<span>An oxidation-reduction (redox) reaction is a type of chemical reaction that involves a transfer of electrons between two species. An oxidation-reduction reaction is any chemical reaction in which the oxidation number of a molecule, atom, or ion changes by gaining or losing an electron.</span>

Sunny weather does seem to be broadly correlated with a larger surplus on the international tourism balance, while worse weather is associated with a tourism deficit. This confirms that, as expected, overall there is a net flow of tourists from colder to warmer countries.

Which statement about control of glycogen metabolism is INCORRECT? Which statement about control of glycogen metabolism is INCOR
GuDViN [60]

Answer:

Glycogen synthase is phosphorylated at only one site.

Explanation:

Glycogen synthase has multiple sites where phosphorylation can occur. Glycogen synthase may have 9 or more sites where it can be phosphorylated as a result of which it's activity is down regulated. It simply means that the regulation of this enzyme does not occur through binary on/off switching, in fact it's activity is modulated over a wide range in response to various signals.

In contrast to glycogen phosphorylase which gets activated when it is phosphorylated at it's serine residues, glycogen synthase gets inactivated by phosphorylation.

As soon as another enzyme GSK3β phosphorylates glycogen synthase, it gets inactivated as a result of which glycogen synthesis halts in the liver.
