Triosephosphate isomerase (TIM) catalyzes the conversion of dihydroxyacetone phosphate to glyceraldehyde-3-phosphate. The enzyme’s catalytic groups are Glu 165 and His 95. In the first step of the reaction, these catalytic groups function as a general-base and a general-acid catalyst, respectively. Propose a mechanism for the reaction.
Like all chemical reactions, the glycolytic pathway can be expressed as a balanced equation showing reactants on the left side of the equation and products on the right. The equations below describe (a) aerobic glycolysis and (b) anaerobic glycolysis (lactic acid fermentation). However, they are not balanced (i.e., they lack the correct stoichiometry). Complete the equations using the correct stoichiometry, assuming that each reaction starts with one molecule of glucose. glucose + ADP + Pi + NAD+ --> pyruvate + ATP + NADH + H+ glucose + ADP + Pi --> lactate + ATP

Imidazoleglycerol‑phosphate dehydratase is an enzyme in the histine biosynthesis pathway. It catalyzes the E1 dehydration of D‑erthyro‑imidazole‑glycerol phosphate to imidazole acetol‑phosphate. This is a rare example of a biological E1 reaction, as most biological elimination reactions occur through E1cB instead. In this reaction, D‑erthyro‑imidazole‑glycerol phosphate is first protonated to form a good leaving group. Then, the leaving group is ejected to form the resonance‑stabilized carbocation shown. Draw curved arrows forming the most stable resonance structure to explain why this reaction goes through an E1 mechanism. Draw curved arrows to form the most stable resonance structure.
