can you please help me understand this question: The Sodium-Potassium Pump: sodium -driven glucose symport. where is the high concentration of sodium and where is the high concentration of glucose and which direction are they moving. who is doing facilitated diffusion and whos doing active transport?
Homework Answers
Glucose can’t move against its concentration gradient (from low to high concentration) by itself. In animal cells, glucose is co-transported into the cell with sodium ions through facilitated diffusion. There’s a very high concentration of sodium ions outside the cell, so the concentration gradient will want to move sodium from the outside of the cell (high concentration) to the inside (low concentration). As the sodium ions move in the “correct” direction, from outside the cell...Glucose can’t move against its concentration gradient (from low to high concentration) by itself.

33) Which of the following is most likely true of a protein that cotransports glucose and sodium ions into the intestinal cells of an animal? A) Sodium and glucose bind to the same site on the cotransporter. B) Transport of glucose against its concentration gradient provides energy for uptake of sodium ions against the electrochemical gradient. C) Sodium ions can be transported whether or not glucose is present outside the cell, but glucose transport requires cotransport of sodium ions. D)...

Please help me! You have identified a new transporter involved in the movement of sodium and calcium. Describe an experiment to determine whether this transporter is a pump or a secondary transporter. –Key difference: A pump requires energy that is not coupled to a concentration gradient. Secondary transporters use the power of one concentration gradient to drive transport of a different molecule against its concentration gradient. –Experiment: ??????? –Expectations: ??????
