A H57K mutation in chymotrypsin would have as compared to the wild type. decreased KM decreased kcat increased KM O no difference (mutation has no effect) Which of the following is true about the pyruvate dehydrogenase complex (PDHC)? Decarboxylation occurs first. OPDHC catalyses a substrate level phosphorylation. The sulfur atoms in the lipoamide arm assist by carrying protons. OPDHC catalyses the most rate limiting reaction in cellular respiration. NADH is produced by E1. The PDHC contains 5 enzymes.
