Which of the following conditions will produce active glycogen phosphorylase? AMP АТР Phosphorylation of Serine 14 Glucose Glucose-6-Phosphate Phosphorylation of Serine 14 and AMP Phosphorylation of Serine 14 and ATP
Consider ten glucose molecules that enter a cell. How many ATP can be generated by the complete catabolism of these into CO2 and H2O? If all ten are first incorporated into glycogen, liberated from glycogen, and then fully catabolized into CO2 and H2O, does the ATP tally increase, decrease or stay the same? Consider that 1 UTP = 1 ATP. Explain. Describe the processes which produce ATP and provide a balanced equation of glucose, CO2, H2O and O2
Kinases catalyze the transfer of a phosphate group from a phosphate donor such as adenosine triphosphate (ATP) to a substrate. A well‑known kinase is hexokinase. Hexokinase catalyzes the first step of the glycolysis cycle, and converts glucose to glucose‑6‑phosphate. The reaction of glucose with ATP is shown. The enzyme‑bound base is abbreviated as :B−, and ATP is abbreviated as a diphosphate bonded to adenosine monophosphate (AMP).

The first arrow of the reaction mechanism is drawn for you; draw the remaining curved arrows to show how phosphorylation occurs.
Glucose is phosphorylated to glucose-6-phosphate by hexokinase in the first step of the glycolytic pathway to trap it in the cell, as G6P cannot diffuse across the lipid bilayer. This reaction also decreases the concentration of free glucose, favoring additional import of the molecule. However, this has a postive standard free energy of 3 kcal per mole. To favor this reaction, hydrolysis of ATP is coupled, which has a standard free energy of -7 kcal per mole. Determine the actual free energy change in kcal/mole for the following conditions: Glucose concentration: 4.5 mM ATP conc: 3.79 mM G6P conc. 0.052 mM ADP conc: 0.12 mM inorganic phosphate conc: 1.3 mM temperature: 313 K Ans. in 3 SFs.

The concentration of glucose in your circulatory system is maintained near 5.0 mM by the actions of the pancreatic hormones glucagon and insulin. Glucose is imported into cells by protein transporters that are highly specific for binding glucose. Inside the liver cells the imported glucose is rapidly phosphorylated to give glucose-6-phosphate (G-6-P). This is an ATP-dependent process that consumes 1 mol ATP per mol of glucose. Given the steady-state intracellular concentrations below, calculate the theoretical maximum concentration of G-6-P inside a liver cell at 37 °C, pH = 7.2 when the glucose concentration outside the cell (i.e., [glucoseloutside) is 5.0 mM: ATP = 4.7 mM; ADP = 0.15 mM; P, = 6.1 mM For: ATP + H,O ADP + P + H* AG" = -30.5 kJ/mol and G-6-P + H,0 -→ Glucose + P AG" = -13.8 kJ/mol The glucose phosphorylation reaction is ATP + glucosenside » ADP + glucose-6-phosphate + H+
Assuming that the glycerol 3-phosphate shuttle is operative, a complete oxidation of five molecules of glucose (by a eukaryotic cell) into carbon dioxide and water would produce approximately _________ ATP molecules via oxidative phosphorylation only. (Consider NADH = 2.5 ATP and FADH2 = 1.5 ATP)
Glycolysis is an important pathway for energy production. As such, the enzymes are always present. After eating a meal, blood glucose levels rise drastically, requiring a rapid increase in glycolytic enzyme concentration to metabolize the influx of glucose. When the blood glucose level drops to baseline, the concentration of glycolytic enzymes is reduced in the cell. Question :- Describe one pathway that allows the cell to rapidly increase glycolytic enzyme levels and one pathway that can be used to reduce glycolytic enzyme levels.
