Where can carbohydrates be found when part of a plasma membrane?

• On the outside of the membrane

• Embedded part of the way into the membrane

• On the inside of the membrane

• Embedded the whole way through the membrane

When do cells use active transport instead of passive transport?

• to move water molecules to the external environment in the same direction as the concentration gradient

• to transport nutrients from a high internal concentration out of the cell

• to diffuse oxygen across the cell membrane

• to transport nutrients from a low external concentration into a cell with a high concentration using ATP

What cellular structures is composed of a phospholipid bilayer with embedded proteins?

• cell membrane

• cell wall

• nucleus

A cell that is 45% water & 55% solute is placed in a beaker of with a water concentration of 75% and solute concentration of 25%. What will happen to the cell?

• water moves out of the cell and it shrinks

• water moves out of the cell and the cell swells

• water moves into the cell and the cell could burst

• water moves in and out of the cell at equal rates
