Term
what are the six subfields in anatomy?
Definition
Surface anatomy, Regional anatomy, Systematic anatomy, Developmental anatomy, embryology, clinical anatomy.
Term
Homeostatic regulations
Definition
Usually use a:
Receptor that is sensitive to a particular stimulus.
Control center which recieves and processes the information supplied by the receptor and then sends out commands
Effector that responds to the commands of the control center and whose activity either opposes or enhances the stimulus
Term
Catabolism
Definition
the breakdown of complex molecules
Term
anabolism
Definition
the synthesis of new molecules
Term
endergonic reactions
Definition
absorb energy
Term
Nutrients
Definition
essential elemts and molecules normally obtained from the diet
Term
Metabolities
Definition
are molecules that can be sythesized or broken down by chemical reactions inside our bodies
Term
Hydrophilic
Definition
molecules that interact readily with water
Term
Hydrophobic
Definition
molecules that DO NOT readily interact with water
Term
Buffers
Definition
remove or replace hydrogen ions in a solution. Buffers and buffer systems in body fluids maintain the pH within normal limits
Term
Organic compounds
Definition
carbon, hydrogen are the main constituents which generally contain oxygen as well.
Term
Carbohydrates
Definition
Three major types:
Monosaccharieds(simple sugars)
Dissacharides & Polysaccharides (both formed from monosaccharides by dehydration synthesis
Term
5 most important classes of lipids
Definition
Fatty acids, eicosanoids, glycerides, steriods, phospholipids and glycolipids
Term
Steriods
Definition
Components of plasma membranes include sex hormones and hormones regulating metabolic activities and are important in lipid digestion
Term
7 types of protiens
Definition
structural, contractile, transport, buffering, enzymes, hormones and antibodies
Term
four levels of protein structure
Definition
Primary structure (amino acid sequence)
Secondary structure (amino acid interactions, such as hydrogen bonds)
Tertiary structure (complex folding, disulfide bonds, and interaction with water molecules)
Quaternary structure (formation of protein complexes from individual subunits)
Term
Substrates
Definition
interact to yield a product by binding to the enzymes active site
Term
Cofactors
Definition
are ions or molecules that must bind to the enzyme before substrate binding can occur
Term
Coenzymes
Definition
are organiz cofactors commonly derived from vitamins
Term
Nucleic acids
Definition
store and process info at the molecular level. The two kinds of nucleic acids are deoxyribonucleic acid (DNA) and ribonucleic acid (RNA)
Term
DNA Nitrogenous bases
Definition
Adenine, guanine, cytosine and thymine
Term
RNA nitrogenous bases
Definition
Adenine, guanine, cytosine and uracil
