Lecture Notes on Nutrition and Biological Processes

Key Topics Covered

Nutrients and Their Importance

  • Parasitic Nutrients: Significance in biological systems.
  • Carbohydrates:
    • Primary type is glucose
    • Molecular Formula: C6H12O6

Photosynthesis

  • Conversion of carbon dioxide and water into glucose, releasing oxygen.
  • Energy transformation: Photosynthesis converts light energy into chemical energy.

Digestion and Absorption

  • Undigested Material: Involves pancreatic and salivary glands.
    • Salivary Glands: Produce salivary amylase which aids in the digestion of carbohydrates.
    • Pancreatic Juice: Contains enzymes that further digest nutrients.

Energy Release

  • Different processes release varying amounts of energy

Hormonal Regulation

  • Role of hormones in body functions.

Blood Components

  • Platelets: Important in blood clotting and repair processes.
  • Oxygenated Blood: Vital for transporting oxygen throughout the body.

Kidney Structure and Function

  • The pair of kidneys are crucial for filtering blood and maintaining homeostasis.
  • Basic Functional Units: Nephrons are the structural and functional units of kidneys.
