g Fructose 2,6-bisphosphate is a regulator of glycolysis and a regulator of gluconeogenesis.

Fructose 2,6-bisphosphate is a positive regulator of glycolysis and a negative regulator of gluconeogenesis.

Explanation:

Fructose-2,6-bisphophate is an allosteric effector of the enzymes phosphofructokinase-1, PFK-1 and fructose-1,6-bisphosphatase, FBPase-1.

When fructose-2,6-bisphosphate binds to its allosteric site on PFK-1, it increases the enzymes affinity for its substrate fructose-6- phosphate and reduces its affinity for ATP and citrate, its allosteric inhibitors. This favors favors glycolysis.

However, binding of fructose-2,6-bisphosphate on its allosteric site on FBpase-1 has the opposite effect on it. It reduces its affinity for its substrate, fructose-1,6-bisphosphate, thereby inibiting gluconeogenesis.

there are mainly three domains in biological classification namely; archaea, bacteria, and eukarya.

archaea includes all the prokaryotic cells which are characterized by their lipid membranes. they have branched hydrocarbon which is attached to glycerol through an ether linkage.

bacteria includes all the prokaryotic cells, the cell membrane of which are made up of the unbranched fatty acid chain. in addition, they are attached to glycerol through an ester bond.

eukarya includes all the eukaryotic cells, that is, the cells contain a nucleus and other membrane-bound cell organelles.

they can be autotrophic as well as heterotrophic, unicellular as well as multicellular

they include kingdoms like protista, plantae, animalia, fungi et cetera.
