AP Biology Unit 2 Cell Membrane, Transport, and Osmosis Basics

Which type of cell transport requires energy and can move substances from areas of low concentration to areas of high concentration across a semipermeable membrane?

• Diffusion

• Facilitated Diffusion

• Osmosis

• Protein Carriers

• Vesicular transport

Which type of cell transport does not require energy and can move substances from areas of high concentration to areas of low concentration across a semipermeable membrane, using assistance like a protein channel?

• Diffusion

• Facilitated Diffusion

• Osmosis

• Protein Carriers

• Vesicular transport

Which type of cell transport does not require energy and can move substances from areas of high concentration to areas of low concentration directly across a semipermeable membrane, without the need for assistance like a protein channel?

• Diffusion

• Facilitated Diffusion

• Osmosis

• Protein Carriers

• Vesicular transport

Which type of cell transport carries substances across the cell membrane from high concentration to low concentration, typically, requiring no energy?

• Active Transport

• Passive Transport

Which type of cell transport carries substances across the cell membrane from Low concentration to High concentration, typically, requiring energy to do so?

• Active Transport

• Passive Transport

Which type of cell transport requires energy?

Which type of cell transport does not require energy?

During what process do water molecules move across a semi-permeable membrane using passive transport, either directly or through protein channels called aquaporins?

What is the name of the macromolecule that makes up the cell membrane?

How many layers compose the cell membrane?

• Two layers of phospholipids

• Two regions, one hydrophobic, one hydrophilic

• Four regions, two outer hydrophilic regions and two inner hydrophobic regions

• Four regions, two inner hydrophilic regions and two outer hydrophobic regions
