Cell Membrane and Cellular transport test review

Which example best relates to Osmosis?

• A fish uses its gills to pump salt out of its body and into the ocean water.

• Cellular waste is excreted from cells within a moose to then be evacuated from its body

• A tree uses its root cells to pull in higher concentrated water from the soil

• A human cell uses a carrier protein to move glucose into the cell

The cell membrane is made of what?

• Two layers of phospholipids with proteins

• Cytoplasmic fluid

• DNA

• Ribosomes

This image shows molecules inside and outside of a cell.

The image represents what?

• Osmosis

• Diffusion

• Active transport

• Carrier Proteins

Based on this image, if no energy is involved, what is happening?

• Osmosis

• Diffusion

• Facilitated Diffusion

• Active transport

What is shown in this image?

• Active transport

• Facilitated Diffusion

• Osmosis

• Diffusion

When there is no energy involved and non-polar particles move into or out of the cell (some can use channel proteins), this is known as what?

• Active transport

• Passive transport

• Osmosis

• Cell regeneration

Secretion from a cell, cellular excretion, or cellular export or materials are all terms that can be used to describe...

• Endocytosis

• Pinocytosis

• Phagocytosis

• Exocytosis

Looking at the Hypertonic solution.. what is a true statement?

• The concentration of water is higher inside the cell, and the concentration of solute outside of the cell is higher.

• The water will leave the cell to try to reach equilibrium, causing the cell to shrivel

• Both options are True

Looking at Hypotonic solution, what is a true statement?

• There is a higher concentration of solute inside the cell than outside of the cell which causes water to rush in and potentially pop the cell.

• There is a higher concentration of water outside the cell and will rush in to try to reach equilibrium.

• Both options are True

Looking at the Glycoprotein, we see that it has a carbohydrate chain on it. What is the function of a Glycoprotein?

• Identify what type of cell it is.

• Allow movement of molecules in and out of the cell

• Hold the DNA

• Fix any breaks in the membrane
