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
The question pertains to cancer cells exhibit an altered energy metabolism. The breakdown of one glucose yields two molecules of ATP via glycolysis so why thorough aerobic conditions is there such an abundance of ATP?
Which of the answer choices is true about ATP synthase? Select all that apply. O ATP synthase makes a total of four ATP molecules in glycolysis. O ATP synthase is an important enzyme in the citric acid cycle. ATP synthase is an integral membrane protein. Under aerobic conditions, the F1 (globular) portion of ATP synthase catalyzes a catabolic reaction. V ATP synthase is a transport protein. O ATP synthase is an enzyme. ATP synthase relies on an electrochemical gradient of sodium ions to catalyze the formation of ATP.
In hepatocytes, the enzyme glucokinase catalyzes the ATP-coupled phosphorylation of glucose. Glucokinase binds both ATP and glucose, forming a glucose-ATP-enzyme complex. The enzyme then transfers the phosphoryl group directly from ATP to glucose. Select the advantages of phosphoryl group transfer compared to hydrolysis and subsequent phosphorylation? Glucokinase increases the transition state energy, favoring glucose phosphorylation. Reaction intermediates do not need to be present in excess. The process takes advantage of the high phosphoryl group transfer potential of ATP. ATP hydrolysis is thermodynamically unfavorable compared to group transfer.

Review the following statements and discuss whether each one is correct, incorrect or partially correct: Con In the presence of oxygen glycolysis can yield a net production of 6 molecules of ATP per molecule of glucose. In the presence of oxygen glycolysis can yield a net production of 8 molecules of ATP per molecule of glucose. In the absence of oxygen glycolysis can yield a net production of 2 molecules of ATP per molecule of glucose. In the absence of oxygen glycolysis can yield a net production of 4 molecules of ATP per molecule of glucose
We have discussed the aerobic metabolism of glucose extensively in this class. To capture and use the energy in glucose to make ATP, we must utilize 4 different sequential pathways/steps. Starting with one glucose molecule and eventually ending with CO, H;O and ATP, list the 4 pathways/steps in order and tell me what molecules enter each pathway, and what the final products of each pathway are.
