QUESTION 2 An enzyme, rennin or chymosin is responsible for breaking down the proteins in milk, which results in the formation of curds and whey. You cannot use certain fresh fruits such as pineapple, kiwi, and papaya when making Jello because they contain an enzyme, papain which degrade the proteins in

Penicillin binds to transpeptidase thereby preventing enzyme activity. A) If penicillin binds at the active site, is this a competitive or noncompetitive inhibitor? 2) It is irreversible, so the bond formed between the enzyme and antibiotic is likely or hydrogen bond)?

A process that occurs in the human body is shown in the diagram (arrow's direction points to the direction of this hydrolysis reaction). What would happen if a temperature change -caused the shape of the enzyme's active site to be altered? + Active Site Dipeptide (Substrate) )-( Enzyme Enzyme-substrate Amino complex acids Dipeptide Breakdown ) - G The dipeptide would hydrolyze slower or not at all O The amino acids would combine slower or not at all The dipeptide would hydrolyze (break down) faster There will be no effect on the rate of this hydrolysis reaction The amino acids would combine faster + } Enzyme
The enzyme d-amino acid oxidase has avery high turnover number because the d-amino acids are potentially toxic. The KM for the enzyme is in the range of 1 to2 mM for the aromatic amino acids and in the range of 15 to20 mM for such amino acids as serine, alanine, and the acidicamino acids. Which of these amino acids are the preferred substrates for the enzyme?
Why are certain drugs called enzyme inhibitors?
