Lecture 11 Flashcards
Anabolism
Builds up. Requires energy input. Condensation and reduction. Delta G>0
Catabolism
Breaks down. Releases energy. Hydrolysis and oxidation
Oxidation
Loss of electrons
Reduction
Gain of electrons
Reducing Power
Transferring energy with electrons
Enzyme
It is a catalyst. Large biological molecules responsible for thousand of chemical interconversions. Work best near max temp
Active Site
Place where the substrate binds to the enzyme.
Induced Fit
A change in the shape of the active site to allowed the substrate to bind more tightly
Competitive Inhibitor
A pocket in the enzyme that only fits a certain substrate and only that certain substrate can bind there.
Noncompetitive (allostreric) inhibitor
A different site from the active site. Inhibitors do not resemble the substrate at all, and interact with another part of the enzyme to cause a shape change by induced fit
Central Catabolism
Breaks down molecules into smaller units to release energy. Needs glycolysis, pyruvate oxidation, and TCA cycle
Glycolysis
Oxidizes glucose and produces ATP, pyruvate and NADH(electrons)
Oxidative Decarboxylation of pyruvate
Releases CO2 and produces electrons
Electron Carrier (NAD/NADH)
A molecule capable of accepting one or more electrons from another molecule, and then transfer these electrons to donate to another during the process of electron transport.
Acetyl CoA
an important molecule in metabolism. Its main function is to convey the carbon atoms within the acetyl group to the citric acid cycle (Krebs cycle) to be oxidized for energy production.
