Summary Introduction
Introduction:
The interaction between the enzyme and the substrate is very essential for the occurrence of a particular type of reactions. The substrates act as the compound or molecule on which the enzyme shows the action. The attachment of the active site and the enzyme leads to the formation of the enzyme-substrate complex which finally converted into the products.

What is a signal peptide?
A.
A sequence of amino acids in endomembrane system proteins that directs them to the endoplasmic reticulum
B.
The sequence of amino acids in every protein that determines its location in the cell

d. Tyrosine
One approach to combat drug resistance in bacteria is to combine drugs to treat bacterial infections. For example, ampicillin, a beta-lactam antibiotic, is combined with clavulanic acid, a beta-lactamase inhibitor. Describe how these two drugs would act together to be more effective to treat a bacterial infection.
