Reactions
This form of energy is stored in the chemical bonds of molecules.
What is Chemical Potential Energy?
The overall purpose of cellular respiration is to turn food (glucose) and O2 into u____ e____.
What is useable energy?
Location in the cell where the last two steps of cellular respiration take place.
What is the mitochondrial matrix?
This type of reaction uses water as a reactant to slice another molecule into two.
What is hydrolysis?
This stage of cellular respiration takes place in the cytoplasm of the cell.
What is glycolysis?
The names of the last two steps in cellular respiration.
What are the Krebs cycle and oxidation phosphorylation (electron transport chain)?
This is the 'energy currency' in the cell.
During glycolysis, a small amount of ATP (and NADH) is produced along with these two important molecules.
What are pyruvic acid molecules?
A series of reactions (involving a cycle of 4-, 5- and 6- carbon compounds) results in production of CO2 and these important 'energy' molecules.
A reaction in which the potential energy of products is lower than the potential energy of the reactants.
What is an exothermic reaction?
The name of the cofactor which is produced in the mitochondrial matrix from a 3-carbon reactant.
What is acetyl-CoA?
The transfer of electrons from high energy electron carriers (NADH and FADH2) down membrane-bound protein complexes allows formation of a H+ concentration gradient in the intermembrane space which then diffuses back into matrix to facilitate this reaction.
What is the conversion of ADP to ATP?
A biological catalyst which lowers the activation energy of a reaction.
What is an enzyme?
The name of the 'energy' molecule which is produced by the oxidation of pyruvate.
What is NADH?
The final electron acceptor in the electron transport chain.
What is oxygen (O2)?
