7.5.2-Cellular Transport-PASSIVE TRANSPORT QUIZ

G6D:

​

​The Cell Membrane is SELECTIVELY PERMEABLE!

​This means that only certain substances can enter or leave the cell.

​

​Just like the gif to the right, only the smaller blue substances can enter and leave the cell, but the green ones cannot.

​Passive Transport:

• ​Does NOT require energy!

• Moves particles from an area of high concentration to an area of low concentratio

Multiple Choice

Which is true of passive transport? 

• It requies energy (ATP)

• It does not require energy.

  (ATP) 

Multiple Choice

Passive transport moves particles from an area of ___  concentratin to an area of ___ concentration.

• low, high

• high, low

• it's all equal.

​Passive Transport Examples:

​1. Simple Diffusion

​2. Facilitated Diffusion

​3. Osmosis

​Passive Transport: Simple Diffusion

​Simple diffusion allows smaller particles, like oxygen and carbon dioxide, to move through the phospholipid bilayer without assistance.

​Substances move with the concentration gradient. This means they move from high to low concentration.

​Passive Transport: Osmosis

​Osmosis is the diffusion of WATER across the phospholipid bilayer of the cell membrane.

​The smaller particles are water molecules.

​Passive Transport: Facilitated Diffusion

​Facilitated Diffusion allows carbohydrates, amino acids, nucleosides, and ions to pass through the cell membrane USING PROTEINS as a doorway.

Multiple Choice

What is the concentration gradient?

• When particles move from low to high concentration.

• When particles move from high to low contration.

Multiple Choice

Which type of passive transport requires the use of a protein? 

• simple diffusion

• facilitated diffusion

• osmosis

• none of these.

Multiple Choice

Which type of passive transport moves substances like oxygen and carbon dioxide through the phospholipid bilayer?

Multiple Choice

Which of the following best describes dynamic equilibrium?

Multiple Choice

What is the primary difference between diffusion and facilitated diffusion?

• Facilitated diffusion uses transport proteins to move substances across the cell membrane

• Facilitated diffusion is the movement of water across the cell membrane

• Facilitated diffusion is the movement of molecules from an area of low concentration to an area of high concentration

Multiple Choice

Which of the following best describes osmosis?

• The movement of molecules from an area of low to high concentration

• The water level on both sides will increase
• The water level on both sides will decrease

Multiple Choice
