Metabolism and Cellular Respiration Flashcards
What process is the totality of an organisms chemical reactions?
Metabolism
What begins with a specific molecule and ends with a product where each step is catalyzed by a specific enzyme?
Metabolic pathway
What is the study of how organisms manage their energy resources?
Bioenergetics
What is the capacity to cause change?
Energy
What is the energy of motion?
Kinetic energy
Kinetic energy associated with random movement of atoms/molecules
Heat/Thermal energy
Energy that matter possesses due to its location/structure
Potential energy
What does phosphorylation do?
Adds a phosphate
Partial degradation of sugars that occurs without oxygen
Fermentation
Yields ATP by consuming organic molecules and oxygen
Aerobic respiration
Yields ATP but without oxygen
Anaerobic respiration
What is the first step of cellular respiration?
Glycolysis
What does glycolysis produce?
2 Pyruvate, 2 ATP, Electrons carried by NADH
What must the pyruvate be converted to before it enters the citric acid cycle?
Acetyl CoA
Where does glycolysis take place?
Cytosol
Where do Krebs Cycle and Oxidative phosphorylation take place?
Mitochondrion
What does the citric acid cycle produce after every round?
2 ATP, 6 NADH, 2 FADH2
Where do the electrons that are carried by NADH and FADH2 go?
The ETC
What does the last part of the citric acid/Krebs cycle produce?
32-34 ATP
What causes oxidative phosphorylation?
Redox reactions
Where is the ETC located?
Crista of the mitochondrion
In this process: H+ moves around a bunch
Chemiosmosis
