Biology 1202B Lecture Notes - Lecture 6: Competitive Inhibition, Isoleucine, Endergonic Reaction
Document Summary
Enzymes are biological catalysts that increase the rate of reactions. Make reactions happen for us because without them most reactions would take more time than our life span. Most enzymes are proteins (protein enzymes: exception: rna that is not protein but are enzymes. Rna world hypothesis: rna came first, then dna and etc. Ribosomes has proteins and enzymes but it"s the enzyme part that does the catalysis. Enzymes are large proteins that fold into its 3d conformation. Only the active site or the catalytic size does the catalysis on the enzyme. Need helper proteins (cofactors) to work: co factors are molecules that help it faceplate its function, organic co-factors = vitamins, inorganic co-factors = minerals, vitamin or mineral deficiency has to do with the enzymes. Drugs are just competitive or non-competitive enzyme pathway inhibitors. Omp is a step in making prymadines nucleotides.
