Why is a glucose more likely than a sucrose molecule to diffuse through an artificial membrane?

• Because sucrose is smaller

• Because glucose is smaller

• Because sucrose is bigger

• Because glucose is bigger

Which of the following statements describe passive transport?

• Molecules goes from low to high concentration using no energy

• Molecules goes from low to high concentration using energy

• Molecules goes from high to low concentration using no energy

• Molecules goes from high to low concentration using energy

Which statement best explains what selectively permeable means?

• The cell membrane prevents any harmful substance from entering the cell.

• The cell membrane lets certain substances enter the cell and keeps certain substances out of the cell.

• The cell membrane allows only large molecules to diffuse into the cell.

• The cell membrane has pores that let only water and glucose into the cell and carbon dioxide out.
