The correct Answer is:
To solve the question "Animals do not synthesize," we will analyze each option provided: ### Step-by-Step Solution: 1. **Analyze Option A: Protein** - Animals can synthesize proteins. They do this by using amino acids, which are the building blocks of proteins. The body can produce some amino acids (non-essential amino acids), while others must be obtained from the diet (essential amino acids). Therefore, animals do synthesize proteins. - **Conclusion**: Option A is incorrect. 2. **Analyze Option B: Vitamins** - Most vitamins cannot be synthesized by animals and must be obtained from their diet. While there are a few exceptions where certain vitamins can be synthesized in small amounts (like Vitamin D in the skin), the majority of vitamins are essential nutrients that animals need to consume. Thus, animals do not synthesize most vitamins. - **Conclusion**: Option B is correct. 3. **Analyze Option C: Glycogen** - Glycogen is a polysaccharide that serves as a form of energy storage in animals. It is synthesized from glucose molecules primarily in the liver and muscles. Therefore, animals do synthesize glycogen. - **Conclusion**: Option C is incorrect. 4. **Analyze Option D: Phospholipids** - Phospholipids are essential components of cell membranes and are continuously synthesized in the body. They are made from fatty acids and glycerol, and thus, animals do synthesize phospholipids. - **Conclusion**: Option D is incorrect. ### Final Answer: The correct answer is **(b) Vitamins**. Animals do not synthesize most vitamins and must obtain them from their diet. ---
