Cell Structure and Function

What type of transport does not require energy?

• Active transport
• Bulk transport
• Passive transport
• Facilitated transport

Why is the fluid nature of the membrane important?

• It prevents the entry of pathogens
• It provides rigidity to the cell
• It helps in functions like cell growth and division
• It stores energy for the cell

What is the ability of proteins to move laterally within the lipid bilayer called?

• Permeability
• Diffusion
• Osmosis
• Fluidity

What is the effect of temperature on membrane fluidity?

• Higher temperatures increase rigidity
• Temperature has no effect
• Only pH affects fluidity
• Higher temperatures decrease viscosity

What is the function of glycoproteins in the cell membrane?

• Energy production
• Waste removal
• DNA replication
• Cell recognition and signaling
