Question

Каковы этапы обмена веществ ? ​

Answer 1

Объяснение:

Метаболизм обычно делят на 2 стадии: катаболизм и анаболизм. В ходе катаболизма сложные органические вещества деградируют до более простых, обычно выделяя энергию, а в процессах анаболизма — более сложные вещества синтезируются из более простых с затратами энергии.

Answer 2

Metabolism Stages

Metabolism is the process by which the body converts food and drink into energy. It involves several stages:

1. Anabolism: This is the process of building complex molecules from simpler ones. It requires energy and is responsible for the growth and repair of cells. An example of an anabolic reaction is the synthesis of protein from amino acids.

2. Catabolism: Catabolism is the breakdown of complex molecules into simpler ones, releasing energy in the process. For example, the breakdown of glucose to produce energy is a catabolic process.

3. Digestion: This stage involves the breakdown of food into smaller components that can be absorbed and used by the body. It occurs in the digestive system and involves the action of enzymes to break down carbohydrates, proteins, and fats.

4. Absorption: Once food is broken down in the digestive system, the nutrients are absorbed into the bloodstream to be transported to cells throughout the body. This stage primarily occurs in the small intestine.

5. Transport: After absorption, nutrients are transported via the bloodstream to various tissues and organs where they are needed for energy production, growth, and repair.

6. ATP Production: Adenosine triphosphate (ATP) is the energy currency of the cell. During metabolism, energy from nutrients is used to produce ATP, which is then utilized by the body for various cellular processes.

These stages collectively make up the process of metabolism, which is essential for the functioning and maintenance of the body.
