Cell Transport
What types of cells perform cell transport?
All of them - Prokaryotes & Eukaryotes
Semipermeable
Active transport ____________ energy.
requires/needs/uses
Passive transport ________ energy
does not need/require/use
if you have a cell with a concentration of 5g/mL in a solvent with a concentration of 5g/mL, which way would the water move?
the water would not move
What, generally, occurs during cell transport?
Substances move in and out of the cell
The cell membrane is made up of a _____________ bilayer.
Phospholipid
What are the two large categories of active transport?
Bulk Transport & Protein Pump
During passive transport, molecules move from an area of ______ concentration to ______ concentration.
High to low
What would happen to a cell if it had a concentration of 10g/mL and it was placed in a solvent with a concentration of 5g/mL?
The cell would swell and burst
Cell transport occurs when a cell is trying to maintain ___________.
Homeostasis
A phospholipid is made of _________ heads and _______ tails.
Hydrophobic heads and Hydrophilic tails
Active transport moves molecules from an area of _______ concentration to ________ concentration
Low to high
the movement of water across the cell membrane is known as
Osmosis
What would happen to a cell if it had a concentration of 5g/mL and it was placed in a solvent with a concentration of 10g/mL?
The cell would shrivel
Name a synonym for homeostasis
stable, same, level, balanced
This type of macromolecule helps facilitate molecules to move through the cell membrane.
Protein
During bulk transport __________ moves molecules into a cell and ________ moves molecules outside of the cell.
endocytosis and exocytosis
The movement of solute across the cell membrane using carrier or channel proteins is known as _______
facilitated diffusion
The example of a protein pump that we discussed in class was the _________ which functions in our brains/nervous systems.
Na/K pump
Describe the word concentration using the words "water" and "salt"
The "concentration" of salt is the amount of salt dissolved in water
This type of macromolecule acts as a name tag for the cell and lets it communicate with others
Carbohydrate
During protein pump transport, molecules are moved from an area of low concentration to high concentration using what form of energy?
ATP
When there is a higher concentration of solute inside the cell than outside, we call the solution __________. When the opposite is true, we call the solution ________.
Hypotonic and Hypertonic
Briefly describe how endocytosis happens with our immune cells.
immune cells pull in bacteria and foreign objects and then commit cell death (apoptosis)
