What is the purpose of chlorophyll and bacteriochlorophyll molecules?

What is the purpose of chlorophyll and bacteriochlorophyll molecules?

They are related to chlorophylls, which are the primary pigments in plants, algae, and cyanobacteria. Organisms that contain bacteriochlorophyll conduct photosynthesis to sustain their energy requirements, but do not produce oxygen as a byproduct. They use wavelengths of light not absorbed by plants or Cyanobacteria.

Why do different Phototrophs have different forms of chlorophyll or bacteriochlorophyll that absorb light of different wavelengths?

These types of chlorophyll and bacteriochlorophyll differ in structure, and those differences affect the specific wavelength of light that each can absorb, which allows several different species of microbes together to collect the full spectrum of light, each absorbing a different range of wavelengths.

What is the purpose of chlorophyll and bacteriochlorophyll molecules in what ways do they resemble cytochromes and in what ways to they differ?

In what ways do they resemble cytochromes and in what ways do they differ? Chlorophyll and bacteriochlorophyll absorb light used in order to convert into energy, usually ADP to ATP. Both chlorophylls and cytochromes are found on photosynthetic membranes of the mitochondria.

Do cyanobacteria have bacteriochlorophyll?

Cyanobacteria contain chlorophyll while other forms of bacteria contain bacteriochlorophyll. Although bacteriochlorophyll resembles chlorophyll, it absorbs light of a longer wavelength than chlorophyll. Bacteriochlorophyll a is the most common form of bacteriochlorophyll but other forms include b, c, d, e, f and g.

Are bacteriochlorophyll and Bacterioviridin same?

These are not same but are related. Bacteria possess two types of related pigments— bacteriochlorophyll and bacterioviridin (= chlorobium chlorophyll).

Where is bacteriochlorophyll found?

Bacteriochlorophyll is located in specialized membrane systems (chromatophores); in purple bacteria these are in the form of sheets, tubes, or vesicles arising inside the cell from the plasma membrane, whereas in green bacteria they are cylindrical structures ( chlorosomes) underlying the plasma membrane.

Do cyanobacteria have chlorophyll?

Cyanobacteria may be unicellular or filamentous. Cyanobacteria contain only one form of chlorophyll, chlorophyll a, a green pigment. In addition, they contain various yellowish carotenoids, the blue pigment phycobilin, and, in some species, the red pigment phycoerythrin.
