What are the organic substances produced by photosynthesis? What are the material changes in photosynthesis?

Photosynthesis is the process by which producers such as plants, algae, and some bacteria use light energy to convert carbon dioxide, water, or hydrogen sulfide into carbohydrates. Photosynthesis is the sum of a series of complex metabolic reactions. It is the basis for the survival of the biological world and an important medium for the earth's carbon-oxygen cycle. What are the material changes in photosynthesis? What are the organic substances produced by photosynthesis? Let's explore and talk about it together.

What organic matter is produced by photosynthesis?

Photosynthesis, or light energy synthesis, is a biochemical process in which plants, algae and some bacteria use their cells to convert carbon dioxide and water into organic matter and release oxygen through light and dark reactions under the irradiation of visible light, using photosynthetic pigments. Photosynthesis is the sum of a series of complex metabolic reactions. It is the basis for the survival of the biological world and an important medium for the earth's carbon-oxygen cycle. Plants are called producers in the food chain because they can use inorganic matter to produce organic matter and store energy through photosynthesis.

What are the changes in matter during photosynthesis?

The material changes during photosynthesis are: carbon dioxide and water are converted into organic matter, while oxygen is released.

Water decomposes in the light reaction phase to release oxygen, while generating ATP and reduced hydrogen. Carbon dioxide first combines with five-carbon compounds in the dark reaction phase to generate three-carbon compounds, which are then reduced to organic matter, while five-carbon compounds and water are generated.

Photosynthesis is the process by which producers such as plants, algae and some bacteria use light energy to convert carbon dioxide, water or hydrogen sulfide into carbohydrates. Photosynthesis can be divided into oxygenic photosynthesis and non-oxygenous photosynthesis.

Is starch the only organic matter produced by photosynthesis?

The essence of photosynthesis is the process by which green plants use light energy through chloroplasts to convert carbon dioxide and water into organic matter (such as starch) that stores energy and releases oxygen. It can be summarized in two aspects: on the one hand, simple inorganic matter is converted into complex organic matter and oxygen is released, which is the material conversion process; on the other hand, while inorganic matter is converted into organic matter, light energy is converted into chemical energy stored in the organic matter, which is the energy conversion process.
