Generally the smaller cell

Options

A. The larger the nucleus
B. The smaller the nucleus
C. It will be more metabolically active
D. It will be less metabolically active

Explanation

**Step-by-Step Solution:**

1. **Understanding Cell Size and Metabolic Activity:**
- Smaller cells generally have a higher metabolic activity compared to larger cells. This is primarily due to their size and the surface area available for exchange processes.

2. **Surface Area to Volume Ratio:**
- The surface area to volume ratio is crucial in determining how efficiently a cell can exchange materials with its environment. Smaller cells have a higher surface area relative to their volume compared to larger cells.

3. **Implications of Higher Surface Area to Volume Ratio:**
- A higher surface area to volume ratio means that there is more membrane area available for the exchange of ions and molecules. This facilitates quicker and more efficient transport of substances into and out of the cell.

4. **Metabolic Activity:**
- Since smaller cells can exchange materials more effectively, they tend to be more metabolically active. This means they can carry out cellular processes at a faster rate compared to larger cells, which may have limitations due to their lower surface area to volume ratio.

5. **Conclusion:**
- Therefore, smaller cells are generally more metabolically active than larger cells due to their higher surface area to volume ratio, which allows for more efficient exchange of materials.

**Final Answer:**
Smaller cells are generally more metabolically active than larger cells because they have a higher surface area to volume ratio, allowing for more efficient exchange of materials.
