Metabolism Flashcards
Kinetic energy
Energy of motion
Potential energy
Stored energy
Catabolic reactions and ex
Energy is released
Complex molecules are broken down to simpler molecules
Ex cellular respiration
Anabolic reactions
Energy is absorbed
Simpler molecules combine to build molecules more complex
Two laws of thermodynamics
Energy cannot be created or destroyed but only converted from one form into another
During any process, the universe tends toward disorder
Exergonic
Energy is released
Catabolic
Endergonic
Absorbs energy
Anabolic
First stage of cellular respiration
Glycolysis
Broken down because of oxygen
One molecule of glucose to two smaller molecules of pyruvate
Where does glycolysis take place
Cytoplasm
Goal of glycolysis is to
keep glucose from diffusing out of cell
Products of glycolysis
2 NADH and ATP
two pyruvate
Stage two of respiration
Pyruvate oxidation
Where the pyruvate Is converted to acetyl-CoA
Products?
Stage 3 of respiration
Krebs cycle
Oxidizes acetyl-CoA
Products of Krebs cycle?
H
Anaerobic respiration
Only use glycolysis, need a way to reoxidize NADH or they will run out of NAD+
