Exam 2 Energy Production Flashcards
Four energy storage molecules in the cell.
ATP, NADH, NADPH, FADH
Proteins that catalyze reactions but are not consumed by the reaction.
Enzyme
Breaking down molecules for energy.
Catabolism
Using energy to build cell components.
Anabolism
Balance between catabolism and anabolism. Central biochemical pathways used for both.
Metabolism
Requires an inorganic electron receptor.
Respiration
Metabolic process to convert solar energy into chemical energy.
Photosynthesis
Membrane-embedded system using electron donors and acceptors to create an ion potential.
Electron transport system
Three cellular functions powered by the proton motive force (PMF).
ATP synthase, ion transport, flagella motion
Energy is derived from compounds that do not contain any carbon.
Lithotrophy
Energy is derived from the breakdown of compounds comprised of carbon.
Organotrophy
Three glucose catabolism pathways.
Glycolysis (EMP) (prokaryotic and Eukaryotic), Enter-Doudoroff (ED) (prokaryotic), Pentose phosphate shunts (PPS) (prokaryotic and Eukaryotic)
Catabolism without the electron transport system.
Fermentation
Generates a proton gradient that powers ATPase to produce ATP.
Proton motive force
Two general components of metabolism.
Anabolism, Catabolism
Molecule that contains two high-energy bonds used for energy requiring reaction in the cell.
ATP
Possible terminal electron acceptors in inorganic respiration.
Oxygen, Nitrate, Sulfate
Use light energy to reduce compounds.
Phototrophy
Electron flow that generates a proton motive force (PMF).
Electron transport system
ATP-producing membrane-bound complex driven by proton motive force (PMF).
ATP synthase
Using inorganic molecules for energy.
Lithotrophy
Oxidation of hydrogen to form methane.
Methanogens
