Physiology |
Study of the physical functions of living organisms |
|
|
Four Primary types of Cells |
Epithelial Cells- barrier function, skin cells, endothelial cells Connective cells- connective and anchor, bone, blood cells Nerve cells- communication, neuron Muscle cells- generate force, skeletal muscle cell, cardiac muscle cell |
|
|
Flood of Fluids through Body Compartments |
Nutrients: plasma > interstitial fluid > extracellular fluid > intracellular fluid Wastes: intracellular fluid > extracellular fluid > interstitial fluid > plasma |

|
Herders on Hasselbalch Equation |
pH= pKa + log (A-)/(HA) |
|
|
Components of Proteins |
-amino acids arranged in one long chain -side chain gives the shape (R group) -R group can tell us the function -central alpha connection connects R group to carboxylgroup and amino group -linked amino acids for peptide bonds |
|
|
Structural Levels of Proteins |
1°- linear chain, order of amino acids 2°- alpha helix, and beta sheet connected by loop conformation 3°- fully folded, 3D functional characteristics 4°- multiple tertiary protein assembled together |
|
|
Factors determining protein shape |
-Hydrogen bonds to side chains -Ionic bonds to side chains -Van Der Waal's forces (hydrophobic regions) -covalent linking of side chains (disulfide bonds) -denaturing agents (acetic acid, ethanol, formaldehyde)- disrupt protein structure |
|
|
Specificity |
Selectivity of binding site |
|
|
Affinity |
Strength with which ligand binds to its binding site |
|
|
What determines Chemical Reaction rates? |
-reactant concentration -energy of activation -pH -temperature -presence of catalyst |
