Study Notes

Nutrition: Types of Organisms, Nutrient Requirements and Food Processing

Nutrient refers to any substance required for growth and maintenance of an organism.
Autotrophs obtain energy from sunlight and chemicals to produce their food, while heterotrophs cannot make their food and obtain energy from other organisms.
Plants require water and carbon dioxide for photosynthesis, which converts sunlight into chemical energy.
Essential nutrients include macronutrients and micronutrients required in amounts above 0.5% and trace amounts, respectively.
Macronutrients include C, H, O, N, K, Ca, Mg, P, S, while micronutrients include Cl, Fe, B, Mn, Zn, Co, Mo.
Water and minerals from soil are absorbed through the symplast and apoplast routes and reach the xylem.
Calorie is a unit of energy that indicates the amount of energy contained in food.
Carbohydrates, proteins, and fats serve as major energy sources and building materials for cell structures and enzymes.
Carbohydrates and proteins contain 4 Calories per gram, while fats contain about 9 Calories per gram.
Essential nutrients for animals include amino acids, fatty acids, and vitamins, which cannot be synthesized inside the body.
Main stages of food processing include ingestion, digestion, absorption, and elimination.
Chemical digestion by enzymes involves breaking chemical bonds through the addition of water, i.e., enzymatic hydrolysis.
