Which subtrate produces NADH the fastest between Ethanol, Methanol, Isopropanol and Acetone?
What does this imply about how well each substrate binds to the enzyme ADH?
Methanol produces the NADH fastest between ethanol, methanol, isopropanol and acetone.
This imply about how well these substrates bind to the enzyme alcohol dehydrogenase is that methanol is simplest primary alcohol and does not have any steric interference effect. So it fit very well in the active site of enzyme and produces NADH without any steric interference/ steric hindrance, whereas isopropanol is secondary alcohol which exhibit steric interference at the active site of enzyme more than methanol whereas acetone is a ketone and for tis oxidation C-C bond is to be broken which is resisted in normal condition and it has also has more steric interference than methanol. Ethanol also has more steric hindrance effect than methanol on the active site of enzyme. So, methanol produces the NADH fastest between ethanol, methanol, isopropanol and acetone. .

Explain how the absorbances vary between substrates. The absorbance was very low for Methanol, it was higher for Isopropanol & excen higher for acetone, & all absorbances for those 3 substrates were less than that of ethanol Consider the enzyme activity with...
4) (7 marks) Liver alcohol dehydrogenases (ADH) is relatively nonspecific. Its normal substrate is ethanol, however, it will oxidize other primary alcohols, such as methanol, to their corresponding aldehydes. In the case of methanol this produces formaldehyde, which is quite toxic and can lead to blindness. Mistaking it for the cheap wine she usually prefers, my dog Lulu ingested about 36 mL of windshield washer fluid, which is an aqueous solution of 50% v/v methanol. I knew that methanol would...

Please can you be specific on what does this imply about the
interpretation of the given interval. As well as how much would 99%
differ from 95% CI.
A 95% confidence interval obtained from a sample of 100 outpatients for the true population mean normal mean systolic blood pressure is given by (114 mmHG, 120 mmHG) . Provide a correct interpretation of this interval. Can you think of other interpretations that would also be correct? This confidence interval came from...
