Chapter 9 - Cellular Respiration Flashcards
What happens during glycolysis?
One molecule of glucose is broken in half producing two molecules of pyruvic acid a three carbon compound.
What is cellular respiration?
The process that releases energy by breaking down glucose and other food molecules in the presence of oxygen.
Where does glycolysis take place?
In the cytoplasm.
How does cellular respiration begin?
With glycolysis.
What is the formula for cellular respiration?
6O2+C6H12O6>6CO2+6H2O+Energy
What are the three main stages of cellular respiration?
Glycolysis, Krebs cycle, electron transport chain.
What are the reactants and products of glycolysis?
Oxygen+glucose = Carbon dioxide + water + energy.
What is purification acid?
Product of glycolysis.
What is NADH?
NAD+ with two high-energy electrons.
What is fermentation?
The process of releasing energy from food molecules by producing ATP in the absence of oxygen.
What happens during alcoholic fermentation?
Yeast and a few other microorganisms use alcohol fermentation forming Ethyl alcohol and carbon dioxide is wastes.
What is lactic acid fermentation?
The process of rapidly producing ATP by using pyruvic acid and NADH to form lactic acid and NAD+.
What happens during the Krebs cycle?
Pyruvic acid is broken down into carbon dioxide in a series of energy extracting reactions.
Where does the Krebs cycle take place?
In the mitochondrion.
What happens to the carbon dioxide released in the Krebs cycle?
You breathe it out.
