Кислород роль газа помогите ребят плиз

Answer 1

Живые существа дышат кислородом воздуха. Широко используется кислород в медицине. При сердечно-сосудистых заболеваниях, для улучшения обменных процессов, в желудок вводят кислородную пену(«кислородный коктейль»). Подкожное введение кислорода используют при трофических язвах, слоновости,гангрене и других серьезных заболеваниях. Для обеззараживания и дезодорации воздуха и очистки питьевойводы применяют искусственное обогащение озоном. Радиоактивный изотоп кислорода 15O применяется дляисследований скорости кровотока, лёгочной вентиляции.

The Role of Oxygen Gas

Oxygen gas plays a crucial role in various aspects of life on Earth. It is essential for the survival of most living organisms, including humans. Here are some key points about the role of oxygen gas:

1. Cellular Respiration: Oxygen is necessary for the process of cellular respiration, which occurs in the mitochondria of cells. During cellular respiration, glucose and oxygen react to produce carbon dioxide, water, and energy in the form of ATP (adenosine triphosphate). This energy is used by cells to carry out their functions and sustain life.

2. Aerobic Organisms: Oxygen is required by aerobic organisms, which include most plants and animals, to carry out aerobic respiration. Aerobic respiration is a more efficient process of energy production compared to anaerobic respiration, which does not require oxygen. In the presence of oxygen, organisms can generate more ATP, allowing them to perform more complex functions.

3. Metabolism: Oxygen is involved in the metabolic processes of organisms. It is used in the breakdown of nutrients, such as carbohydrates, fats, and proteins, to release energy. This energy is then utilized for various physiological functions, including growth, repair, and reproduction.

4. Oxygen Transport: In multicellular organisms, oxygen is transported throughout the body via the circulatory system. In humans, oxygen is bound to hemoglobin molecules in red blood cells and carried to tissues and organs. This ensures that oxygen reaches all cells in the body, providing them with the necessary oxygen for respiration.

5. Combustion and Oxidation Reactions: Oxygen is highly reactive and supports combustion and oxidation reactions. It is often used as an oxidizing agent in various industrial processes, such as metal smelting, fuel combustion, and chemical synthesis.

6. Ozone Layer: Oxygen gas (O2) also plays a crucial role in the Earth's atmosphere. It is responsible for the formation of the ozone layer (O3), which protects life on Earth by absorbing harmful ultraviolet (UV) radiation from the Sun.

These are just a few examples of the important role that oxygen gas plays in various biological and chemical processes. Its presence is vital for sustaining life and supporting numerous essential functions.
