Glycolysis
Where does glycolysis occur? Why?
cytoplasm: produce energy in the absence of oxygen
How many NADH are produced per glucose in the Krebs Cycle? Where do they go, specifically?
8 NADH, inner membrane of mitochondria/protein carriers
How many total ATP are produced during the ETC
32 ATP
How many NADH molecules for glycolysis?
2 NADH
What is the equation for glycolysis?
Glucose + 2ATP +2NAD+ ---->2 pyruvate 4ATP 2NADH
How many total ATP are produced during glycolysis?
How many ATP are produced per pyruvate?
They use their high energy to transport Hydrogen ions (active transport w/out ATP) into the intermembrane space providing a beneficial concentration gradient
How many net ATP for glycolysis
2 ATP
What are the products of one turn of the krebs cycle?
4NADH, 1FADH2, 3CO2 1ATP
What happens when glycolysis releases thousands of ATP in a matter of seconds?
How much CO2 is released per glucose?
6CO2
Why does FADH2 drop it's electrons off after NADH?
The FADH2 acts as a high energy electron booster providing more energy and more hydrogen ions into the concentration gradient
How many cycles of krebs happen per glucose?
2
What is the full equation for lactic acid fermentation?
Glucose + 2ATP + 2NADH -----> 2 Pyruvate + 4ATP ------->2Lactic Acid + 2NAD+
To break glucose into two pyruvate
How many FADH2 are produced per pyruvate? Where does it go, generally?
1 FADH2, ETC
This type of movement drives ATP Synthase
The facilitated diffusion of H+ ion
How many hydrogen ions are diffused through the innermembrane and ATP synthase?
32
What is the equation for the krebs cycle per glucose
2 pyruvate + 2 CoA + 8NAD+ + 2FAD+ 2ADP ------> 4 carbon compound 8NADH 2FADH2 2ATP 6CO2
3: Lactic Acid Fermentation, Alcoholic Fermentation and Krebs Cycle
Why is the krebs cycle essential to the production of energy in the ETC?
The large amounts of electron carriers move to the ETC to supply High energy electrons, Hydrogen Ions and allow facilitated diffusion to turn ATP Synthase
What is the equation for the electron transport chain per glucose
10 NADH + 2FADH2 -----> 6H20 + 32 ATP + 10 NAD+ + 2FAD+
How many times have we talked about cellular respiration?
Too many
What is the equation for the ETC?
10 NADH + 2 FADH2 -----> 10 NAD+ + 2 FAD+ + 6H20 + 32 ATP
