Which of the following sentences is nottrue about alcohol dehydrogenase a. The enzyme uses NADH as cofactor. b. The enzyme transfers the hydride, H- between the substrates. c. If yeast alcohol dehydrogenase is reacted with CH3CD2OH, the generated NADH will contain deuterium in the pro-R position. d. If deuterium NAD+ is reacted with CH3CH2OH, the generated aldehyde will contain deuterium. e. If a pro-R deuterium NADH is reacted with Glyceraldehyde-3-phosphate dehydrogenase, deuterium will be remained in NAD+

4) Alcohol dehydrogenase is involved in the metabolism of alcohol. A cytoplasmic version of the enzyme catalyses the conversion of alcohol to acetaldehyde and a mitochondrial version catalyses the conversion of acetaldehyde to acetate, see reactions below. Some people react to the consumption of alcohol with the appearance of a facial flush. In less than 100 words total i) name the biochemical basis for this physiological reaction and ii) explain in the language of this unit how the enzymatic properties...

Sample problem 4: A newly discovered enzyme, mystery dehydrogenase, catalyzes the following conversion of an alkene to a ketoalcohol using NAD+/NADH as a cofactor: оон CH3-C-CH-CH3 CH3-CH=CH-CH3 - a) Will the nicotinamide dinucleotide cofactor be reduced or oxidized in the direction indicated? Reduced b) How many moles of NADH will be reduced or oxidized per mole of substrate? Two moles of NADH reduced per mol of substrate How do they get the answer for part B?

Ethylene glycol is an ingredient in antifreeze. If antifreeze is swallowed, the enzyme alcohol dehydrogenase binds to the ethylene glycol and converts it to tacowalic and glycolic acid. One of the treatments for ethylene glycol poisoning is the administration of the enzyme's natural substrate, ethanol. Based on this information, what is the best way to describe how ethanol protects against ethylene glycol poisoning? View Available Hints) Ethanol competes with ethylene glycol to limit akalic and glycolic acid formation Ethanol serves...

Alcohol dehydrogenase is an enzyme composed of several polypeptide subunits. It is normally expressed at high...
Alcohol dehydrogenase is an enzyme composed of several polypeptide subunits. It is normally expressed at high levels in the liver and the lining of the stomach. It is essential to metabolize alcohol, as without it, drinkers would become drunk faster and stay drunk longer. A scientist is studying mutations in mice that affect the activity of the enzyme. She finds that a heterozygote having a normal allele and a mutation that deletes the gene has 50% of normal enzyme activity....
