Verified step by step guidance

Understand the categories of carbon-based molecules: Proteins, Lipids, Nucleic Acids, and Carbohydrates. Each category has distinct structures and functions in biological systems.

Recall that carbohydrates are composed of carbon (C), hydrogen (H), and oxygen (O) atoms, typically in a ratio of 1:2:1. Their primary function is to provide energy and structural support.

Recognize that sugars (e.g., glucose, fructose) are simple carbohydrates, also known as monosaccharides or disaccharides, which serve as quick energy sources.

Identify starches as complex carbohydrates, also known as polysaccharides, which are long chains of glucose molecules used for energy storage in plants.

Conclude that sugars and starches are both part of the carbohydrate category because they share the same fundamental chemical composition and biological roles.
