This type of fermentation takes place in unicellular organisms and some plant cells
What is alcoholic
100
These two molecule combine to form citirc acid in step one of the krebs cycle.
What is oxaloacetate, and acetyl CoA
100
The ETC takes placer here
What is in the inner mitochondrial membrane.
100
Pyruvic acid will enter this pathway during aerobic conditions
What is Krebs cycle
200
This molecule enters Glycolysis from our diets.
What is Glucose
200
Pyruvic acid undergoes a redox reaction with this molecule to become lactic acid.
What is NADH
200
This byproduct of the krebs cycle is diffuses out of the cell and is exhaled by the body.
What is CO2
200
What is the energy lost by the movement of electrons through the chain used for?
What is to pump H+'s across creating a concentration gradient.
200
Purivic acid must be converted to this before it enters the krebs cycle
What is acetyl CoA
300
This is the product of glycolysis.
What is pyruvic acid
300
Fermentation takes place under these conditions
What is anaerobic (low or no oxygen)
300
In step 4 of the krebs cycle this molecule accepts high energy electrons through a redox reaction.
What is FAD
300
How do electrons move from molecule to molecule in the ETC.
What is through redox reactions.
300
Why do people breath?
What is O2 is inhaled to accept electrons in the ETC, CO2 is release from organic molecule in the krebs cycle and exhaled.
400
This molecule is formed during glycolysis and photosynthesis.
What is G3P
400
This type of fermentation can be used in the manufacturing of yogert, cheese, ect.
What is lactic acid
400
The krebs cycle takes place here
What is in the mitochondrial matrix
400
Explain how the ETC in the mitochondria is different than the one in the thylakoids.
What is the ETC in the mitochondria does not have photocenters and does not have a water splitting enzyme. It accpets high energy electrons from NADH, and FADH2
400
This is the total number of ATP produced from 1 glucose molecule, assuming oxygen is present.
What is 38
500
Explain what takes place in step 1 of Glycolysis
What is Two phosphate groups are attached to the six carbon molecule. The phosphate groups come from ATP.
500
Why is lactic acid fermentation so important to our cells, and body.
What is it regenerates NAD+ which is needed to keep glycolysis runing.
500
What is the relationship between the krebs cycle and the ETC
The Krebs cycle provides high energy electrons, carried by NADH and FADH2, to the ETC, which powers the pathway as it pumps H+ across to create a concentration gradient.
500
Explain how the ETC is connecte to chemiosmosis.
The ETC produces the H+ concentration gradient that allows ATP synthase to opperate. ATP synthase attaches a phosphate to ADP.
500
Why can't the krebs cycle, the ETC, and ATP synthase work without oxygen. What happens with no oxygen?
What is there will be no electron acceptor, thus the pathways will back up and stop working.
