| Question | Answer |
|---|---|
| If a solution is 9% NaCl, and a cell is 20% NaCl, will the cell shrink, swell, or stay the same? | The Cell will swell |
| If the solution is 25% glucose, and the cell is 10% glucose, is the cell hypertonic, hypotonic, or isotonic? | The cell is hypotonic. |
| Is the body in osmotic equilibrium or disequalibrium? | The body is in osmotic equilibrium. |
| Are the amounts of water the same in the intracellular fluid and in the interstitial fluid? | no |
| Is the body in chemical equilibrium or disequilibrium? | The body is in chemical disequilibrium. |
| Is the sodium potassium pump an example of a uniport, cotransport symport, or cotransport antiport? | The sodium potassium pump is an example of cotransport antiport. |
| Is GLUT transport passive or active transport? | GLUT is passive transport. |
| Is the potassium levels at a higher concentration inside or outside of our cells? | We have higher potassium levels inside our cells. |
| What ion is required in SGLT to transport glucose across the membrane? | A sodium ion is required to transport glucose across the membrane in SGLT. |
| In GLUT, is glucose moving with or against its concentration gradient? | In GLUT, glucose is moving with its concentration gradient. |
