chapter 6 Flashcards
Anabolic:
Catabolism
Anabolic reaction uses engegy
Catabolism: Makes Energy
Photosynthetic organisms (phototrophs) harvest energy
in sunlight
Chemoorganotrophs obtain energy from
organic compounds
FREE ENERGY is energy that is available to do
Free energy is energy available to do work
Energy is released when a chemical bond is broken
Exergonic: _____ have more free energy***
Endergonic s : ______ have more free energy
Exergonic reactions: reactants have more free energy***
Energy is released in reaction
Endergonic reactions: products have more free energy
Reaction requires input of energy
***Endergonic reactions are coupled w/ ___?
exergonic eractions
Substrate-level phosphorylation
what Kind of reaction powers it?
Exergonic reaction powers
what drives Oxidative phosphorylation***
Proton motive force drives
Electron Donor + Electron Acceptor
/e
When it donats /e it becomes ____. When Acceptor recieves it it becomes _____.
oxidized
reduced
NAD+/NADH, NADP+/NADPH, and FAD/FADH2 *****
pathways maybe put on note card?
;p
Precursor metabolites are intermediates of
catabolism(make energy that can be used in anabolism
Noncompetitive Inhibition
Feedback Inhibition-
- substrate binds somewhere else on the enzyme and changes shape of enzme’s active shape
- non competitive , if you have too much of F you need to stop that pathway
Competitive inhibitor
Sulfa drugs use to interrupt a Pathway KNOW sulfa EXAMPLE
binds to active site of enzyme, Sulfa drug will bind to an enzyme that
sulfa drugs blocking folic acid synthesis
***Substrate-level phosphorylation what happens
Oxidative phosphorylation
what happens
-
Exergonic reaction powers. ADP uses a substrate to bind to an active site. to make ATP
During oxidative phosphorylation, Proton motive force drives protons into the cell to make ATP
