Cyclin-dependent kinases are special molecules that facilitate the progression of a cell through the cell cycle. Many molecules such as p53 regulate the cell cycle. An unregulated cell cycle can lead to rapid growth of the cell that may eventually lead to cancer. In lab, you are working with a […]

Ribose is the initial substrate for the synthesis of AMP and GMP (purine nucleotides and the precursors of ATP and GTP respectively). The following diagram is a simplified overview of this overall metabolic pathway. The numbers refer to enzymatically-catalyzed steps in the pathway. a) Which enzyme is most likely to […]

While studying the Michaelis – Menton kinetics of enzymes in the TCA cycle, the synthetic hydrocarbon malonate was shown to act as a competitive inhibitor of one of the enzymes. At first, the identity of the inhibited enzyme was unknown but further tests revealed that this inhibited TCA enzyme was […]
