What will be true for the effects of parathyroid glands on the tissues shown in the given diagram?
1. Only I and II are correct
2. Only I and III are correct
3. Only II and III are correct
4. I, II and III are correct
| I: | In bone, PTH enhances the release of calcium from the large reservoir contained in the bones. |
| II: | In the kidney, PTH stimulates reabsorption of calcium but inhibits the reabsorption of phosphate \((HPO^{2-}_4)\) from the tubular fluid. |
| III: | It activates vitamin D, which in turn enables intestinal epithelium to absorb calcium. |

The given figure shows the mechanism of action of FSH on its target cells.
1. Only I is correct
2. Only II is correct
3. Both I and II are correct
4. Both I and II are incorrect
| I: | FSH is hydrophilic and hence cannot enter the cell and therefore acts via a second messenger. |
| II: | The second messenger will cause physiological responses after binding to a receptor present in the nucleus of the cells and then influencing the level of gene expression in the target cell. |
1. Only I is correct
2. Only II is correct
