Answer 1

При его участии происходит фотосинтез. Главная функция хлорофилла - поглощение света, превращение световой энергии в электронную, передача её клеткам.

Answer 2

The Importance of Chlorophyll in Photosynthesis

Chlorophyll is a key molecule in photosynthesis, the process by which plants and other organisms convert light energy into chemical energy. It plays a crucial role in capturing and harnessing light energy from the sun, which is then used to produce glucose and oxygen.

Chlorophyll absorbs light energy: Chlorophyll molecules are located in the chloroplasts of plant cells and are responsible for absorbing light energy. They are specifically designed to absorb light in the blue and red regions of the electromagnetic spectrum, while reflecting or transmitting green light. This is why plants appear green to our eyes.

Chlorophyll initiates the electron transport chain: Once chlorophyll molecules absorb light energy, they transfer it to other molecules in a process called the electron transport chain. This chain of reactions ultimately leads to the production of ATP (adenosine triphosphate), the energy currency of cells, and NADPH (nicotinamide adenine dinucleotide phosphate), a molecule used in the synthesis of glucose.

Chlorophyll is involved in the synthesis of glucose: The energy captured by chlorophyll is used to power the synthesis of glucose through a series of chemical reactions known as the Calvin cycle. Glucose is a vital source of energy for plants and serves as a building block for the production of other organic compounds necessary for growth and development.

Chlorophyll releases oxygen: As a byproduct of photosynthesis, chlorophyll releases oxygen into the atmosphere. This oxygen is essential for the survival of many organisms, including humans, as it is used in cellular respiration to produce energy.

In summary, chlorophyll is a key molecule in photosynthesis because it absorbs light energy, initiates the electron transport chain, is involved in the synthesis of glucose, and releases oxygen as a byproduct. Without chlorophyll, the process of photosynthesis would not be possible, and life on Earth as we know it would be drastically different.
