WebPhotosynthesis is important because it provides two main things: food. oxygen. Some of the glucose that plants produce during photosynthesis is stored in fruits and roots. This is why we are able to eat carrots, potatoes, apples, water melons and all the others. These foods provide energy for humans and animals. WebJan 25, 2024 · Know Everything About Photosynthesis Here. In the electron transport chain, a group of proteins carry electrons through a membrane within the thylakoid to build a proton gradient that drives the synthesis of adenosine triphosphate \ (\left ( { {\rm {ATP}}} \right)\). The cell uses \ ( {\rm {ATP}}\) as an energy source for metabolic processes ...
