Plasma membrane forms the outer most covering of an animal cell. Plant cells and bacterial cells have a cell wall outside the plasma membrane. Irrespective of the cell type, the plasma membrane is made up of a bilayer of phospholipids with a hydrophobic core. Several proteins are embedded in the lipid bilayer.
C because it has the highest rate of reaction at 37 Celsius
Answer:
c. binds to allolactose and becomes inactive, allowing lac gene expression to occur.
Explanation:
Interaction between allolactose and repressor leads to allosteric repulsion which makes repressor inactive leading to the lac gene expression. This is the reason why allolactose is known as the inducer of lac operon becasue it causes gene expression in lac operon.
In the absence of allolactose, the repressor binds the operator and does not allow RNA polymerase to do transcription.
