Question

Photosynthesis occurs when chlorophyll absorbs sunlight causing a chemical reaction to occur in the

Answer 1

chloroplasts of plants. This reaction involves the conversion of carbon dioxide and water into glucose and oxygen. The process can be summarized by the following equation:

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

In the presence of light, chlorophyll molecules capture photons and use their energy to split water molecules into hydrogen ions (H+) and oxygen. This process is known as photolysis of water. The released oxygen is then released into the atmosphere as a byproduct.

The hydrogen ions, along with the electrons from the chlorophyll, are used to convert carbon dioxide into glucose through a series of chemical reactions in a process called the Calvin Cycle. Glucose produced during photosynthesis is then used for various metabolic processes in the plant, including growth, storage, and energy production.

Overall, photosynthesis is a vital process for plants as it allows them to convert sunlight into chemical energy, which they can use for growth and survival. Additionally, the oxygen released during photosynthesis is essential for maintaining atmospheric oxygen levels, supporting other organisms, and balancing the earth's carbon cycle.
