Macronutrients: Carbohydrates, Fats & Proteins

Macronutrients provide the energy and building blocks required for every major biological process in the human body. This comprehensive High School Biology instructional unit helps students understand how carbohydrates, fats, and proteins contribute to metabolism, growth, cellular function, physical performance, and overall health.

Designed for Grades 10–12, this resource integrates Biology, Human Physiology, Nutrition, and Health Science through inquiry-based learning, scientific investigations, and authentic real-world applications. Students develop a deep understanding of nutrition while strengthening analytical thinking and scientific literacy.

Product Description

Students first investigate carbohydrates as the body's primary short-term energy source. They explore monosaccharides, disaccharides, polysaccharides, the glycemic index, blood glucose regulation, insulin, and sports nutrition.

The second section focuses on lipids, examining triglycerides, saturated and unsaturated fatty acids, cholesterol, omega-3 and omega-6 fatty acids, cardiovascular health, and healthy dietary patterns.

Students then investigate proteins, amino acids, protein synthesis, enzymes, muscle development, complete and incomplete proteins, and the biological importance of dietary protein.

The final lessons integrate all three macronutrients into a broader understanding of energy balance, metabolism, healthy eating, nutrition planning, and lifestyle choices. Through authentic case studies and scientific investigations, students connect nutrition science with human physiology and everyday health.
