Cellular Respiration
Where does cellular respiration take place?
Aerobic Respiration takes place w/oxygen
Anaerobic respiration takes place w/o oxygen
W/o oxygen, lactic acid fermentation takes place in the muscles
In glycolysis, the pyruvate is further broken down in lactate (3 carbon moecule)
Accepts electrons to make more NAD+, which can be recycled
In bacteria, alcoholic fermentation occurs
Pyruvate is broken down into ethyl alcohol/ ethanol
Produces CO2
Takes place in the mitochondria bc doing it inside our body can cause us to bust into flames/controlled environment
What are the steps of cellular respiration?
Krebs Cycle
2 carbon in acetyl COA are broken down into CO2
Produces 2 ATP and adds energy to NADH and FADH2
NADH and FADH2 carry high energy electrons to the ETC
Energy Transport Chain
Electrons move through a series of proteins
For each electron that goes through, the proteins pump 1 proton (hydrogen ions) into the inner membrane space
Oxygen we breathe moves into the matrix and becomes the last electron acceptor
Protons flow through the ATP synthase and combine w/ the electrons and oxygen to make water
As many as 32-34 ATP are created
Electrons are added to other protons and the oxygen we breathed in to make H2O as a byproduct
Creates a lot of positive charged Hydrogen ions in the inner membrane (pushes out 2 (FADH2) or 3 (NADH) protons)
Ions have no place to go but the ATP synthase, generating ATP
Glycoysis- Takes place outside of mitochondria in the cytoplasm
1 Glucose (6 carbon sugar)
2 pyruvate (3 carbons each)
Generates: ATP (1 glucose = 2 ATP) and NADH (high energy electrons and protons are stored)
Pyruvate enters mitochondria
Pyruvate dehydrogenase complex converts the 3 carbon pyruvate into acetyl COA (2 carbon molecule)
Produces CO2 in the matrix
What is cellular respiration used for?
When the glucose is broken apart, the hydrogen on the outside falls and bonds w/the oxygen to produce energy for ATP
Oxygen has a lot of energy because it attract electrons
