What Is Photosynthesis? From Light Energy to Chemical …

How does the energy get to the reaction center? It happens through a process of radiationless energy transfer. Once it absorbs the right amount of energy, the reaction centre will initiate an electron transport chain, much like the one that operated in oxidative phosphorylation. A photon doesn't need to strike the reaction centre itself, however, because it can strike any of the surrounding chromophores in the light harvesting complex. These molecules are all in close contact with each other, so it is relatively easy for molecules to collide and to transfer that entire amount of energy from one molecule to the next. During that transfer, the first molecule relaxes back to the ground state and the next molecule is excited into the excited state.

Photosynthesis occurs through light reactions (chemiosmosis) and dark reactions (the Calvin cycle).

Photosynthesis The equation for photosynthesis is CO2 + H2O +energy = C6H12O6 + O2 Photosynthesis is the process of taking in the sun's energy and converting it into chemical energy to be stored away in the form of glucose.

We'll get back to the oxygen-evolving complex in a later unit. Right now let's figure out what all those other molecules are doing in that scrum at the top of the picture, and why they are important. This is the light harvesting complex. Its job is to collect energy from sunlight and convert that energy into forms that the plant can use. Of course, somewhere along the line you learned in biology class that chlorophyll is what makes photosynthesis possible, and there are several chlorophyll molecules in the light harvesting complex. There are many different members of this family of molecules in nature, found in different organisms that can survive on sunlight: plants, algae, some plankton, a few bacteria. The chlorophylls commonly found in plants are chlorophyll a and chlorophyll b, shown below.

Photosynthesis Similarities Differences The Relationship Between the Processes Works Cited There are a number of similarities between these two series of reactions such as their equations, transformation of energy, exchange of gases, the Eletron Transport Chain and Chemiosmosis, and the theory of endosymbiosis.

A food chain always starts with a producer, which is an organism that makes food. This is usually a green plant, because plants can make their own food by photosynthesis.
