What is cellular respiration?
|
process in cell that breaks down glucose to produce energy in form of ATP
|
|
|
What is the importance of cellular respiration?
|
provides all organisms with energy; includes plants as well as animals/other organisms
|
|
|
Where does cellular respiration occur?
|
the mitochondria

|
|
What is the general equation for Cellular Respiration?
|
6O2+C6H12O6->6H2O+ATP

|
|
Where does glycolysis occur?
|
the cell cytoplasm
|
|
|
What is glycolysis?
|
the process which breaks down glucose through a series of reactions to produce pyruvic acid

|
|
Where does the Krebs cycle occur?
|
the mitochondria
|
|
|
What happens to pyruvic acid in the Krebs cycle?
|
undergoes a series of reactions
|
|
|
What are the products of the Krebs cycle?
|
carbon dioxide, ATP, NADPH, FADH2
|
|
|
Where do NADH and FADH transport electrons to in the Electron Transport Chain?
|
the electron transport chain
|
|
|
Where is the electron transport chain located?
|
the inner mitochondrial membrane
|
|
|
What happens as the transport chain accepts the electrons?
|
hydrogen ions are transported across the inner mitochondrial membrane
|
|
|
What do the movement of Hydrogen ions across the membrane in the Electron Transport Chain produce?
|
ATP
|
|
|
What is the final acceptor of electrons?
|
a hydrogen ion combining with oxygen to form water
|
|
|
What is anaerobic respiration also known as?
|
fermentation
|
|
|
What is anaerobic respiration?
|
respiration without oxygen
