| 4 Types of Chemical Bonds | Ionic, Covalent, Hydrogen and Peptide Bonds |
| What is Ionic Bond | dissolves in water, 2 types of charged particles |
| What is Covalent Bond | Should not dissolve in water, is a sharing of electrons. Carbons are always Covalently Bonded. |
| What is Hydrogen Bond | gives stability to large Compounds such as DNA/RNA proteins |
| Difference Between Potential NRG and Kinetic NRG | Potential nrg is stored or inactive nrg, Kinetic energy is NRG of motion |
| Difference between Electrical and Chemical Energy | Chem NRG is is released when bonds are broken and absorbed, electrical results from flow of charged particles |

| what is CH4 | Methane Gas |
| What is Organic Compound | Contain Carbon, always covalently bonded, Glucose, AA, FA |
| What is Inorganic Compound | All other compound, ionic bonding, H20, Salts, NaCl |
| Property of Water | Solvent dissolves solute |
| What is Suspension | it is when two substances do not mix together |
| Anabolism | dehydration synthesis, takewater to open spot for bond |
| Catablolism | hydrolysis put water back into to break bond |
| Define Acid | H+ Anions |
| Define Base | OH- Cation |
| Define Salts | nether positively/neg charged |
| pH scale | 0-14 |
| Carbohydrate | Sugar, startches, glycogen and cellulose |
| 3 types of Simple Sugars | Glucose, Galactose, Fructose |
| Types of Disaccharides | sucrose, maltose, lactose |
| Polysaccarides | starch glycogen |
| Nucleic Acids | DNA/RNA |
| 3 sub of Lipids | Triglycerides, Phospholipids, Steroids |
| Triglycerides are made of | 3FA and Glycerol |
| Bonding of Triglycerides | Saturated, Mono, poly |
| Phospholipids are | make up plasma membrane, polar heads, tail. |
| Steriods | are all cholesterol based |
| What defines proteins | Shape determines function |
| Amino Acid | Have Peptide bonds COOH |
| What is tRNA | Transfer RNA, translates the message AA |
| What ismRNA | Reads DNA Message |
| rRNA | finds a place for protein |
| Parts of Cell | Plasma Membrane and Cytoplasm |
| What is in Cytoplasm | Cytosol and Organelles |
| Phospholipid Bilayer | 50%Lipid 50% Protein |
| Integral Arrangment of Membrane Protein | extends into or across bilayer clothespin |
| Peripherial Arrangment of protein | loosely attached to inner and outer surface |
| What is Tonicity | measure of solutions ability to change the volume of cells by altering there H20 |
| what is isotonic | normal shape |
| what is hypertonic | there is more concentration inside than outside |
| what is hypotonic | when concentration is higher outside than inside |
| Simple Diffusion | is when the FA is passed through polar head and tail no NRG is expended |
| Facilitated Diffusion | Glucose passes through pores, pores change shape to accept no NRG is expended |
| Active Transport | NaK pump, NRG is used to move 3Na out 2 K |
| What is endocytosis | bringing substance into cell |
| 2 types of endocytosis | Phagosytosis and Pinosytocsis |
| Centriole | development / growth of mitotic spindle |
| Ribosomes | location protein synthesis |
| Er | Movement of molecules to Golgi Body |
| Golgi Body | Packs proteins for movement |
| Cell Junction | occur in Epithelial Cells and some muscles |
| Types of Cell Junctions | Tight Junction, Desmosomes, Gap Junction |
| What is Gap Junction | open channels for communication pruposes |
| What is Desmosomes | fibers interlock between cells to allow contract |
| Avascular | has no blood supply |
| where do you find Simple | lung kidneys |
| Connective tissue | most abundant and widely distributed tissue in the body |
| What does "blast" mean | to make |
| what is fibroblast | CT Proper |
| Chondroblast | cartiliage |
| osteoblast | bone |
| hemocytoblast | blood cells |
| macrophages | WBC that do Phagocytosis |
| Mast Cells | secrete histamine which enhance inflammation |
| Collagen | needed to make Connective tissue and also the most abundant proein in the body |
| Areolar CT | located hypodermis |
| adipose | hypodermis used to store Triglcerides |
| dense irregular | found in dermis and pericardium |
| Cartilage, bone and blood are | Connective Tissue |
| Epidermis is... | outer thinner layer |
| dermis | below epidermis made up of Dense irregular Connective Tissue |
