Document Summary
Enzymes and energy: circe effect is a measure of how many of molecules will have achieved the activation energy. Proteins can be denatured by physical factors such as temp and ph: environment can alter enzymes functional properties: denaturation, temperature, hydrogen ion concentration, solutes, hydrostatic pressure. What sets the upper temp limit for life: the prescence of liquid water or the stability of biological molecules: stability of biological molecules, at high temps biological moleculesl such as protein and dna, break down very rapidly. Enzyme homologs: comparable enzymes from different organisms. Biological reactions: cofactos/coenzymes: nad (oxidized, nadh ( Reduction=the addition of electrons or hydrogen to a molecule, adds energy. Oxidation=the removal of electrons or hydrogen from a molecule, reduces energy. Substrate and inhibitor compete for binding to the active site of the enzyme. Inhibitor binds at a site away from the substrate binding site.
