Why is cellular transport important? |
|
Definition
*Cells need substances from blood *Cells need to dump wastes into blood Molecules made in one type of cell are used in other cells around the body |
|

Term
What cell transportation do kidneys do? |
|
Definition
Kidney cells take in wastes from the bood and form urine. |

|
Definition
*Remove toxins from blood *Take in sugar and convert to glycogen Make hormones that are released into blood *Make blood proteins and release into blood |
|

Term
|
Definition

|
Term
|
Definition
Cl (chloride) doesn't move correctly through cell membrane |
|
|
Term
Familial Hypercholesterolemia |
|
Definition
Cholesterol doesn't move and builds up in cholesterol bumps |

|
|
Term
What are some characteristics of a cell membrane? |
|
Definition
Selectively permeable, allows CERTAIN substances in and out the cell membrane. |
|
|
Term
Cell membranes are made up of phospholipids...what are phospholipids made up of? |
|
Definition
*phosphate group/hydrophilic(water loving) *2 fatty acieds/hydroPHOBIC(water fearing) |
|
|
Term
How are phospholipids arranged in the cell membrane? |
|
Definition
Arranged in a lipid Bilayer |
|
|
Term
What do Transport or transmembrane proteins do? |
|
Definition
Act as carriers or channels to transfer chemicals through lipids |
|
|
Term
What do Integral/Enzyme proteins do? |
|
Definition
Regulate biochemical reactions in the cell |
|
|
Term
What do receptor proteins do? |
|
Definition
recognize and bind to substances outside of cell like signal molecules...used for communication (hormones) Molecular "triggers" |
|
|
Term
What are Glycoproteins for? (carbohydrate end) |
|
Definition
Cell Recognition:What type of cell is it? Heart/Liver...etc. "Marker" to identify the cell. |
|
|
Term
What does cholesterol do? (steroid/lipid) |
|
Definition
Gives cell fluidity...(especially for cold weather, so membrane doesn't freeze) |
|
|
Term
|
Definition
Molecules flow with concentration gradient. Go from high concentration to low concentration. NO energy or ATP required. |
|
|
Term
Diffusion (a type of passive transport) |
|
Definition
Molecules moving from HIGH concentration to LOW concentration until equilibrium is reached. |
|
|
Term
Osmosis (special type of diffusion, passive transport) |
|
Definition
Movement of WATER from high water concentration to a low water concentration through a SELECTIVELY permeable membrane. |
|
|
Term
How many types of osmotic environments are there? |
|
Definition
3, three, tres
Hypotonic, isotonic, hypertonic |
|
|
Term
Hypotonic environment (one of the 3 osmotic environments) |
|
Definition
Little solute/LOTS of water |
|
|
Term
Hypertonic environment (one of the 3 osmotic environments) |
|
Definition
LOTS of solute/ little water |
|
|
Term
Isotonic Environment (one of the 3 osmotic environments) |
|
Definition
EQUAL amounts of solute and water |
|
|
Term
|
Definition
*Passive transport, with concentration gradient, high to low, uses a protein carrier, carries sugar and amino acids |
|
|
Term
|
Definition
USES energy/ATP, goes AGAINST concentration gradient, low to high, uses a protein carrier, carries Na+/K+ ions |
|
|
Term
Large molecule transportation |
|
Definition
Endocytosis (vesicle/lysosome, phagocytosis,pinocytosis) |
|
|
Term
Movement of food into the cell? |
