Plants are the dominant photosynthetic autotrophs on the Earth.

Note the column in the table above which lists electron donors used for (photo)autotrophic growth by the various groups of organisms. For those organisms which can grow as heterotrophs – such as the purple non-sulfur photosynthetic bacteria – we would expect that various organic compounds could serve as electron donors. New editions of Bergey's Manual and modern textbooks (such as Brock) can be consulted for further information. There is more about energy generation and reducing power .

which occurs in photosynthetic bacteria.

The purple bacteria are good examples to illustrate many of the features.Recall that

It appears to stimulate the photosynthesis of host bacteria.

Method to Transport Synthesized Glucose
to the Rest of the Body Two Photosynthetic Pathways However, in the anoxygenic pathways of photosynthesis, water is not the reducing agent, meaning oxygen is not formed.

The basic equation of photosynthesis is deceptively simple.

Small body size of Elysia slug does not require complex system for transport of synthesized glucose from the membrane to the rest of the body.
Have the ability to fold wing-like structures on to of its back or unroll them to increase area available to absorb light for photosynthesis.

These folds contain 3 types of molecular complexes involved in photosynthesis:1) Antenna or

Photosynthesis in Other Anoxygenic Photosynthetic Bacteria

One must appreciate the fact that the purple non-sulfur bacteria would probably be overrun (crowded out) by various respiring chemotrophs from the sample if our enrichments and plates were incubated under aerobic conditions. Aerobically, the photosynthetic pigments would not be as visible (if at all), and picking likely colonies of these organisms would be difficult or impossible. Likewise, they would probably be overrun by fermenting chemotrophs if our enrichments and plates were incubated under anaerobic conditions with a "popular" carbon source such as glucose in the medium.

Pigments in Photosynthetic Bacteria

THE ABOVE RIGHT PHOTO shows a plate streaked from an enrichment and then incubated anaerobically in the light. Note the pigmented colonies of purple non-sulfur photosynthetic bacteria.

Rhodopseudomonas acidophila Purpose of Light Harvesting Complexes: LH1 The light harvesting complex 1 is used as the primary light harvesting proteins or the antenna system for absorption in the bacteria.
The complexes are able to collect more light than the photosynthetic reaction center would be able to alone.
Energy from LH1 is transferred to the reaction center to begin electron transport .
Eventually this drives ATP to convert solar energy to chemical energy in the bacterial cell.
These light harvesting complexes are apart of a larger photo system function unit that plants and photosynthetic bacteria contain.

In photosynthesis, solar energy is converted to chemical energy.

The inner membrane is
extensively folded into sacs, tubes or sheets, increasing its surface area, and most of the photosynthetic machinery is
located on these folds.

History of Photosynthetic Bacteria 2

Introduction to Photosynthetic Bacteria Photosynthesis was first utilized by bacteria.
Early in Earth's history, these organisms filled the atmosphere with oxygen which allowed life to evolve aerobic pathways to create energy.
It is believed that plants obtained their chloroplasts and the ability of photosynthesis through the capture of bacterial cells.

What would it look like for marathon runners to have photosynthetic cells to utilize sunlight for energy during a run?
Could photosynthetic cells keep a lost backpacker alive after his food supply is depleted?
Could we use these cells as a way to give underdeveloped countries a source of energy daily?
