KEY ance Movement Facilitaced n/Out of Cell Osygen Passive N 0 Calkium ion Passive Yes Sodium ionYes Glucose Pasive Yes Carbon Passive Dioxide No Outside of Inside of Instructions Using the key and diagram, determine if each substance moves in or out of the cell. Wrice "in or "our" in the space perovided for th given substance. Next, use an arrow to show the direction of movement of two of each of the substances theough the membeane, and where in the membrane they move through. Hint- channel proteins have symbols indicat- ing the substance they transportExplanation / Answer
Answer.
Explanation: In passive transport, the substances move from higher to lower concentration. So, oxygen, calcium and glucose move inside the cell because their number was more outside the cell. CO2 moved out because its number was more inside and movement has to occur from higher concentration to lower concentration.
Active transport utilises energy and occur from lower to higher concentration.
Answer. Sodium ions are more inside the cell than outside. Active transport occuring, means movement will occur from lower concentration to higher concentration as it utilises energy. It's transport will occur through facilitated diffusion that utilises the carrier proteins. Thus,
Outside------>carrier proteins(Na+) - - - > inside the cell, maintaining sodium-potassium pump in the body.
Similarly, Ca also moves the same way, triggering various biochemical events inside the cell.
The movement of gases does not requires any carrier or channel protein. They pass simply through diffusion.
