LIFE PROCESSES SSLC kseeb science chapter

Life process is a SSLC science chapter which will be helpful to study

1. LIFE PROCESSES An Overview of Essential Functions in Living Organisms An Overview of Essential Functions in Living Organisms

2. What are life processes? Life processes are the essential functions that organisms perform to maintain life .

3. life processes Nutrition 2.Respiration 3.Transportation 4.Excretion

4. 1.Nutrition Definition: The process of obtaining and utilizing food. Types: Autotrophic (e.g., plants) – Organisms that make their own food using sunlight (photosynthesis). Heterotrophic (e.g., animals) – Organisms that depend on other organisms for food . Importance : Provides energy and essential nutrients .

10. 2. Respiration Definition : The process by which cells release energy from food. Respiration is the breakdown of food (glucose) to release energy

11. Types: Aerobic Respiration (human, cats, dogs, etc.): Uses oxygen and produces more energy. Anaerobic Respiration (Alcohol fermentation, decomposition of organic matter, etc.) : Occurs without oxygen, producing less energy Importance: Provides energy for cellular activities.

12. Catabolism:  Definition: Catabolism is the metabolic pathway that breaks down complex molecules into simpler ones.  Energy: It releases energy in the process, often stored as ATP (adenosine triphosphate).  Examples:   Breaking down food molecules (carbohydrates, proteins, fats) into smaller units for energy.  Glycogenolysis (breaking down glycogen into glucose).  Lipolysis (breaking down fats into fatty acids).  Purpose: To provide energy for cellular processes and to produce building blocks for anabolism. 

13. Anabolism:  Definition: Anabolism is the metabolic pathway that constructs complex molecules from simpler ones.  Energy: It requires energy to build these complex molecules.  Examples: Protein synthesis (building proteins from amino acids).  Glycogenesis (building glycogen from glucose).  Lipogenesis (building fats from fatty acids).  Purpose: To build and maintain cellular structures, store energy, and support growth and repair. 

14. Definition : the process of breaking down of organic matters to release stored potential energy

15. Definition : the process of moving air into (inhalation) and out (Exhalation) of the lungs to facilitate gas exchange, bringing in oxygen and removing carbon dioxide

16. 3. Transportation Definition: The movement of materials within the organism. Example in Humans : The circulatory system moves oxygen. Example in Plants : Water and nutrients are transported through the stem and leaves.

17. Transportation of blood in human (circulation)

18. Carries blood away from the heart to tissues of the body. Found deeper within the body Carries blood from tissues of the body to the heart. Usually found closer beneath skin.
