Photosynthesis and Respiration: The Big Picture …

What next? All of that captured light energy needs to be converted into a different form; that's the whole point of photosynthesis. We aren't quite ready for that, though. The light harvesting complex just collects the light; the nearby reaction center is where the conversion process begins. You can think of the light harvesting complex as an antenna or as a funnel that sends energy to the reaction center, where the process of converting the energy into ATP (and, later, carbohydrates) will begin.

One of the areas of study Karplus chose to pursue after his stay in Israel was the role of retinal in vision. Retinal is related to the carotenoids, for basically half a carotenoid molecule is vitamin A, and when oxidized vitamin A becomes retinal. Retinal also is one example of a polyene, a type of chemical compound with multiple carbon-carbon bonds. Polyenes play key roles in light absorption in vision as well as in photosynthesis. Studying polyenes would become a major focus of the Karplus group at Harvard.

The complex process of photosynthesis actually consists of TWO interrelated complex reactions -- the LIGHT and DARK reactions.

Electron transfer processes were known to be involved in photosynthesis. Being in an electron transfer group, Schulten says that in the back of everybody's minds was an awareness of just how important electron transfer was to photosynthesis. So in 1978 Schulten and Werner, along with their director, Albert Weller, published a paper suggesting that the new effect could be used as a ruler to characterize in more detail the electron transfer that occurs in photosynthesis. The goal was to use the magnetic field effect to understand better the electron transfer in photosynthesis.

The effect is to harvest light from a slightly broader range of the visible spectrum. That makes for a more efficient process. Because sunlight contains wavelengths that range all across the visible spectrum (and beyond), the more of these wavelengths that can be captured, the more efficient photosynthesis can be.

There were many reasons why Schulten already knew enough about electron transfer in photosynthesis to suggest using the magnetic field effect as a yardstick in his 1978 paper. The electron transfer in photosynthesis occurred in a protein called the photosynthetic reaction center, which may be thought of as the heart of the photosynthetic unit. When plants and bacteria absorb energy from the sun, this energy is used by the reaction center to transfer an electron. The workings of the reaction center were not fully understood because the structure of this protein was not known in the late 1970s when Schulten was in Göttingen. “So people actually did very well,” recalls Schulten, “to conclude, from certain optical properties and from electron transfer rates, what the structure looked like. So it was amazingly good actually, but it was not firm.”

What is the purpose of photosynthesis

Why is it important?
one product of photosynthesis is glucose, which provides the basis for most food chains.
The second product of photosynthesis is oxygen which comes in handy if you happen to be an organism that requires oxygen for survival.
