Microbiology Chapter 5 Flashcards
Metabolic pathway?
Determined by enzymes is a sqquence of enzymatic activty catalyzed chemicam reactions in a cell
Define metabolism, catabolism and anabolism?
The sum of chrmical reactions in an organism
Provides energy and building blocks for anabolism
Uses energy amd building nlocks to build large molecules
Enzyme collision theory components.
States that chemical reactions can occur when attoms, ions and molecules collide
Enzyne components? As a catalyst turnover number of 1:10000
Apornzyme, cofactors: nad+,nadp+ fad and conenzyme a
Apoenzyme:protein
Cofacyor: nonorotei. Component
Halienzyme:apoenzyme+cofactor
Enzyme classification: oxidoreducrase,teansferase,hydrolase,lyase,isomerase,ligase, ribozymes
Oxidation reduction equations
Transfer functional group
Hydrolysis
Removal of atoms w/o hydrolase
Rearrangement
Joining if molecules uses atp
Rna that cuts and splices rna
Factors influencing enzyme activity?
Temperature, ph, substrate, inhibitors
Types of enyme inhibition
Conpetitive and noncompetitive inhibition
- feedback inhibiton
Oxidationreduction terms:
Oxidation
Reduction
Redox reactions
Biologic oxidations are usu dehydrogenations
Removal of electro s
Gain electrons
An oxidation reactionwith reduction reaction
Generation of atp dine by phosphorylation of adp: substrate level,oxidatice phosphorylation: phosphorylation
Substrate: Energy from the transfer pf po4 to adp
Oxidative pho:energy released from oxidative reduction teaction in the Electron transport chain
Phosphorylation: light causes chlorophyll to give up electrons
Carbohydrate metabolism:
Glycolysis (EM pathway)
Oxumidation of glucose to pyruvic acid producedms atp and nadh
Route from aerobic to anaerobic repuration
Glycolysis, intermediate reaction, krebs cycle,ETC
Alt to glycolysis
Pentose phosphate payhway(with glycolysis) and entner dourdoff pathway(w/o glycolysis)
ETC series of carrier molecules are oxidizrd and reduced as electrons passed down the chain
Energy release produced atp by chemiosis
Kinds of respiration? What are the differences
Final electron acceptor in etc is oxygen
Final electron transport in etc is not oxygen(yields less)
Fermentation science definition:
Releases energy from oxidatiion of organic molecules
No oxygen required
No need of krebs and etc so low production
Use organic final electron acceptor
