Endoenzymes generally act at

Options

A. Acidic pH
B. Alkaline pH
C. neutral pH
D. Any pH.

Answer

**Step-by-Step Solution:**

1. **Understanding Endoenzymes:**
- Endoenzymes are enzymes that function within the cell. They are synthesized and act inside the cellular environment, catalyzing biochemical reactions necessary for cellular processes.

2. **Identifying the pH Preference:**
- Enzymes, including endoenzymes, have an optimum pH at which they function most effectively. This pH is crucial for maintaining the proper shape and charge of the enzyme's active site.

3. **Examples of Endoenzymes:**
- Two examples of endoenzymes are hexokinase and glycogen synthase. These enzymes play vital roles in metabolic pathways, such as glycolysis and glycogen synthesis.

4. **Determining the Optimum pH:**
- The optimum pH for many endoenzymes is typically neutral (around pH 7). Deviations from this pH can lead to changes in the ionization state of the amino acid side chains, which can affect enzyme activity.

5. **Conclusion:**
- Based on the information gathered, the correct answer to the question "Endoenzymes generally act at" is **neutral pH**.

**Final Answer: Neutral pH**
