Question

1. what do the chemical bonds represent?

for question 4 - 6, use the diagram below and your knowledge of biology.
starch

1. which compound is complex?__________ explain.
2. which molecule is simple?__________ explain.
3. explain the relationship between starch and glucose.__________

Explanation:

• Question 4: Starch is a complex compound. It is a polysaccharide made up of many glucose units linked together. The diagram shows a long - chain structure for starch, indicating its complexity as a macromolecule formed by polymerization of simple units.
• Question 5: Glucose is a simple molecule. It is a monosaccharide, the basic unit of carbohydrates. The diagram shows a single - ring structure for glucose, which is characteristic of simple sugar molecules.
• Question 6: Starch is a polymer of glucose. Glucose units are joined together through glycosidic bonds to form starch. Starch serves as a storage form of glucose in plants. When the plant needs energy, starch can be broken down into glucose molecules through hydrolysis reactions.

Answer:

• 4. Starch. It is a polysaccharide (long - chain polymer) made of many glucose units.
• 5. Glucose. It is a monosaccharide (single - unit sugar).
• 6. Starch is a polymer of glucose. Glucose units are linked to form starch, and starch can be broken down into glucose for energy use.
