Self Quiz for Energy

Study the material in this section and then write out the answers to these question.
Do not just click on the answers and write them out. This will not test your understanding of this tutorial.

1. What is energy and why is it required by cells? (ans)

2. The energy found within the chemical bonds of nutrients and ATP is an example of:

a. potential energy (ans)
b. kinetic energy (ans)

3. Is the following statement true or false?

During photosynthesis, cells of plants and algae create energy from sunlight. (ans)

4. During photosynthesis, the energy in photons from the sun are converted into the energy in the chemical bonds of glucose and other organic molecules. During cellular respiration, the energy in the chemical bonds of glucose and other organic molecules can then be converted into energy in the chemical bonds of ATP, the form of energy most commonly used to do cellular work. The ability to do this is based on:

a. the first law of thermodynamics (ans)
b. the second law of thermodynamics (ans)

5. After exercising, you body feels hot. Explain this in terms of the laws of thermodynamics. (ans)

6. The synthesis of DNA and proteins is an example of:

a. a catabolic reaction (ans)
b. an anabolic reaction (ans)

7. As will be seen later, during glycolysis, one molecule of glucose is converted into two molecules of pyruvate, 2 NADH + 2H⁺, and two net ATP. This is an example of:

a. a catabolic pathway (ans)
b. an anabolic pathway (ans)

8. The energy-requiring synthesis of proteins from amino acids is an example of:

a. an endergonic reaction (ans)
b. an exergonic reaction (ans)

9. Organisms that carry out use light as an energy source and carbon dioxide as their main carbon source are called:

a. photoheterotrophs (ans)
b. chemolithoautotrophs (ans)
c. photoautotrophs (ans)
d. chemooganoheterotrophs (ans)

10. Organisms that use organic compounds as both an energy source and a carbon source are called:

a. photoheterotrophs (ans)
b. chemolithoautotrophs (ans)
c. photoautotrophs (ans)
d. chemooganoheterotrophs (ans)
