Answer:
b. Phosphofructokinase; Fructose-1,6-bisphosphatase
Explanation:
Glucagon is a hormone which functions to initiate gluconeogenesis whwreas insulin functions to initiate glycolysis.
Fructose-2,6-bisphosphate (F26BP) is an allosteric regulator of the <em>glycolytic and gluconeogenic enzymes phosphofructokinase-1 (PFK-1) and fructose-1,6-bisphosphatase (FBPase-1).</em>
It stimulates glycolysis and inhibits gluconeogenesis by binding to its allosteric site on phosphofructokinase-1 reducing its affinity for the allosteric inhibitors ATP and citrate .
It is formed by phosphorylation of fructose-6-phosphate catalyzed by <em>phosphofructokinase-2</em> and is broken down by <em>fructose-2,6-bisphosphatase </em>which are two separate enzymatic activities of a single, bifunctional protein (PFK-2/FBPase-2).
Phosphorylation of PFK-2/FBPase-2 due to glucagon release enhances its FBPase-2 activity thereby stimulating gluconeogenesis and inhibiting glycolysis.
Dephosphsorylation of PFK-2/FBPase-2 due to insulin release enhances its PFK-2 activity, thereby stimulating glycolysis and inhibiting gluconeogenesis.
Water vapour and gases such as oxygen and carbon dioxide are able to move across the egg shell through small openings called pores. The egg contains all the nutrients that the developing chick needs during the three weeks of incubation period.
Answer: the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature.
Explanation: Relative humidity (RH) is the ratio of the partial pressure of water vapor to the equilibrium vapor pressure of water at a given temperature. Relative humidity depends on temperature and the pressure of the system of interest. The same amount of water vapor results in higher relative humidity in cool air than warm air. A related parameter is the dew point.
