Write the formulae of glucose, sugar and starch.

Explanation

To answer the question regarding the formulae of glucose, sugar, and starch, we can break it down step by step:

### Step 1: Understand the chemical formula for glucose.
- Glucose is a simple sugar and its chemical formula is **C₆H₁₂O₆**. This indicates that one molecule of glucose contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.

### Step 2: Identify the chemical formula for sugar.
- The term "sugar" can refer to various types of sugars, but when we talk about common sugars like sucrose (table sugar), its chemical formula is **C₁₂H₂₂O₁₁**. This means it contains 12 carbon atoms, 22 hydrogen atoms, and 11 oxygen atoms.
