What is the difference between oxygenic and Anoxygenic photosynthetic bacteria?
Because oxygen is generated as a byproduct and is released, this type of photosynthesis is referred to as oxygenic photosynthesis. However, when other reduced compounds serve as the electron donor, oxygen is not generated; these types of photosynthesis are called anoxygenic photosynthesis.
What is the difference between cyanobacteria and photosynthetic bacteria?
The main difference between bacteria and cyanobacteria is that the bacteria are mainly heterotrophs while the cyanobacteria are autotrophs. Furthermore, bacteria do not contain chlorophyll while cyanobacteria contain chlorophyll-a.
What are the different photosynthetic apparatus of a given plant and photosynthetic bacteria?
The main difference between bacterial and plant photosynthesis is the difference in the electron donor. In bacterial system, H2S or thiosulfate mostly acts as an electron donor, and in the plant system, H2O acts as an electron donor, so oxygen is produced in plant photosynthesis but not in bacterial photosynthesis.
Why is bacterial photosynthesis called Anoxygenic?
Anoxygenic photosynthesis is the phototrophic process where light energy is captured and converted to ATP, without the production of oxygen; water is, therefore, not used as an electron donor.
How are oxygenic and anoxygenic photosynthesis similar?
Similarities Between Oxygenic and Anoxygenic Photosynthesis Oxygenic and anoxygenic photosynthesis are two types of photosynthesis. Photoautotrophs undergo both oxygenic and anoxygenic photosynthesis. Both oxygenic and anoxygenic photosynthesis occurs in two steps: light dependent reaction and dark reaction.
How are Anoxygenic Phototrophic microorganisms more physiologically diverse than oxygenic phototrophic microorganisms?
Anoxygenic phototrophs are more physiologically/metabolically diverse than oxygenic phototrophs due to the difference of soluble electron donors under anoxic conditions. Such as sulfides, ferrous (Fe2+), and nitrates which are often utilized by anoxygenic phototrophs.
What are some structural differences between bacteria and cyanobacteria?
| Bacteria vs Cyanobacteria | |
|---|---|
| Bacteria are a prokaryotic organism possessing a simple unicellular structure. | Cyanobacteria are a group of bacteria possessing chlorophyll a, making them able to photosynthesize. |
| Size | |
| Bacteria are comparatively smaller than cyanobacteria. | Cyanobacteria are comparatively larger than bacteria. |
Which of the following is an Anoxygenic photosynthetic organism?
Several groups of bacteria can conduct anoxygenic photosynthesis: green sulfur bacteria (GSB), red and green filamentous phototrophs (FAPs e.g. Chloroflexi), purple bacteria, acidobacteria, and heliobacteria.
What is bacterial photosynthetic apparatus?
Bacteriochlorophyll a is the most widely distributed type of chlorophyll recognized in photosynthetic bacteria. Chromatophores represent a specialized structure that essentially houses the photosynthetic pigments and catalyzes photophosphorylation and photoreduction reactions.
What are the photosynthetic bacteria?
Within the prokaryotic domain, there are five main groups of bacteria that perform tetrapyrrole-based photosynthesis. They are proteobacteria (also known as purple bacteria), heliobacteria, Chloroflexi (filamentous bacteria also known as green non-sulfur bacteria), Chlorobi (green sulfur bacteria) and cyanobacteria.
Which is an Anoxygenic photosynthetic organism?
What does anoxygenic photosynthesis involve?
Anoxygenic photosynthesis is the phototrophic process where light energy is captured and converted to ATP, without the production of oxygen. Water is therefore not used as an electron donor.
