MBY 251 Theme 4- Metabolic Diversity of
Microorganisms Exam Study Guide.
Calvin Cycle function - answer✔to convert ATP into sugars
carboxysomes - answer✔polyhedral cell inclusions inclusions produced by Calvin Cycle
autotrophs.100 nm in diameter, surrounded by a thin, protein shell and consist of a crystalline
array of 250 RubisCO molecules
Rubisco enzyme - answer✔Ribulose biphosphate carboxylase. Catalyzes the formation of two
molecules of 3-phosphoglyceric acid (PGA) from ribulose bisphosphate and CO2.
tetrapyrroles - answer✔Pyrroles are a five-atom ring with four carbon atoms and one nitrogen
atom.Tetrapyrroles are a class of chemical compounds that contain four pyrrole or pyrrole-like
rings. The pyrrole/pyrrole derivatives are linked by (=(CH)- or -CH2- units), in either a linear or
a cyclic fashion.
How chlorophylls differ from cytochromes - answer✔Cytochromes contain an Fe-atom in its
centre, but chlorophylls contain a central Magnesium atom in the ring.
prochlorophytes contain... - answer✔... chlorophyll a and b
cyanobacteria contain... - answer✔....chlorophyll a (a few species contain chlorophyll d)
At low light concentrations purple bacteria can still grow well due to their chlorosomes, which
effectively harvest photons for energy. - answer✔
chlorosomes are present in..... - answer✔anoxygenic green sulfur bacteria, filamentous
anoxygenic phototrophs and photosynthetic Acidobacteria.
carotenoids - answer✔Accessory pigments that broaden the spectrum of colors that can drive
photosynthesis and absorbs harmful forms of oxygen to prevent dangerous photooxidations.
Phycobiliproteins - answer✔Photosynthetic pigments that are the main light-harvesting systems
in cyanobacteria and red algae and is composed of proteins attached to linear tetrapyrroles, called
bilins.
Phycobilisomes - answer✔Aggregates of phycobilisomes
