Explain why several biochemical pathways start by putting a coenzyme A onto the molecule that initiates the pathway.

The products of a pathway, or the products of specific reactions in the pathway, will often inhibit upstream regulatory enzymes in that pathway. That makes sense - if the products of a pathway are abundant, then the pathway can be shut off to save energy or divert molecules into other pathways. We can use a similar rule of thumb to predict whether a pathway will be active in different biological states. For example, the liver stores glucose (in the form of glycogen), and will release glucose into the bloodstream when blood sugar levels drop. This glucose can come from the synthesis of glucose or breakdown of stored glycogen. This is important for maintaining blood sugar levels. What would you predict is the relationship between blood sugar levels and glycogen phosphorylase enzyme activity? A positive relationship (when blood sugar levels are high, glycogen phosphorylase activity is also high). A negative relationship (when blood sugar levels are high, glycogen phosphorylase activity…

why is the pathway for biosynthesis of a biomolecule at least partially different than the pathway for catabolism.

if there are twelve different intermediate products produced in the stage of a metabolic within a cell, we can expect that there

The natural enzyme is recreated by mixing isolated regulatory and catalytic subunits of ATCase. What biological relevance does this observation have?

Explain why enzymes may need an organic cofactor derived from a vitamin( i.e.,a coenzyme) or mineral cofactor to function

Among the following biochemical condition, which condition describes forward (spontaneous) reaction? a) Q >> Keq b) ΔΔG=0 c) Keq=1 d) Q << Keq

Explain why it is normal for two enzymes that have vastly different amino acid sequences, still be able to catalyze similar enzymatic reactions.

Why can’t an enzyme use an induced fit mechanism to achieve catalytic perfection?
