i wrote somthing on my essay but the professor said it was weak. please use the guidlines and comment  to write the essay. 
Message from professor: 
I have ready your draft. You have a very good start on the Introduction and the Methods sections.
For the Introduction, my suggestions for improvement are:
1). The structure of AP is known, and a catalytic mechanism has been proposed. You should go to the literature to identify the specific catalytic residues (identity and position in the primary sequence) and discuss the catalytic mechanism as a step-by-step process. As you do this, you should be able to identify where acid-base catalysis, electrostatic catalysis, and/or other catalytic strategies are being employed by AP in its mechanism.
2). What is the total rate enhancement provided by the enzyme? This should be discussed in the context of the mechanism you describe from the literature.
3). Your discussion of kinetic theory is incomplete. Consider my Kinetics PowerPoint from the lecture class. It is more than 30 slides long and constitutes an entire chapter of the textbook. How can you capture the complete essence of kinetic theory in only one or two paragraphs? Consider outlining major topics from the lecture materials and then writing paragraphs for each major topic in the order in which I presented it in class.
Please leave the claculation to me
