the measure of heat energy in food
process that releases energy by breaking down glucose and other food molecules in the presence of oxygen
process that requires oxygen
process that does not require oxygen
first set of reactions in cellular respiration in which a molecule of glucose is broken down into two molecules of pyruvic acid
NAD+ (nicotinamide adenine dinucleotide)
electron carrier involved in glycolysis
second stage of cellular respiration in which pyruvic acid is broken down into carbon dioxide in a series of energy-extracting reactions
innermost compartment of the mitrochondrian
process by which cells release energy in the absence of oxygen
In the mitochondria

Is fermentation an anaerobic or aerobic process?
Fermentation allows which process to continue?
in the cytoplasm
Where does fermentation take place?
Lactic Acid and Alcohol
What are the two types of fermentation?
What does lactic acid fermentation produce?
enzymes and pyruvate
What are the requirements for lactic acid fermentation?
muscles feel sore
What happens when lactic acid builds up?
ethyl, alcohol, CO2
What are the products of alcoholic fermentation?
What are the requirements of alcoholic fermentation?
in yeast and some bacteria
Where does alcoholic fermentation occur?
they make alcohol
Why are yeasts used in wine and beer production?
What evidence is there that yeasts give off CO2 in anaerobic respiration?
What processes occur in oxygen poor cells?
lactic acid; the oxygen eventually gets there and cellular respiration takes place

This process produces two molecules that carry energy to the third part of cellular respiration
Which process produces the most ATP per molecule of glucose?
Electron Transport Chain
This is made of proteins that need energy-carrying molecules from the Krebs Cycle and oxygen to make ATP
