The Cori Cycle is responsible for removing excess Lactic acid or Lactate from the muscle. It is then uptaken by the Liver where it is converted back into Pyruvate, then into Glucose again. This video explains how!

The Michaelis-Menten Model Accounts for the Kinetic Properties of Many Enzymes - Biochemistry - NCBI Bookshelf
The primary function of enzymes is to enhance rates of reactions so that they are compatible with the needs of the organism. To understand how enzymes function, we need a kinetic description of their activity. For many enzymes, the rate of catalysis V0, which is defined as the number of moles of product formed per second, varies with the substrate concentration [S] in a manner shown in Figure 8.11. The rate of catalysis rises linearly as substrate concentration increases and then begins to level off and approach a maximum at higher substrate concentrations. Before we can accurately interpret this graph, we need to understand how it is generated. Consider an enzyme that catalyzes the S to P by the following pathway: Figure 8.11Michaelis-Menten KineticsA plot of the reaction velocity (V0) as a function of the substrate concentration [S] for an enzyme that obeys Michaelis-Menten kinetics shows that the maximal velocity (Vmax) is approached asymptotically. The Michaelis constant (KM) is the substrate concentration yielding a velocity of Vmax/2.

During recent decades, bewildering progress has occurred in the field of Molecular and Cellular Biochemistry. Progress has been extraordinarily rapid primarily because of the challenge for finding solutions to a wide variety of diseases and the availability of new techniques for monitoring biochemical processes. This has resulted in a voluminous and complex literature in the field of biochemical medicine so that there is a clear need for the synthesis and analysis of the continuing expansion of valuable data. It was thus considered appropriate to initiate a new series of monographs, each dedicated to a specialized area of investigation, encompassing molecular and cellular processes in health and disease. Most of the biochemical scientists have devoted their energies in understanding the fundamentals of biochemistry and indeed impressive advances have been made in the past. However, the full potential for explanation has been hampered by the concept of universality of biochemical reactions occurring in the cell. In view of the fact that each organ in the body performs a distinct function, it is now beginning to be realized that each cell type is unique in its need to survive and perform its specific function. Accordingly, the aspect of individualty is receiving increased attention for revealing new avenues in the study of pathophysiology of cellular abnormalities.
