Enzyme Control of Metabolic Pathways
... It is essential that the various biochemical processes occurring within an organism are adaptable. This means that the rates of biochemical reactions need to vary in response to change. In humans, for instance, these reactions need to cope with a sudden abundance of glucose in cells after a carbohyd ...

Cell Biology
... Enzymes are made by all living cells. Their function in a cell is to work as a BIOLOGICAL CATALYST. A catalyst is a substance which SPEEDS UP A CHEMICAL REACTION and REMAINS UNCHANGED at the end of the reaction. Without enzymes, the reactions which go on inside ALL LIVING CELLS would be so slow that ...

For TLR4, the MyD88-independent pathway may be mediated by MyD88 adaptor-like (Mal, also known as TIRAP), as it has been demonstrated that Mal is recruited to TLR4, and is involved in NF-B activation (25, 26). Activation of NF-B by the MyD88-dependent pathway can proceed via recruitment of IL ...
