Describe, with specific detail (step-by-step cause/effect) and drawings, how glucose is transported across the membrane via Passive Transport. Include concentrations gradients, membrane proteins, direction of flow and any other details you feel are relevant Name two kinds of proteins that are involved in the movement of glucose into the cell.
The key step in the metabolism of glucose for energy is the isomerization of glucose-6-phosphate (G6P) to fructose-6-phosphate (F6P): G6P F6P K = 0.510, at 298K. Calculate Delta G when Q, the [F6P|/[G6P] ratio, equals 10.0. times 10 J/mol Enter your answer in scientific notation.

Carbohydrates in the diet Triglycerides in the diet Protein and amino acids in the diet Stored glycogen in the liver or muscle Conversion of certain amino acids to glucose Conversion of fatty acids to glucose Amino acid pool in the liver
One step in the metabolism of glucose is depicted below. Which statement best describes how the equilibrium system would respond if the amount of dihydroxyacetone phosphate is decreased? fructose 1,6-bisphosphate dihydroxyacetone + glyceraldehyde phosphate 3-phosphate
All mechanisms of glucose metabolism begin with glycolysis and produce 2 pyruvates, 2 ATP and 2 NADH. Make a table comparing aerobic and anaerobic metabolism (after glycolysis) to describe how pyruvate is metabolized. Columns: Cell Respiration, Lactic Acid, Alcohol Fermentation Rows: Where (in the cell) does pyruvate go? What happens to pyruvate (explain in step by step detail)? Is pyruvate oxidized or reduced? What energy-storing molecules are made? What energy-storing molecules are used? What byproducts str produced (CO2 or H2O)?...
