Study Notes
Life Processes in Living Organisms: 9th Class
Respiration
Respiration is a fundamental metabolic process that involves the exchange of gases between an organism and its environment. It consists of two main components: cellular respiration and external respiration.
Cellular respiration is the process by which cells produce energy in the form of ATP (adenosine triphosphate) from the food they consume. This process occurs in the mitochondria of cells and involves several stages: glycolysis, the Krebs cycle, and the electron transport chain. Glycolysis is the breakdown of glucose into pyruvate, generating a small amount of ATP and NADH. The Krebs cycle, also known as the citric acid cycle, takes place in the mitochondrial matrix and produces more ATP, NADH, and FADH2. The electron transport chain occurs in the inner mitochondrial membrane and generates the majority of ATP through oxidative phosphorylation.
External respiration is the process by which cells obtain oxygen and release carbon dioxide. In vertebrates, this process takes place in the lungs, while in insects and other invertebrates, it occurs in the book lungs or trachea. Oxygen enters the bloodstream and is transported to cells via hemoglobin, while carbon dioxide is expelled from the body.
Transportation
Transportation is the process by which substances are moved from one part of an organism to another. This crucial life process is essential for maintaining homeostasis and supporting various functions within the organism.
Amino acid transport is the movement of amino acids across the cell membrane. This process is facilitated by specific carrier proteins that can bind to amino acids and transport them across the membrane. In some cases, the transport process can be passive, while in others, it requires the input of energy in the form of ATP.
Endocytosis and exocytosis are two types of cellular transport processes that involve the movement of substances into and out of cells. Endocytosis is the process by which cells engulf external substances, while exocytosis is the opposite, where cells release substances into the extracellular environment. Both of these processes play a crucial role in maintaining the balance of substances within cells and the organism as a whole.
Excretion
Excretion is the process by which waste products are removed from an organism. This process is essential for maintaining homeostasis and preventing the buildup of harmful substances within the body.
In humans and other mammals, the primary excretory organs are the kidneys, which play a crucial role in maintaining water and electrolyte balance. The kidneys filter waste products, such as urea and uric acid, from the blood and excrete them in the form of urine. Other excretory organs in humans include the liver, which produces bile for the digestive system, and the lungs, which expel carbon dioxide during respiration.
In plants, the primary excretory organ is the root system, which releases excess water and minerals through a process called osmosis. This process helps maintain water balance within the plant and ensures that nutrients are not depleted.
In summary, life processes, such as respiration, transportation, and excretion, are essential for maintaining the overall health and balance of living organisms. Understanding these processes can provide valuable insights into the fundamental workings of life and the mechanisms that sustain it.
