1. Explain what happens when cells break down food molecules.
2. ATP is a type of what? What is it used for?
3. Name the substances produced by photosynthesis:
4. Name the 4 organic compounds from Chapter 3
5. Which of the organic compounds from the answer above is broken down during
cellular respiration?
6. Name various things that happen when glycolysis occurs:
7. How do cells continue to provide energy for muscles even when Oxygen is not
available?
8. Can glycolysis occur in the absence of oxygen?
9. In what organelle of the cell does respiration begin and in what organelle does
respiration end.
10. ADP+P=?
11. When cells break down molecules, what 2 things can happen to the energy that is
released from the molecule?
12. If 98 kCal of ATP energy is formed, but the original food molecule had a total of
250 kCal of energy in it, how efficient is cellular respiration at extracting energy
(%)?
13. How many molecules of ATP must be produced in the beginning by glycolysis,
to begin the main process of respiration which makes 36 ATP?
14. Describe why photosynthesis and respiration are so closely linked…..
