WebJul 4, 2024 · This enzyme catalyses the conversion of succinate ions to fumarate ions. The modern names are: malonate: propanedioate succinate: butanedioate fumarate: trans-butenedioate The conversion that succinic dehydrogenase carries out is: The reaction is inhibited by malonate ions which have a very similar shape to succinate ions. WebEnzyme inhibition can be categorized in three types: competitive, noncompetitive, and uncompetitive. Competitive inhibition happens when a compound similar to the substrate is present and competes with the substrate for the active sites of the enzyme obstructing the access of substrate to the active site, thus slowing down the reaction.37,38 hikousen meaning
