Diffusion and Cell Membrane Candy Quiz

1.) Diffusion is defined as…A. Defined as the movement of particles from areas of low

solute concentration to areas of high solute concentration (up the concentration gradient)

B. The movement of particles from areas of high solute concentration to areas of low solute concentration (down the concentration gradient)

C. No movement between particles of solutes

2.)

The picture depicts which type of cellular transport?A. OsmosisB. DiffusionC. Active TransportD. Endocytosis

3.)Which of the following is NOT a type of passive transport?A. DiffusionB. EndocytosisC. Facilitated diffusionD. Osmosis

4.) Which of the following is NOT a type of Active transport?A.) EndocytosisB.) ExocytosisC.) DiffusionD.) Sodium Potassium Protein Pump

5.) Which of the following does NOT effect the rate diffusion occurs in the cell?A.) Size of moleculesB.) Time allowedC.) Concentration of moleculesD.) Temperature

6.) In yesterday’s lab you placed starch into a baggie and iodine into a beaker. The _________ was permeable to the cell membrane (baggie) and the ________was not because…..A.) Starch; iodine; starch molecules were able to pass through the baggie via diffusion (low solute concentration high solute concentration)

B.) Starch; iodine; starch molecules were able to pass through the baggie via diffusion (high solute concentration low solute concentration)

C.) Iodine; starch; iodine molecules were able to pass through the baggie via diffusion (high solute concentration low solute concentration)

D.) Iodine; starch; iodine molecules were able to pass through the baggie via diffusion (low solute concentration high solute concentration)

7.) What is the difference between active transport and passive cellular transport?A. Active transport requires energy to transport molecules across the

cell membrane and passive transport does notB. Passive transport requires energy to transport molecules across the

cell membrane and active transport does notC. Active transport and passive transport require the same amount of

energy from the cellD. No energy is needed to transport molecules across the cell

membrane

8.) Who am I?• I am a protein molecule that is permanently attached or

firmly anchored in the plasma membrane. I also serve as transport proteins, chemical receptors, and regulators for cell to cell recognition.

9.) Who am I?• I attach to membrane proteins and serve as

identification tags, allowing cells to distinguish one type of cell from another. Cell recognition and cell signaling.

10.) Who am I?

• I am a protein that is not embedded and is loosely attached to the surface of the cell membrane.

11.) Who am I?• I am found in animal cell membrane and effect fluidity

(how easily the structure can move) depending on temperature. I also strengthen the cell membrane.

12.) Who am I?

• I am composed of three basic parts: a charged phosphate group and glycerol “head”, and two fatty acid chains “tail”.

8.) Integral proteins• I am a protein molecule that is permanently attached or

firmly anchored in the plasma membrane. I also serve as transport proteins, chemical receptors, and regulators for cell to cell recognition.

9.) Carbohydrate chains• I attach to membrane proteins and serve as

identification tags, allowing cells to distinguish one type of cell from another. Cell recognition and cell signaling.

10.) Peripheral Protein

• I am a protein that is not embedded and is loosely attached to the surface of the cell membrane.

11.) Cholesterol• I am found in animal cell membrane and effect fluidity

(how easily the structure can move) depending on temperature. I also strengthen the cell membrane.

12.) Phospholipid

• I am composed of three basic parts: a charged phosphate group and glycerol “head”, and two fatty acid chains “tail”.
