Question

В листьях берёзы из углекислого газа и воды на свету образуется крахмал укажи название процесса

Answer 1

Фотосинтез, тк при фотосинтезе растение поглощает углекислый газ и воду и образует глюкозу крахмал и кислород

Answer 2

Process of Starch Formation in Birch Leaves

In the process of photosynthesis, starch is formed in the leaves of birch trees. This process involves the conversion of carbon dioxide (CO2) and water (H2O) into glucose, which is then polymerized to form starch. The specific process responsible for starch formation in plants is known as starch synthesis or starch biosynthesis.

During photosynthesis, plants use sunlight as an energy source to convert CO2 and H2O into glucose. This process occurs in the chloroplasts of plant cells, specifically in the chlorophyll-containing cells of the leaves. The energy from sunlight is captured by chlorophyll, which initiates a series of chemical reactions.

The overall equation for photosynthesis is as follows:

6 CO2 + 6 H2O + light energy → C6H12O6 (glucose) + 6 O2

Glucose is then converted into starch through a process called starch synthesis. This process involves the polymerization of glucose molecules to form long chains of starch. Starch serves as a storage form of glucose in plants and is stored in specialized structures such as amyloplasts.

The process of starch synthesis in plants is regulated by various enzymes, including starch synthase and starch branching enzyme. These enzymes catalyze the formation of starch by linking glucose molecules together and creating the branched structure characteristic of starch.

In summary, the process of starch formation in birch leaves involves the conversion of CO2 and H2O into glucose through photosynthesis. Glucose is then polymerized to form starch through the process of starch synthesis. This process is regulated by specific enzymes and occurs in the chloroplasts of plant cells.
