Create a Venn-Diagram to compare & contrast CATABOLISM vs ANABOLISM such as its process/mechanism, relation with ATP, reaction type, etc. Moreover, provide at least two (2) specific metabolic pathways as examples for each. You can use coloring pens, crayons, and the like to make your presentation look appealing. Digital drawings are also acceptable.

Which statements are false? Initial velocities of enzyme reactions are best obtained in the absence of product because it simplifies analysis. Initial velocities refer to the velocity of the reaction right after it is initiated. The velocity of the reaction as a function of measuring time are curved just like an isothermal binding curve because of substrate binding to the enzyme. Initial velocities correspond to the pre-steady state condition for free enzyme. Initial velocities can sometimes be measured by spectroscopy such as UV/Vis spectroscopy when monitoring the production of NADH from NAD+. The velocity of the reaction will eventually go to zero. The reaction will reach equilibrium because of the presence of the enzyme. It is always better to use substrate rather than product to measure enzyme kinetics.
All metabolic pathways must be regulated to maintain homeostasis. The catalytic activity of anenzyme can be controlled allosterically and/or by reversible covalent modification. Provide anexample of each type of regulation (allosteric and reversible covalent modification) in the contextof a metabolic pathway. Be specific, and be sure to explain the rationale behind the regulatorystrategy.
