1
Active transport
Able to move molecules against concentration gradient
2
No net movement
When solutions on either side of membrane are same concentration of water or solute
3
Turgor pressure in plants
Important in plants cells because as cells start to lose turgor pressure it wilts
4
Solute
The substance that is being dissolved in a solution
5
Carrier protein
Uses ATP to change shape to move molecules across cell membrane
6
Osmosis
Special type of diffusion where water is the moving substance
7
Hydrophobic
“Water fearing” - molecules that don’t mix well with charges or polar molecules
8
Isotonic
Refers to solution with same concentration when compared to another solution
9
Peripheral protein
Only passes part way through lipid bilayer of cell membrane
10
Active
Type of protein transport that requires ATP as an energy source
11
Gycolipid
A carbohydrate chain attached to lipid molecule in cell membrane
12
Hydrophilic
“Water loving” - molecules which mix well with charged or polar molecules
13
Concentration gradient
Rate of diffusion can be increased by increasing concentration gradient
14
Osmotic pressure
Occurs when there is a concentration gradient across a membrane and only water is able to pass through the membrane
15
Cell recognition protein
Has glycoproteins attached which are unique to each organisms and aid in immune system recognition
16
ATP
This molecule is the energy currency of the cell
17
Diffusion
Movement of molecules along a concentration gradient
18
Glycoprotein
A carbohydrate chain attached to a protein in the cell membrane
19
Endocytosis
Movement of a vacuole into the cell
20
Integral protein
Passes all the way through lipid bilayer of cell membrane
21
Hypertonic
Refers to solution that is more concentrated when compared to another solution
22
Passive
When movement of molecules don’t require additional energy input
23
Turgor pressure
If a plant cell is placed in a hypotonic solution, turgor pressure will develope
