**ACTIVITY 1.1.1 HOMEWORK/CLASS WORK (INDIVIDUAL WORK)** **MINERALS** **Name:** [Your Name] --- ### 1. **Any THREE mineral elements that are required for the formation of cell membranes:** - **Phosphorus (P):** Essential component of phospholipids, which are the main building blocks of cell membranes. - **Calcium (Ca):** Plays a role in maintaining membrane stability and signaling. - **Potassium (K):** Important for maintaining the electrochemical gradient across cell membranes. ### 2. **Any THREE mineral elements that are required for chlorophyll formation:** - **Magnesium (Mg):** Central atom in the chlorophyll molecule. - **Nitrogen (N):** Integral part of the chlorophyll structure. - **Iron (Fe):** Involved in enzyme function necessary for chlorophyll synthesis. ### 3. **Any THREE mineral elements that are required for the formation of strong bone and teeth:** - **Calcium (Ca):** Primary mineral that provides strength and structure to bones and teeth. - **Phosphorus (P):** Works with calcium to build and maintain bone structure. - **Magnesium (Mg):** Supports bone density and plays a role in bone formation. ### 4. **Any TWO mineral elements that are required for the formation of nucleic acids:** - **Phosphorus (P):** Constituent of the phosphate backbone in DNA and RNA. - **Magnesium (Mg):** Facilitates the stabilization of nucleic acid structures. ### 5. **Any TWO mineral elements that are required for the formation of Proteins:** - **Sulfur (S):** Present in certain amino acids like cysteine and methionine, which are building blocks of proteins. - **Zinc (Zn):** Acts as a catalytic agent in protein synthesis and function. ### 6. *(This question appears to be missing in the provided list)* ### 7. **ONE mineral element that forms the central atom of chlorophyll:** - **Magnesium (Mg):** The central metal ion in chlorophyll molecules, essential for capturing light energy. ### 8. **ONE mineral element that is a component of haemoglobin:** - **Iron (Fe):** Integral part of haemoglobin, allowing it to transport oxygen in the blood. --- **Note:** Minerals play diverse and crucial roles in various biological processes. Ensuring an adequate intake of these minerals through a balanced diet is essential for maintaining overall health and proper bodily functions.
