Biology help please.
1) Draw the 4 step process of an enzyme reacting with a substrate. LABEL the enzyme, the substrate, and the active site.
2) What is it meant by the phrase lock and key fit? Explain. What is induced fit? Explain.
3) Are enzymes generic or specific (i.e. can an enzyme catalyze any reaction, or only a specific reaction)? Explain why?
Thanks

Part A - Overview of enzyme structure and enzymatic reactions Enzymes are large globular proteins. Much of their three dimensional shape is the result of interactions between the R (variable) groups of their amino acids. The active site is the portion of the enzyme that will interact with the substrate the molecule that the enzyme acts upon. The nature and arrangement of amino acids in the active site make each enzyme specific to a substrate and to the reaction it...
