EMP/ Aerobic Respiration>bridge>Krebs>ETC Flashcards
After EMP occurs you have 2 pyruvic acid molecules within the cell (3 carbons each) what 2 factors determine what happens next?
Is O2 available? What type of organism we have?
Through a process of aerobic respiration most organisms will do this
bridge reaction
Where does the bridge reaction takes place in bacteria?
cytoplasm
One step between the EMP and the Krebs cycle (conversion reaction)
bridge reaction
What is the product of the bridge reaction?
Acetyl CoenzymeA molecule
Through the process of the bridge reaction what molecule is also made?
2 NADH
Where does the Krebs cycle takes place?
cytoplasm
Cannot start with pyruvic acid and you need Acetyl CoenzymeA molecules
Krebs cycle
Krebs cycle is also known as the?
citric acid cycle
Krebs cycle creates alot of energy? TRUE or False
TRUE
1st reaction AcetylCoA joins with _____ to create Citric acid
oxaloacetate
AcetylCoA (2 carbons) + Oxaloacetate (4 carbons) =
Citric acid (6 carbons)
Krebs Cycle Energy per cycle produces?
1 ATP;3 NADH; 1 FADH2 (* intermediate energy)
Krebs Cycle Energy per glucose (EMP) produces?
2 ATP; 6 NADH; 2 FADH2 (* intermediate energy)
Electron Transport Chain takes place in the?
Plasma Membrane
Electron Transport Chain needs a source of electrons which are intermediate energy used to make ATP such as?
NADH; FADH2 both supply the electrons as H
What are the products of the ETC
ATP
What is the electron carrier molecules that carry the electrons along the membrane?
cytochrome molecules
H from NADH & FADH2 pass it to #1 group of cytochrome molecules (accepts it then releases it) and then passes it to the #2 & #3 is this TRUE or FALSE
TRUE
Is hydrogen stable or unstable at the end of ETC?
unstable
What happens to Hydrogen at the end of ETC?
joins the O2 and produces water
What is the final result of the ETC?
O2 is the final electron acceptor
