Chapter 9 Assessment
Biology:
1. In cells, the energy available in food is used to make an energy-rich compound called? Glucose

2. The first step in releasing the energy of glucose in the cell is known as? Glycolysis

3. The process that releases energy from food in the presence of oxygen is? ATP Synthase

4. Which organisms preform cellular respiration?
All of the above

5. The net gain of energy from glycolysis is?
4 ATP molecules

6. Because fermentation takes place in the absence of oxygen, it is said to be? Anaerobic

7. The Krebs cycle takes place within the?
Mitochondria

8. The electron transport chain uses the high- energy electrons from the Krebs cycle to? Convert ADP to ATP

9. A total of 36 molecules of ATP are produced from 1 Molecule of glucose as a result of? Lactic acid Fermentation

10. During heavy exercise, the buildup of lactic acid in the muscle cells results in? The Krebs cycle

11. What is a calorie? How do cells use the high- calorie molecule such as glucose? A calorie is the amount of energy that is needed to raise the temperature of water to a Celsius. The cells use the high-calorie molecule to release the energy from glucose and other food compounds.

12. How is glucose changed during glycolysis? What products are produced as a result of glycolysis? It releases little amounts of energy then it will take two pathways that release a great deal of energy (if it has oxygen) If it doesn’t, then the glycolysis will be followed into a different pathway. 13. What are the two pathways that might follow glycolysis? What factor can determine which of those pathways a cell might follow? The two pathways that might follow glycosis are ATP production and NADH production that vary according to the amount of energy and oxygen.

14. Use formulas to write a chemical equation for cellular respiration. Label the formulas with the names of the compounds 6O2 + C6H12O6 --> 6H2O + 6CO2 + energy

15. Draw and Label a...
