The sodium potassium pump is an example of
Passive Transport
Active Transport
Facilitated Diffusion
Endocytosis
Human red blood cells contain 0.9% sodium chloride as a component of their cytoplasm. What would happen if an IV solution containing 3.5% sodium chloride is introduced into a person?
The red blood cell would get bigger and burst.
The red blood cell would stay the same size.
The red blood cell would shrink.
The red blood cell would first loose water and then absorb water.
If the body can no longer make ATP, which type of transport would be impacted?
Facilitated Diffusion
Osmosis
Active Transport
Simple Diffusion
If you could no longer make ATP, which type of transport could still occur. Choose all that apply.
Diffusion
Pinocytosis
Exocytosis
Osmosis
Diffusion occurs when molecules
move through a permanent barrier
move against the concentration gradient
move from high to low concentration
move from low to high concentration
A balloon allows water but not sugar to pass through it. The balloon contains a 5% sugar solution. A beaker contains a 10% sugar solution. Which statement is true?
Water will enter the balloon and it will swell
Water will leave the balloon and it will shrink
Sugar will enter the balloon
Water will enter the balloon via active transport
Look at the picture. What is most likely to occur over a period of time?
Oxygen will leave the cell.
Oxygen will enter the cell.
Carbon dioxide will leave the cell.
Carbon dioxide will enter the cell.
A plant's root cell already has a higher concentration of nutrients inside the cell than outside of the cell. How can the cell still take in nutrients?
Diffusion
Passive Transport
Active Transport
Facilitated Diffusion
Which of these would be best used to model a cell membrane in order to demonstrate osmosis?
glass that has a flat and uniform surface
rubber balloon that can expand and stretch without breaking
tissue paper that will easily rip and dissolve in water
tubing with many pores that are too small to see
What is the function of carbohydrates in the cell membrane?
The make up the majority of the cell membrane.
They act as channels for substances to pass through.
They act as name tags for the cell which is important for cell recognition and interaction.
They are not found in the cell membrane.
What is the function of proteins in the cell membrane?
to package and sort molecules to be sent in vesicles
to allow substances to cross the plasma membrane via active transport
to provide a hydrophilic head so that water can enter the cell
important in cell communication
How does the cell help to maintain homeostasis?
The cell membrane helps control the contents of a cell by combining simple molecules into complex molecules.
The cell membrane controls the concentration of organic molecules in a cell's cytoplasm.
The cell membrane produces enzymes that allow a cell to quickly carry out needed chemical reactions.
The cell membrane protects all of the organelles within the cell from injury.
What macromolecule makes up the channels found in the cell membrane?
Lipids
Carbohydrates
Nucleic Acids
Proteins
Which part of the phospholipid is hydrophobic?
Phosphate Head
Fatty Acid Tail
Which part of the phospholipid is hydrophilic?
Phosphate Head
Fatty Acid Tail
What type of molecules can easily diffuse through the cell membrane?
Small Molecules
Large Molecules
Charged Molecules
Nonpolar Molecules
What type of molecules CANNOT easily diffuse through the cell membrane and would need a protein to help them?
Small Molecules
Large Molecules
Charged Molecules
Nonpolar Molecules
What type of lipid forms the cell membrane?
Bilipid
Steroid
Phospholipid
Glycerol
Would this dissolve in water?
Yes
No
This is likely an image of which macromolecule?
Carbohydrate
Protein
Nucleic Acid
Lipid
You bought some fresh flowers from the store but they started to look wilted. Once you placed them in a vase full of water, the leaves and stems began to swell again. What process is responsible for this swelling?
Photosynthesis
Osmosis
Diffusion
Active Transport
You got your wisdom teeth removed and the doctor told you to rinse your mouth with salt water. Why?
The salt water is a hypertonic solution, and the swollen cells in Devin's mouth will release water through osmosis.
The salt water is a hypotonic solution, and the swollen cells in Devin's mouth will take in water through osmosis.
The salt water is a hypotonic solution, and the swollen cells in Devin's mouth will release water through diffusion.
The salt water is a hypertonic solution, and the swollen cells in Devin's mouth will take in water through diffusion.
Which process would best demonstrate osmosis?
a procedure that uses a banana that has been left overnight in milk
a procedure that uses the skins of potato left overnight in oil
a procedure that uses a 2-liter bottle filled with oil and water that is left overnight
a procedure that uses grapes left overnight in a high concentration of salt water
