Answer:
Activated
Explanation:
In the presence of lactose, and in the absence of glucose, lactose will bind to a protein called a "repressor," deactivating it. Through this, RNA polymerase has a free way to synthesize the mRNA that will give enzymes for lactose degradation.
Answer:
enzymes are biological catalysts which speeds of up chemical reactions which is occuring on an organism
Explanation:
when an enzyme is deposited to a metabolic reaction, the active site of the enzymes me will be attaching to the substrate particle. then the substrate particle will be broken down to product particles
eg : starch + amylase gives maltose
Protein is found in dna but dna isnt an element
