Glycolysis
first step in cellular respiration that begins releasing energy stored in glucose
NADH
The carriers for energy and high energy electrons during GLYCOLYSIS
fermentation
If oxygen is NOT present, glycolysis is followed by
pyruvic acid
Name the 3 carbon molecule produced when glucose is broken in half during glycolysis
2
How many ATP molecules are added to get glycolysis started?
2
Since glycolysis produces 4 ATP molecules, this results in a NET GAIN of
C6H12O6 + O2 → CO2 + H2O + ATP
Write the complete overall chemical equation for cellular respiration using chemical symbols instead of words
Glycolysis → Krebs cycle → Electron transport chain
Which of the following shows the correct sequence during cellular respiration?
They become part of a carbon dioxide molecule and end up in the atmosphere
Where do the carbon atoms in pyruvic acid end up following the Krebs cycle?
36
How many total ATP molecules are produced by 1 molecule of glucose completing cellular respiration ?
ATP, NADH, FADH2, CO2
WHICH OF THE FOLLOWING ARE PRODUCED DURING THE KREBS CYCLE?
oxygen
What molecule is the final electron acceptor at the end of the Electron transport chain?
H+ ions
The movement of which ion across the membrane from the intermembrane space to the matrix causes ATP synthase to spin and make ATP
Electron transport
Which stage of cellular respiration produces the most ATP?
Energy from the moving electrons transports H+ ions into the intermembrane space’, Energy from H+ ions crossing back into the matrix causes ATP synthase to make ATP, Water is produced
Which of the following happens as electrons pass down the Electron Transport chain?
Its electrons will enter the transport chain
If oxygen is present, what will happen to the NADH produced in this reaction?
cristae
The folded inner membranes inside a mitochondrion are called
acetyl CoA
forms when Coenzyme A attaches to two carbons from pyruvic acid
intermembrane space
As electrons pass down the electron transport chain, H+ ions build up in the
glycogen
the storage form of glucose used by animal cells which can be broken down for energy when glucose is used up
alcoholic/ethanol and lactic acid
2 types of fermentation
glucose + (NAD+) yields (ethanol) + CO2 + ATP
equation for alcoholic fermentation
glucose + (NAD+) yields (lactic acid) + ATP
Lactic acid equation
