Cell Transport & Enzymes Quiz

Difference in solute concentrations between two adjacent regions

• concentration gradient
• passive transport
• Phagocytosis

A membrane is _________________, meaning that it allows some molecules to pass through but not others.

• Facilitated Diffusion
• semi-permeable
• Phospholipid Bilayer

Diffusion of WATER from an area of higher concentration to an area of lower concentration.

• Osmosis
• Facilitated Diffusion
• Pinocytosis

This cell organelle helps organisms maintain homeostasis by controlling what substances may enter or leave cells.

• Nucleus
• Cell membrane
• Cell wall

A process in which a cell engulfs (takes in) extracellular material through an inward folding of its plasma membrane.

• Facilitated transport
• Diffusion
• Endocytosis
• Exocytosis

Regulation of an organism's internal environment to maintain conditions suitable for survival (i.e. being in balance).

• concentration gradient
• Endocytosis
• Homeostasis
• Osmosis

Movement of particles across a membrane from an area of higher concentration to an area of lower concentration.

• Active Transport
• Passive Transport

Movement of MOLECULES from an area of higher concentration to an area of lower concentration.

• diffusion
• osmosis
• endocytosis

This picture represents which type of cellular transport? *Look at the arrows*

• Exocytosis
• Osmosis
• Endocytosis
• Receptor-Mediated Endocytosis

Process of diffusion( passive transport) in which molecules pass across the membrane through cell membrane channels or cell membrane proteins.

• Osmosis
• Facilitated Diffusion
• Pinocytosis
