Lec6 Flashcards
Krebs cycle or TCA cycle occurs in?
Cytoplasmic membrane.
Results of Glycolysis?
- 2 pyruvate
- 2 ATP
- NADH = 6 ATP
Types of respiration:
1.Aerobic respiration 2.Anaerobic respiration
Is second phase of aerobic respiration
Kerbs cycle/ TCA Cycle
Electron transport chain occurs in?
Plasma membrane
Coenzyme drived from vitamin B2 (riboflavin)
Flavoprotein (carrier molecules)
Protein with iron contain group (heme)
Cytochromes (Carrier molecules)
Small non protein carriers
Ubiquinones (carrier molecules)
ATP generation from anaerobic respiration always higher than aerobic respiration.
T/F
F, less than
Organisms that can’t respire because of lack of inorganic electron acceptor/absence of ETS Used what?
Fermentation
Electron ecceptor in fermentation is always?
Organic compounds
Aerobic respiration electron acceptor is
O2
Anaerobic respiration electron acceptor is
Inorganic molecule, except O2
From substantial amounts of products than lactate, many produce lactate,ethanol, co2.
Heterolactic.
Reduce almost all their pyruvate to lactate with enzyme lactate dehydrogenase
Homolactic
Analysis of end product is valuable in identifying particular bacteria.
Fermentation
- role in heat stability of endospores
- stabilize cell walls in microbes
Calcium (Ca)
-Stabilizes ribosomes, membranes, and nucleic acids - - -required for many enzymes
Magnesium (Mg)
Distinguishes between a given group of Bacteria
Differential Media
Contain complex media plus addotionalnutrients
Enriched media
Exact composition
Defined Media
Why all living cells depend on biochemical reactions ?
to maintain homeostasis
reactions that “break down” molecules generally energy releasing or exergonic
catabolic
reactions that build new molecules
anabolic
How enzyme are work?
By lower the activation energy (E a)
Photophosphorylation occurs in?
In Phototrophs
