What is the total energy tally after one round of the Krebs cycle has been completed?
What is 4 NADH molecules, 1 FADH2 and one ATP
100
Where does the third phase of respiration take place?
What is inner mitochondrial membrane?
100
Where and how is water produced during cellular respiration?
It is produced during the electron transport chain by the addition of low energy electrons to oxygen and hydrogen ions
200
The products of glycolysis
What is ATP, Pyruvic acid and electrons carried in NADH
200
Who is the Krebs cycle named after? (I need a first name)
Who is HANS Krebs
200
What is the name of the molecule that reacts with Acetyl-coA to form citric acid?
What is oxaloacetate
200
What happens that causes NADH to change to NAD+ and FADH2 to change to FAD?
The electron carriers give up their high-energy electrons to the carrier proteins on the electron transport chain
200
Why do runners breath heavily after a race?
They need extra oxygen to get rid of lactic acid that has built up in their muscles
300
Come to the board and write down the equation for cellular respiration
oxygen + glucose yields carbon dioxide + water + energy
300
Which molecule gets broken down into carbon dioxide during the Krebs cycle?
What is pyruvic acid
300
What happens to the carbons that are broken off larger molecules during the Krebs cycle?
What is they are turned into carbon dioxide
300
What happens to the electrons that have lost energy?
They are passed on to the final electron carrier which is oxygen - here they are used along with H ions to make water
300
Where does the carbon dioxide in your breath come from? (BE SPECIFIC)
From the reactions in the Krebs cycle when one carbon atom from pyruvic acid becomes part of a molecule of carbon dioxide
400
What are two advantages of glycolysis
What is the quick production of ATP (thousands in milliseconds) and that it does not require oxygen
400
How many ATP molecules are produced per molecule of glucose during the Krebs cycle?
What is TWO
400
Where does the Krebs cycle take place?
What is mitochondrial matrix
400
How is the difference in charge on either side of the membrane used to produce ATP molecules?
The charge differences cause hydrogen ions to pass through ATP synthase in the membrane and the energy released during that passing converts ADP into ATP
400
What is a calorie?
The amount of energy needed to raise the temperature of 1 gram of water 1 degree Celsius
500
What are the equations for alcoholic fermentation and lactic acid fermentation?
