For the following, fill in the blanks. Most of the terms are from the above bank, and a few are not.
1. The purpose of cell respiration is to __________________________________________, which takes place
in the _____________________________ of the cell. There are _____ major steps.
2. The first step is called _____________________, which takes place in the _________________________.
Its role is to _____________________________ to form ______________ molecules, and has a net of ___
ATP molecules. ___________ molecules are also formed.
3. If oxygen is not present, the process goes into ________________ respiration, or _____________________.
If oxygen is present, then the process continues into ________________ respiration, and converts the
_____________ formed from the first step into _______________________ before starting the second step.
4. The second step of cell respiration is called the ____________________, and takes place in the _________
of the mitochondrion. Its function is to form ______________ & _______________ molecules, and results
in ___ ATP molecules. This step forms _____________ as a by-product.
5. The last step of cell respiration is called the ________________________________, and takes place in the
__________________ of the _________________. It uses the ________________ from the ________ and
_________ molecules of the second step and combines it with ________________ to make up to ____ ATP
molecules, and as a result forms ________________ as a by-product. Altogether, cell respiration makes a
total of up to ____ ATP molecules.
