the cell. During this process‚ water molecules are broken down into oxygen and hydrogen atoms which are then released in the air. In the very early days of life‚ Earth was populated only by anaerobic bacteria that didn’t need oxygen to survive. When cyanobacteria first made their appearance and started engaging in their photosynthetic reactions‚ large amounts of oxygen were suddenly released in the atmosphere. This lead to what is known as the Great Oxygenation Event‚ which took place around 2.5
