Which of the following is the correct pair

Options

A. DNA synthesis — Ribosomes
B. Protein synthesis — Smooth E.R.
C. Aerobic respiration — Cristae
D. Suicidal sacs — Dictyosomes

Explanation

To solve the question "Which of the following is the correct pair?", we will analyze each option provided and determine which one is accurate based on our knowledge of cell biology.

### Step-by-Step Solution:

1. **Identify the Options**: We need to look at the four options given in the question. Although the options are not explicitly listed here, we will analyze the common pairs related to cell functions.

2. **Evaluate DNA Synthesis**:
- DNA synthesis occurs in the **nucleus** of the cell.
- Ribosomes are responsible for **protein synthesis**, not DNA synthesis.
- Therefore, if any option states that DNA synthesis occurs in ribosomes, it is incorrect.

3. **Evaluate Protein Synthesis**:
- Protein synthesis primarily occurs on **ribosomes**.
- Ribosomes can be found freely in the cytoplasm or attached to the **rough endoplasmic reticulum (RER)**.
- If an option states that protein synthesis occurs in the **smooth endoplasmic reticulum**, it is incorrect, as the smooth ER is involved in lipid synthesis and detoxification, not protein synthesis.

4. **Evaluate Aerobic Respiration**:
- Aerobic respiration takes place in the **mitochondria** of the cell.
- The inner membrane of the mitochondria contains **cristae**, which are folds that increase the surface area for the electron transport chain.
- If an option states that aerobic respiration occurs in the cristae, this is correct.

5. **Evaluate Societal Sex and Dictogerms**:
- The term "Dictogerms" is not typically associated with societal sex in biology.
- Lysosomes are known as the "digestive system" of the cell, containing hydrolytic enzymes that break down waste materials and cellular debris.
- If an option incorrectly pairs lysosomes with societal sex, it is also incorrect.

6. **Conclusion**:
- After evaluating all the options, the correct pair is related to aerobic respiration occurring in the cristae of the mitochondria. Therefore, the answer is option C.

### Final Answer:
The correct pair is **C: Aerobic respiration - Cristae**.
