|
In the regulation of glycolysis, ____ produced by enzyme ____ will act as ____ effector to accelerate the process.
|
|
Fructose 1, 6-bisphosphate; phosphofructokinase 1; positive
|
|
|
Fructose 2, 6-bisphosphate; phosphofructokinase 2; positive
|
|
|
Fructose 1, 6-bisphosphate; fructose 1, 6-bisphosphatase; negative
|
|
|
Fructose 2, 6-bisphosphate; fructose 2, 6-bisphosphatase; negative
|
Explanation:
Detailed explanation-1: -An increase in fructose 2, 6-bisphosphate stimulates the activity of phosphofructokinase, increases glycogen synthesis and inhibits gluconeogenesis.
Detailed explanation-2: -Fructose 2, 6-bisphosphate (Fru-2, 6-P2) is the most potent stimulator of 6-phosphofructo-1-kinase (PFK-1), a key enzyme of glycolysis.
