NST Exam 2 Study Guide! I. Proteins Function of body protein: antibodies in the immune system‚ muscle contraction and movement‚ enzymes that facilitate biochemical reactions (catalysts)‚ hormones that regulate bodily activities‚ structural proteins that provide support‚ such as with keratin and collagen‚ found in connective tissues‚ storage proteins store amino acids‚ transport proteins carry molecules/nutrients from one place to another (i.e. hemoglobin). Also contributes to acid base balance

competitive binding drugs can cause a decrease in the amount of drug bound to protein and increase the biological active fraction of the drug. The aim of this study is to analyze the interactions of Lomefloxacin (LMF) and Colchicine (COL) with human serum albumin (HSA) and to evaluate the mechanism of simultaneous binding of LMF and COL to protein. Fluorescence analysis was used to estimate the effect of drugs on the protein fluorescence and to define the binding and quenching properties of drugsHSA complexes

to form new cells is the basis for all reproduction and for the growth and repair of multicellular organisms‚ including humans. Two Major Kinds of Cells Eukaryotic cells- Membrane enclosed organelles in which DNA is organized along with certain proteins into structures called chromosomes contained within a nucleus‚ the largest organelle of most eukaryotic cells. Around the nucleus is a cytoplasm in which are suspended the various organelles that perform most of the cells functions. Plants eukaryotic

chemical reactions that occur in perfect synchronization. Also‚ these reactions take place at an incredibly fast rate; however‚ without enzymes‚ these reactions could possibly take several years to complete. An enzyme is a macromolecule‚ generally a protein‚ that lowers the activation energy of a reaction without being changed by the reaction‚ and this causes the reaction to occur much faster than usual (Campbell et al.‚ 2014). The act of speeding of a chemical reaction is called catalysis‚ and molecules
