  Congratulations to Preethi from II B.Sc Biochemistry for Winning 2nd Prize in Speech Competition!              We are delighted to share that Preethi from II B.Sc Biochemistry, Marudhar Kesari Jain College for Women (Autonomous) has secured the Second Prize in the speech competition held 22.11.2025 at Gandhinagar School, Vaniyambadi . Her confident delivery, clarity of thought, and impressive stage presence earned her well-deserved appreciation from the judges and the audience. As a recognition of her achievement, she received a cash prize of ₹750 . This accomplishment reflects her dedication, hard work, and passion for effective communication. The department proudly celebrates her success and encourages more students to participate in such enriching events. Congratulations once again, Preethi. May this achievement inspire many more milestones ahead.

  Biochemistry in Day-to-Day Life Biochemistry is not just a laboratory science — it is the chemistry of your everyday life . Every breath you take, every emotion you feel, every food you eat, and every medicine you swallow works because of biochemical reactions inside the body. Below are the most common, relatable everyday examples: 1. Breathing & Energy: The Biochemistry of Life When you breathe in oxygen, your cells use it to break down glucose (from food). This process, called cellular respiration , produces ATP , the energy currency of the body. Without ATP, you cannot walk, think, study, or even blink. 👉 Every breath = a biochemical reaction that keeps you alive. 2. Digestion: How Your Body Breaks Down Food Your saliva contains enzymes like amylase that start digesting carbohydrates the moment you eat. In the stomach, pepsin digests proteins. In the intestine, lipase digests fats. 👉 What you eat becomes usable nutri...

  Biochemistry of Allergy and the Impact on Health Allergies are exaggerated immune responses to normally harmless substances (allergens). The biochemical pathways underlying allergies involve immune sensitization , IgE production , mast cell activation , and inflammatory mediator release . These reactions can range from mild symptoms to life-threatening anaphylaxis. Understanding the biochemical basis helps in better diagnosis, prevention, and therapeutic intervention. 1. What Is an Allergy?  An allergy is a hypersensitivity reaction mediated predominantly by Immunoglobulin E (IgE) . When allergens such as pollen, dust mites, foods, or drugs enter the body, immune cells mistakenly identify them as threats and activate pathways involving: B cells T helper 2 (Th2) cells IgE antibodies Mast cells & basophils Histamine and other mediators 2. Sensitization Phase: How the Body First Develops an Allergy Step-by-step Biochemical Events Allergen Entry: ...

  Biochemistry of Diabetes & Why It’s Increasing in India Diabetes mellitus is one of the most significant metabolic disorders affecting India today. At its core, diabetes is a condition of impaired glucose homeostasis , resulting either from insufficient insulin production or reduced tissue response to insulin. Understanding the biochemical basis of diabetes helps explain both how the disease develops and why its prevalence is rising rapidly in India. I. Biochemistry of Diabetes 1. Role of Insulin in Glucose Homeostasis Insulin, produced by the β-cells of the pancreas , is central to regulating blood glucose levels. Its major biochemical actions: In the liver Decreases gluconeogenesis Promotes glycogen synthesis Inhibits glycogen breakdown In muscle Facilitates glucose uptake via GLUT-4 transporters Enhances glycogen formation and protein synthesis In adipose tissue Stimulates lipogenesis Inhibits hormone-sensitive lipase, reduci...
