II. Heam is the prosthetic group for the enzyme which catalyses the carboxylation of RuBP in the stroma of chloroplast,
III. The electron carrier between cyt c-oxidase and cyt-c-reductase is attached to inner membrane of mitochondria.
IV. Water spliting reaction in the lumen of thylakoid requires chlorine.
(a) I, II
(b) I, IV
(c) II, III
(d) III, IV

Options

A. I, II
B. I, IV
C. II, III
D. III, IV

Answer

To solve the question, we need to evaluate each of the four statements provided and determine which pairs are correct.

### Step-by-Step Solution:

1. **Evaluate Statement I**:
- **Statement**: Niacin containing coenzymes facilitates the oxidation of malate in the matrix of mitochondria.
- **Analysis**: Niacin (vitamin B3) is a precursor for NAD and NADP, which are essential coenzymes in metabolic processes. The oxidation of malate occurs in the mitochondria, specifically in the Krebs cycle, where NAD+ is reduced to NADH.
- **Conclusion**: This statement is **correct**.

2. **Evaluate Statement II**:
- **Statement**: Heme is the prosthetic group for the enzyme which catalyzes the carboxylation of RuBP in the stroma of chloroplast.
- **Analysis**: The enzyme that catalyzes the carboxylation of ribulose bisphosphate (RuBP) is called Rubisco. The prosthetic group of Rubisco is not heme; it is a complex enzyme that does not utilize heme as a prosthetic group.
- **Conclusion**: This statement is **incorrect**.

3. **Evaluate Statement III**:
- **Statement**: The electron carrier between cytochrome c oxidase and cytochrome c reductase is attached to the inner membrane of mitochondria.
- **Analysis**: The electron transport chain components, including cytochrome c, are located in the inner mitochondrial membrane. However, the electron carrier that connects cytochrome c oxidase and cytochrome c reductase is actually located in the intermembrane space, not the inner membrane itself.
- **Conclusion**: This statement is **incorrect**.

4. **Evaluate Statement IV**:
- **Statement**: Water splitting reaction in the lumen of thylakoid requires chlorine.
- **Analysis**: The process of photolysis of water during photosynthesis occurs in the thylakoid lumen and does involve the presence of chlorophyll and other components, but it does not specifically require chlorine. Instead, it primarily requires light energy and water.
- **Conclusion**: This statement is **incorrect**.

### Summary of Statements:
- Statement I: Correct
- Statement II: Incorrect
- Statement III: Incorrect
- Statement IV: Incorrect

### Final Answer:
The only correct statement is I. Therefore, the correct pair of statements is **(a) I, II**. However, since II is incorrect, the correct answer should actually be **none of the pairs** listed.
