  Small Molecular Weight Organic Compounds in Living Tissues (NEET Biology Notes) Biomolecules in Living Tissues: Complete NEET study chart covering carbohydrates, amino acids, lipids, nucleotides, DNA and RNA. Chapter: Biomolecules -Dr.Sanjaykumar Pawar  Introduction Living organisms are made up of different types of organic molecules . These molecules are called biomolecules because they are essential for life. The four major groups of biomolecules are: Carbohydrates (Sugars) Proteins (Amino acids) Lipids (Fats and Oils) Nucleic Acids (DNA & RNA building blocks) These molecules perform different functions such as providing energy, building body tissues, storing food, and carrying genetic information. 1. Carbohydrates (Sugars) What are carbohydrates? Carbohydrates are the main source of energy in living organisms. They are made up of three elements: Carbon (C) Hydrogen (H) Oxygen (O) General formula: (CH₂O)ₙ Examples shown in the figure (A) Glucose Molecular Formula: C₆...

  Chapter 19: Chemical Coordination and Integration — Introduction to Endocrine Glands and Hormones for Class 11 Biology NEET Preparation Chapter 19: Chemical Coordination and Integration Easy NEET Biology Notes (Line-by-Line Explanation) By- Dr.Sanjaykumar Pawar  Introduction Original Idea: The nervous system provides rapid coordination among organs. Easy Explanation: Our body organs must work together properly. The nervous system controls body activities quickly using nerve impulses . Example: Touching a hot object → hand withdraws immediately. Original Idea: Neural coordination is fast but short-lived. Easy Explanation: Nervous signals act very fast. But their effect lasts for a short time only. Example: Muscle contraction after a nerve impulse stops quickly. Original Idea: Nerve fibres do not innervate all cells. Easy Explanation: Nerves cannot reach every cell of the body directly. Some body functions need continuous regulation. Origin...
