Type of Transport
Requires energy. Is this Active, Passive, Neither, or Both?
Active Transport
Which statement concerning osmosis and active transport is correct?
A. Both endocytosis and active transport require cell energy.
B. Active transport requires cell energy while osmosis does not.
C. Neither facilitated diffusion nor osmosis requires cell energy.
B. Active transport requires cell energy while osmosis does not.
The substance that is being dissolved by a solvent.
Solute
The Gatekeeper; controls what enters and leaves the cell.
Cell Membrane
This organelle sorts and packages proteins.
Golgi Apparatus
Endocytosis is an example of _________ transport.
Active
A solution that causes a cell to shrink because of the high concentration of solute in the solution surrounding the cell.
Hypertonic
The movement of water through a selectively permeable membrane from an area of high concentration to low concentration.
The semi-fluid stuff that is found within any cell. Contains dissolved salts.
Cytoplasm
The diffusion of water.
Osmosis
Utilizes the semi-permeable membrane and transports proteins. Active, Passive, Neither, or Both?
Both, Active and Passive Transport
When the concentration of solute and solvent are equal on both sides of the membrane.
Isotonic
A non-energy requiring process that moves materials across a cell membrane with the concentration gradient.
Passive Transport
Plant and animal cells differ in a variety of ways. Plants have a special structure that helps them produce their own food. Within this specialized structure, the plant is working hard to convert the energy from the sun into its own sugars. What is the name of this plant structure?
Chloroplasts
The substance that dissolves the solute.
Solvent
Does not require energy. Active, Passive, Neither, or Both?
Passive
A solution that causes a cell to swell because of osmosis.
Hypotonic
The process when molecules tend to move from an area of high concentration to an area of low concentration.
Diffusion
This is a tiny fluid-filled cavity in the cytoplasm. It can be used for storage of biochemicals.
Vacuole
All of the following processes require the cell to use ATP energy, EXCEPT?
A. Endocytosis
B. Active Transport
C. Passive Transport
D. Sodium-Potassium Pump
C. Passive Transport
Process requiring energy for the movement of particles across a cell membrane against the concentration gradient.
Which one of these scenarios most likely uses facilitated transport to move molecules across the cell membrane?
A. Oxygen moves from high to low concentration across the phospholipid bilayer.
B. K+ moves from low to high concentration using a membrane protein.
C. Glucose moves with the concentration gradient from high to low concentration using a membrane protein.
C. Glucose moves with the concentration gradient from high to low concentration using a membrane protein.
Active transport occurs in cells, for example, when the Na-K pump is at work. Any process that involves active transport most often involves the:
A. Movement of molecules without any predictable pattern.
B. Movement of molecules from a lower concentration to a higher concentration.
C. Movement of molecules from a higher concentration to a lower concentration.
B. Movement of molecules from a lower concentration to a higher concentration.
Initial sequence of nitrogen bases that determine type of protein comes from this organelle.
Nucleus
Facilitated diffusion and ________________ are alike since neither requires energy.
A. Endocytosis
B. Phagocytosis
C. Active Transport
D. Simple Diffusion
D. Simple Diffusion
