Final Answer:
The liver responds to F26Bp by inhibiting fruc-tose-2,6-bis-phos-phatase, leading to an increase in fruc-tose-2,6-bis-phos-phate concentration, which activates phos-pho-fruc-tokinase-1, promoting gly-coly-sis.
Step-by-step explanation:
F26Bp, or fruc-tose-2,6-bis-phos-phate, plays a crucial role in regulating gly-coly-sis and gluco-neo-genesis. In response to F26Bp, the liver exhibits a specific regulatory mechanism. F26Bp inhibits fruc-tose-1,6-bis-phos-phatase, an enzyme involved in gluco-neo-genesis. By inhibiting this enzyme, F26Bp prevents the breakdown of fruc-tose-1,6-bis-phos-phate into fruc-tose-6-phos-phate, favoring gly-coly-sis. The increased concentration of F26Bp activates phos-pho-fruc-tokinase-1, a key enzyme in gly-coly-sis. This activation stimulates gly-coly-tic flux, leading to increased ATP production.
