Chapter 9 Flashcards
What is the first step in Cellular respiration that begins releasing energy stored in glucose?
Glycolysis
The carriers for energy and high-energy electrons during glycolysis are…
NADH
If oxygen is not present, glycolysis is followed by…
Fermentation
Name the three carbon molecule produced when glucose is broken in half during glycolysis.
Pyruvic acid
Since fermentation does not require oxygen it is said to be…
Anaerobic
Which high-energy electron carrier is regenerated during fermentation that allows cells to continue to make ATP using Glycolysis?
NAD+
How many ATP molecules are added to get glycolysis started?
Two
Since glycolysis produces for ATP molecules, this results in a net gain of… ATPs
Six
Cellular respiration formula…
6O2 + C6H12O6 = 6CO2 + 6H2O + Energy
Alcoholic Fermentation Formula…
Pyruvic acid + NADH = alcohol + CO2 + NAD+
Lactic acid fermentation formula…
Pyruvic acid + NADH = Lactic acid + NAD+
What is the correct sequence during cellular respiration?
Glycolysis, Krebs cycle, electron transport chain
Where do the carbon atoms in pyruvic acid and following the Krebs cycle?
They become part of the carbon dioxide molecule and end up in the atmosphere
Because cellular respiration requires energy it is said to be…
Aerobic
How many total ATP molecules are produced by one molecule of glucose completing the cellular respiration
Two
