Week 7 Vocabulary Flashcards
Electrically Conductive Pili
Long, thin structures made by just a few bacteria that transport electrons from respiration to extracellular electron acceptors
NADPH
Electron carrier for anabolic reactions
Heterotroph
Bacteria that uses organic compounds as a carbon source
Autotroph
Bacteria that uses inorganic compounds as a carbon source
Calvin Cycle
Most common pathway for bacteria to fix CO2
Ribulose 1,5-bisphosphate
First molecule in Calvin Cycle; 5 carbon sugar
RuBisCo
Enzyme that incorporates CO2 into ribulose 1,5-bisphosphate
Reductive Pentose Phosphate Pathway
Another name for the Calvin Cycle
Glutamate Dehydrogenase
Incorporates ammonia into alpha-ketoglutarate to make glutamate
Glutamate Synthase
Incorporates ammonia into glutamate into glutamine
Transaminase
Transfers amine from glutamate to oxalocetate to make aspartate
Nitrogenase
Enzyme which makes ammonia from nitrogen gas
Flavodoxin
Protein which transfers electrons from pyruvate to nitrogenase
Dinitrogenase Reductase and Dinitrogenase
Two activities contained within the nitrogenase enzyme
Heterocyst
Thick-walled cell that does not use aerobic respiration; protect nitrogenase
Assimilation
Incorporation of inorganic molecules into organic scaffolds
PAPS
Phosphoadenosine 5’-phosphosulfate
