain homeostasis in each cell?

Back

The cell membrane controls the movement of substances in and out of the cell

Front

What is the correct description of the transport in the image?

Back

many molecules coming into the cell using a membrane vesicle (endocytosis)

Front

What is the correct description of the transport in the image?

Back

small molecules crossing the lipid bilayer (diffusion)

Front

How are facilitated diffusion and protein pumps similar?

Back

They both involve the movement of molecules through proteins

Front

Facilitated diffusion and protein pumps are different because

Back

Protein pumps require energy while facilitated diffusion does not

Front

Using the image, choose the correct form of transport and explanation of how you know:
Options:

Active transport, because the molecules are crossing the membrane using a protein

,

Passive transport because the molecules are crossing the membrane using a protein

,

Active transport because the molecules are moving from low to high concentration

,

Passive transport because the molecules are moving from high to low concentration

Back

Passive transport because the molecules are moving from high to low concentration

Front

What happens during osmosis?

Back

Movement of water molecules from an area of high water concentration to an area of low water concentration
