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
Where does cellular respiration take place?
Is cellular respiration aerobic or anaerobic?
cellular respiration equation is...

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
What causes muscles soreness? What eventually causes it to go away?
Where is lactic acid produced?
the substance you start with and undergoes change in a reaction
What is a reactant?
The Kreb's Cycle
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
Up to how many ATP molecules are made from the breakdown of one glucose molecule?
Is NADH performed during the Krebs Cycle?
What chemical reaction has almost the same products and reactants as cellular respiration but reversed?
The folding of the inner membrane in the mitochondria is called the..
a molecule formed at the end of glycolysis
What is pyruvate?
oxygen and glucose
What reactants are there in cellular respiration?
What acts as an electron carrier in cellular respiration?
The Krebs Cycle takes place within the...
ATP, water, carbon dioxide
What are the products of cellular respiration?
the electron transport chain
Water is an end product of...

Which is needed for glycolysis to occur?
What process is found in both aerobic and anaerobic metabolism?
the substance that is formed after a chemical reaction
What is a product?
