Question

20 To what main class of enzymes does the enzyme that catalyzes the following reaction belong? OH A) oxidoreductase B) transferase C) hydrolase CH3 CCOO CH3 CHCCO- D) lyase E) isomerase HO-C- Acetycholne CH CH CH Acetic Acid +N-CH CHro CH Electrostatic altracton CH 13CH HO Chcino CH2CH2OH "Estenc Ste Acetylcholinesterase 21 The above graphic shows the action of aceylcholinesterase (ACHe) in the synapse region between neurons. What kind of reaction does ACHe catalyze? oxidation-reduction B) hydrolysis acid-base esterification transfer of atoms isomerization

Explanation / Answer

Ans 20: the reaction Is an example of oxidoreductase catalysed reaction. Since the carbonyl group is being reduced to alcoholic group, so it is catalysed by oxidoreductases
