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.

spiders belong to a group of arachnids.

arachnids have the following traits :

they have two body parts.

they have eight legs unlike insects which have 6 legs.

they have no wings.

these traits distinguish them from insects.

the information that antonio is doubting us the statement that spiders differences are as a result of being first to evolve.

this is because the evolution of one species is independent of the other species.

the generally accepted parts of modern cell theory include: all known living things are made up of one or more cells. all living cells arise from pre-existing cells by division. the cell is the fundamental unit of structure and function in all living organisms.
