Coenzyme Matching: List I and List II Explained
This question requires matching coenzymes from List I with their corresponding biochemical roles or transferred groups from List II.
Key Coenzyme Functions
- A. Coenzyme Q (Ubiquinone): This coenzyme is crucial in the electron transport chain, acting as a mobile carrier of electrons and protons. Therefore, it is associated with IV. Hydrogen atoms.
- B. Biocytin: Biocytin is related to biotin, a vitamin essential for carboxylase enzymes. These enzymes facilitate the transfer of carboxyl groups, essentially involving III. Carbon Dioxide ($CO_2$) in metabolic reactions.
- C. Pyridoxal Phosphate (PLP): As the active form of Vitamin B6, PLP is a vital cofactor in amino acid metabolism. It participates in reactions involving the transfer and modification of I. Amino groups.
- D. Thiamin Pyrophosphate (TPP): This derivative of Vitamin B1 is a key cofactor for enzymes involved in carbohydrate metabolism. It notably functions in reactions involving the transfer of II. Aldehyde groups (e.g., in decarboxylation).
Summary of Matches
Based on the biochemical roles:
- Coenzyme Q matches with Hydrogen atoms (IV).
- Biocytin matches with Carbon Dioxide (III).
- Pyridoxal Phosphate matches with Amino groups (I).
- Thiamin Pyrophosphate matches with Aldehyde (II).
The correct matching is A-IV, B-III, C-I, D-II.
| List I Item | List II Match | Explanation |
|---|---|---|
| A. Coenzyme Q | IV. Hydrogen atoms | Electron transport chain function. |
| B. Biocytin | III. Carbon Dioxide | Biotin-dependent carboxylation. |
| C. Pyridoxal Phosphate | I. Amino groups | Amino acid metabolism cofactor. |
| D. Thiamin Pyrophosphate | II. Aldehyde | Carbohydrate metabolism, aldehyde transfer. |
Thus, the correct option representing the matches A-IV, B-III, C-I, D-II is determined.
