The sodium-potassium pump is a form of active transport that moves sodium ions outside the cell and potassium ions inside the cell.
Why is energy needed for active transport?
Ions are moving Low to High (against the concentration gradient)
The reason cells move substances in and out
What is maintain homeostasis, release waste, and/or transmit molecules to other parts of the body?
What does the term "selectively permeable" mean?
only letting some things through
The molecule that active transport uses to move large molecules against the concentration gradient
What is ATP?
Inside of cell : 75% salt, 25%water
Outside of cell: 70% salt, 30% water
Which way does water move and what is the name of the solution ?
Into cell
hypotonic
What is the difference between active and passive transport?
Active requires energy (ATP) and goes against the concentration gradient
What type of cell transport is represented by a high to low concentration gradient?
Passive Transport
The image shows the process of __(1)__ across the cell membrane to maintain cellular __(2)__.
What are molecule transport and homeostasis?
The type of transport is shown in the diagram
What is Facilitated Diffusion?
The are of higher SOLUTE concentration where water will exit the cell through osmosis
What is OUTSIDE the cell?
The type of transport is shown in the picture
What is Active Transport?
What are the two types of bulk transport?
Exocytosis and Endocytosis
The heads of a phospholipid are ___________, meaning they are attracted to water.
hydrophilic
The organelle responsible for the production of energy (ATP) for your cell
What is the Mitochondria?
The main function of the cell membrane
What is to control what substances enter and exit the cell?
__________ is the diffusion of water across a semipermeable membrane.
What is Osmosis?
Description of substances that CAN move across the cell membrane
What are small and non-polar?
What are the three types of passive transport?
Diffusion
Facilitated diffusion
Osmosis
What cellular transport did this cell model demonstrate?
What is Osmosis (movement of water in/out of cell)?
The air freshener your teacher sprayed is an example of diffusion. This was an example of what type of transport?
What is passive transport?
The substance moved during OSMOSIS
What is WATER?
During transport water will move in what direction?
What is INTO the cell?
Water moves into a cell when the solution surrounding the cell is
What is Hypotonic?
What is a CHANNEL PROTEIN?
The gradual change in the concentration of a substance within a given volume
What is CONCENTRATION GRADIENT?
List three main parts of a cell membrane.
Phospholipids, Protein channels, Cholesterol, Glycoproteins/lipids
If the inside of a cell contains 55% solute and the outside is composed of 25% solute, what direction will water move and what will happen to the cell?
Water will move into the cell causing it to burst if it an animal cell or become turgid if it is a plant cell
Water will move OUT of a cell when the surrounding solution is______________
What is HYPERTONIC?
