The correct Answer is:
To determine which element is absent in proteins, we can analyze the components that make up proteins and amino acids. ### Step-by-step Solution: 1. **Understand the Composition of Proteins**: - Proteins are made up of amino acids, which are the building blocks of proteins. 2. **Identify the Elements in Amino Acids**: - Amino acids generally contain the following elements: - Carbon (C) - Hydrogen (H) - Nitrogen (N) - Oxygen (O) - Some amino acids also contain Sulfur (S), such as methionine. 3. **Examine the Options**: - (a) Carbon (C): Present in all amino acids. - (b) Nitrogen (N): Present in the amino group of amino acids. - (c) Phosphorus (P): Not present in proteins. - (d) Sulfur (S): Present in some amino acids. 4. **Conclusion**: - Since phosphorus (P) is not a component of proteins, the correct answer is (c) Phosphorus. ### Final Answer: (c) P
