Phosphofructokinase catalyzes the phosphorylation of fructose 6‑phosphate to fructose 1,6‑bisphosphate in glycolysis. Fructose 1
umka2103 [35]

Answer:

d. increases PFK activity, decreases FBPase activity

Explanation:

Fructose-2,6-bisphophate is formed by the phosphorylation of fructose-6-phosphate catalyzed by phosphofructokinase-2, PFK-2.

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

Fructose-2,6-bisphophate has opposite effects on the enzymes, PFK-1 and FBPase. When it binds to the allosteric site of the enzyme, PFK-1, it increases the enzymes's activity by increasing its affinity for its substrate fructose-6-phosphate and reduces its affinity for its allosteric inhibitors ATP and citrate. However, when it binds to FBPase, it reduces its activity by reducing its affinity for glucose, its substrate

Consider the aldol-dehydration reaction. Draw the two possible products of the reaction between benzaldehyde and methylethylketo
Dafna1 [17]

Solution :

An $\text{aldol condensation}$ reaction is a type of \text{condensation reaction} in organic chemistry where the enol or an enolate ion reacts with the carbonyl compound and forms a $\beta$-hydroxyaldehyde or a $\beta$-hydroxyketone, and then followed by a dehydration to give conjugated enone.  

Benzaldehyde reacts with methylketone and forms two products:
