what do enzymes do? how do they ease chemical rection?
Homework Answers
enzymes are biocatalyst which are proteins in nature and enhance biological reaction. enzymes catalyze biochemical reactions with out taking active part in main reaction. enzymes do this by lowering activation energy of reaction. enzyme have special site called active site where substrate bind .this activation site lock and hold substrate is a such way which enhance reactivity of reaction group or enzymes gives temporary charge to substrate to start reaction of it changes shape of substrate which is favorable for reaction or enzyme decrease particles motion in substrate. in this way enzymes ease chemical reaction

Question 18 4 pts What role do restriction enzymes play in bacteria? How do bacteria protect their own DNA from the action of restriction enzymes? Change the surface proteins of bacteria; since DNA is not protein, there is no need for protection Cut foreign DNA into pieces; bacteria have RNA genomes. Destroy invading viral DNA: bacterial DNA does not contain the restriction enzyme recognition sequences. Restrict the growth rate of bacteria; bacterial DNA is restriction enzyme resistant.
