Cell Transport / Cells Review

Particle of movement from an area of lower concentration to an area of higher concentration.

• Active transport

• Passive transport

Which type of passive transport focuses on the movement of water through the membrane?

• Facilitated diffusion

• Osmosis

• Diffusion

Active transport across a cell membrane from low to high concentration, requires

• energy (ATP)

• no energy

• water

• oxygen

Which type of passive transport uses proteins to help molecules pass through the membrane?

• Diffusion
• Facilitated diffusion
• Osmosis
• All of the above

What is diffusion?

• when molecules move from a low concentration to a high concentration 
• when molecules move from a high concentration to a low concentration.
• no movement 
• molecules move everywhere

A general term for the various types of active transport that move particles into a cell by enclosing them in a vesicle made out of plasma membrane.

• Endocytosis

• Exocytosis

• Osmosis

• Diffusion

A form of bulk transport in which materials are transported from the inside to the outside of the cell in membrane-bound vesicles that fuse with the plasma membrane.

• Endocytosis

• Exocytosis

• Osmosis

• Diffusion

What type of transport is this?

• Endocytosis
• Exocytosis
• Diffusion
• Sodium-Potassium Pump

Which one is the definition of active transport?

• movement of particles through the cell membrane from a region of lower concentration to a region of higher concentration using energy in the form of ATP.

• passage of water molecules from a region of their higher concentration to a region of their lower concentration through a partially permeable membrane

• net movement of molecule from a region of higher concentration to region of lower concentration. Molecule down a concentration gradient

• net movement of molecule from a region of lower concentration to region of higher concentration. Molecule down a concentration gradient

Which diagram best shows the end result of diffusion?

• F
• G
• H
• J
