Regulation of hexokinase 4

Hexokinase iv regulation mechanism. Download the study materials here- Mammalian hexokinase IV, also referred to as glucokinase, differs from other hexokinases in kinetics and functions. The location of the phosphorylation on a subcellular level occurs when glucokinase translocates between the cytoplasm and nucleus of liver cells. Glucokinase can only phosphorylate glucose if the concentration of this substrate is high enough; its Km for glucose is 100 times higher than that of hexokinases I, II, and III. Hexokinase […]

The Cell Cycle and its Regulation

Your cells have to divide when you’re growing, to heal wounds, and to replace dead cells. But how do cells know when to divide and when not to divide? We can’t have cells just growing willy-nilly! That’s what cancer is, and that’s bad. Luckily, cells obey something called the cell cycle, which is regulated by a variety of signaling molecules, which tell the cell when to divide and when to chill out. Let’s look at the phases […]

Regulation of Gene Expression: Operons, Epigenetics, and Transcription Factors

We learned about gene expression in biochemistry, which is comprised of transcription and translation, and referred to as the “central dogma” of molecular biology. But how is this process regulated? How does a cell know which genes to express and when? Well it’s pretty complicated, but let’s just get our feet wet by looking at operons, epigenetics, and transcription factors!
