Question

1. Complete the following sentences

Word bank: competitive, noncompetitive, allosteric site, oxaloacetate, active site, different from, similar to, succinate

• Oxaloacetate would be a reversible ______ inhibitor because the structure of oxaloacetate is ______ the structure of succinate, the substrate for the enzyme.
• As a _____ inhibitor, oxaloacetate would bind to the ______ of the enzyme.
• Increasing the concentration of _______, the substrate for the reaction, would reverse the effect of the _____ inhibitor.

2. Complete the following sentences

The ______ structure of a protein is the sequence of _____ in its chain. This level of protein structure, which determines the other three kinds of structure, is maintained by the covalent peptide bonds.

Word bank: secondary, tertiary, quaternary, primary, amino acids, nucleotides

Answer 1

ch ) Oxaloacetate would be a reversible competitive inhibitor because structure of oualoacetile is similar to the structure of succinate, the substrate for the enzyme. As a competitive inhibitor, onaloacetate would bind to the active site of the enzyme. Increasing the concentration of succinate, the substrate for the reaction mould reverse the effect of the competitive inhibitor. 2. The primary structure of pustein is the sequence of amino acids in its chain. This level of protein structure, which determines the other three kinds of structure, is maintained by the covalent bepridě bonds.
