In October, the sun shines for at least 7 hours per day but brace yourself for rain as there are on average 6 days of rainfall during the month. Around 70mm of rain falls throughout October with temperatures generally settling between 14 Â°C and 26 Â°C.
For example, ATP allosterically inhibits phosphofructokinase, but it activates the functionally opposite enzyme fructose-1,6-bisphosphatase (see slide 7.5.3). Similarly, phosphorylation inhibits glycogen synthase but activates glycogen phosphorylase, which degrades glycogen (slide 8.4.1).llosteric regulation of phosphofructokinase by AMP. To accomplish the stimulation of phosphofructokinase, AMP interacts with the enzyme at an allosteric binding site, that is, a site that is distant and functionally distinct from the active site.
Glucokinase (hexokinase D) is a monomeric cytoplasmic enzyme found in the liver and pancreas that serves to regulate glucose levels in these organs. Glucokinase is used in the first step of the metabolism of glucose, during this step the phosphorylation of glucose by ATP generates glucose-6-phosphate and ADP.lucokinase vs. Other Hexokinases: Glucokinase is unique from other hexokinase in kinetic properties and is coded by a different gene. The difference of glucokinase from the other hexokinases is that glucokinase has a lower affinity, thus a higher Km, for glucose.
