I filled in what I thought the answers are but I'm really not sure.
Fill in the blanks to complete statements about the regulation of one key step in glycolysis (conversion of Fructose 6-phosphate to fructose 1, 6 biphosphate). Use words from this list but keep in mind that not all words may be used and some words may be used more than once: glucose, glycolysis, gluconeogenesis, high, low, ATP, insulin, glucagon, phosphorylate, dephosphorylate, fructose 2, 6 biphosphate, PFK-1, PFK-2, FBPase-1, FBPase-2, hexokinase, activated, inhibited, active, inactive, breakdown, formation When the concentration of F26BP is high, FBPase-1 is and the pathway is active. If glucagon is present, this means that the concentration of glucose is. In this situation, gluconeogenesis will be. Glucagon results in the activation of protein kinase A (PKA). PKA will the bifunctional protein. In this state, the part of the bifunctional protein will be activated. This will result in the of F26BP. As a result, the enzyme PFK-1 will be and the pathway will be inhibited.Explanation / Answer
1. When the concentration of the F26BPis high, FBPase is inhibited and the Glycolysis pathway is active.
2. If glucagon is present, this means that the concentration of glucose is low . In this situation, gluconeogenesis will be active . Glucagon results in the activation of protein kinase A (PKA). PKA will phosphorylate the bifunctional protein. In this state, the FBPase-2 part of the bifunctional protein will be activated. This will result in the breakdown of the F26BP. As a result, the enzyme PFK-1 will be inhibited and the Glycolysis pathway will be inhibited
