B. Gene expression is in them is similar to us but facilitates the use of bacteria in recombiant biotechnology and gene therapy.
We human have eukaryotic cells which have a devoloped nucleas whereas small bacteria have prokaryotic cells with no definite nucleus using more biotechnology. Other all are not true.
For example, pH can have an effect of the state of ionization of acidic or basic amino acids. Acidic amino acids have carboxyl functional groups in their side chains. Basic amino acids have amine functional groups in their side chains. If the state of ionization of amino acids in a protein is altered then the ionic bonds that help to determine the 3-D shape of the protein can be altered. This can lead to altered protein recognition or an enzyme might become inactive.
Changes in pH may not only affect the shape of an enzyme but it may also change the shape or charge properties of the substrate so that either the substrate connot bind to the active site or it cannot undergo catalysis.
In geneal enzyme have a pH optimum. However the optimum is not the same for each enzyme.
At room temperature the fat would be a solid.
