WebMar 5, 2024 · 4.5: Enzyme Flexibility. As mentioned earlier, a difference between an enzyme and a chemical catalyst is that an enzyme is flexible. Its slight changes in shape (often arising from the binding of the substrate itself) help to position substrates for reaction after they bind. These changes in shape are explained, in part, by Koshland’s Induced ... WebStudy with Quizlet and memorize flashcards containing terms like Alpha motor neurons innervate ________.

WebMay 15, 2012 · As each successive oxygen binds to the molecule, the structural changes described above result in the molecule relaxing, enlarging the crevice on adjacent globin chains and increasing their oxygen affinity. When fully oxygenated with four oxygen molecules, the haemoglobin achieves its ‘R’ or ‘relaxed’ quaternary structure. Fig 2 WebDec 1, 2003 · Smooth muscle relaxation occurs either as a result of removal of the contractile stimulus or by the direct action of a substance that stimulates inhibition of the contractile mechanism. Regardless, the process of relaxation requires a decreased intracellular Ca 2+ concentration and increased MLC phosphatase activity.
