Answer:

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.

Answer:

The most appropriate answer would be The cell will not make functional proteins from that mRNA strand.

The amino acid sequence of the proteins is derived from the nucleotide sequence of the mRNA (messenger ribonucleotide).

If the sequence of mRNA is miscopied, it will change the sequence of amino acids of the protein.

Consequently, the protein may become non-functional.

As a rare occurrence, a person can become infected with the flu by touching a surface or object contaminated with the influenza virus and then touching the mouth, nose, or eyes.

Pigs sometimes transmit influenza H1N1 virus to people, primarily pig farmers and veterinarians.
