Homework Answers
- Active enzymes (holoenzyme) is made up of non- protein part (Coenzyme ) and protein part (apoenzyme).
- Coenzyme themselves cannot catalyze reaction but they help enzymes to so.
- So Coenzyme assist enzymes in accepting and donating molecules during reaction.
- So the correct answer is option 2.

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...
