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.
1 Glucokinase has a lower affinity for glucose than the other hexokinases. 2  Glucokinase changes conformation and/or function in parallel with rising glucose concentrations in the physiologically important range of 4â10 mmol/L (72â180 mg / dl).3  It is half-saturated at a glucose concentration of about 8 mmol/L (144 mg/dl).
