A transport protein moves potassium molecules from low concentration to high concentration. Which type of transport is being used?
Active Transport
100
The reason cells move substances in and out
To maintain homeostasis, release waste, and/or transmit molecules to other parts of the body
100
What does the term "selectively permeable" mean?
only letting some things through
100
In passive transport, molecules move from a _______ to ______ concentration
What is high to low?
100
What is the difference between active and passive transport?
Active requires energy (ATP) and goes against the concentration gradient
200
What type of cell transport would facilitated diffusion be?
Passive Transport
200
The type of solution where the concentration of solute is equal on both sides
What is an isotonic solution?
200
The type of transport is shown in the diagram
Facilitated Diffusion
200
When there is a higher SOLUTE concentration inside the cell than outside the cell, what type of solution is it?
hypotonic
200
The type of transport is shown in the picture
Active Transport
300
The heads of a phospholipid are ___________, meaning they are attracted to water.
hydrophilic
300
The organelle responsible for the production of energy (ATP) for your cell
Mitochondria
300
The main function of the cell membrane
To control what substances enter and exit the cell
300
__________ is the diffusion of water across a semipermeable membrane.
What is Osmosis?
300
Description of substances that CAN move across the cell membrane
small and non-polar
400
What cellular transport did this cell model demonstrate?
Osmosis (movement of water in/out of cell)?
400
Your teacher sprays an air freshener, and it slowly spread throughout the classroom This was an example of what type of transport?
Diffusion, passive transport
400
This type of solution has a greater concentration of solvent than solute; as a result if a cell is placed in it, the cells will usually swell
What is hypotonic solution?
400
During transport water will move in what direction?
What is INTO the cell?
400
What are the three types of passive transport?
Diffusion
Facilitated diffusion
Osmosis
500
The structure that makes facilitated diffusion different from other types of passive transport
channel protein
500
When a cell is in a state in which concentrations on the inside and outside are even, it has reached _______________
equilibrium
500
When we breathe in oxygen, it travels the blood stream and diffuses directly into our cells without the use of energy. What type of transport is this?
simple diffusion
500
A cell is placed in a hypotonic solution, what will happen after 6 hours
The cell will swell as the water moves into the cell.
500
What macromolecule is responsible for moving molecules into and out of the cell?
Proteins
