During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by ...
However, the evolution of photosynthesis goes back even further, to the earliest cells that evolved the ability to capture light energy and use it to produce energy-rich molecules. When these ...
Be careful not to confuse this photosynthesis equation with respiration which is the reverse of this. The balanced symbol equation shown above is Higher tier only.
Enzymes are also involved in the building up of chemical molecules elsewhere in the body. In an organism, the active site of each enzyme is a different shape. It is a perfect match to the shape of ...
