Question 1

Points: 10 out of 10

True or False: The hydrolysis of AMP (adenosine monophosphate) will release similar amount of energy as the hydrolysis of ATP or ADP.

•             True

•             False

Question 2

Points: 10 out of 10

How does the energy content of ATP and ADP differ?

•             ADP is a higher energy molecule than ATP

•             ATP and ADP contain the same amount of energy

•             ATP is a higher energy molecule than ADP.

Question 3

Points: 0 out of 10

Where is the chemical energy of ATP mainly stored?

•             In the bond between the ribose and the first phosphate.

•             In the bonds of the ribose.

•             In the bond between the last two phosphates.

•             In the bonds of the adenine base.

•             In the bond between the first two phosphates.

Question 4

Points: 10 out of 10

A cell in your pancreas is synthesizing human insulin protein by joining together amino acids. What input do you think this reaction requires?

•             ATP

•             None of these choices.

•             Water

•             Carbon dioxide

Question 5

Points: 10 out of 10

How does growth work?

•             To grow, a cell must only do anabolic reactions. Simpler food molecules are taken in and strung together to make more complex molecules of the cell.

•             To grow, a cell must do both catabolic and anabolic reactions. Organic food molecules are not complex enough to be used for growth. Therefore anabolic and catabolic reactions must be done to make the molecular structure more complex.

•             To grow, a cell must simply take in complex organic molecules and store them. You are exactly what you eat.

•             To grow, a cell must do both catabolic and anabolic reactions. Food molecules must be partly broken down and then rebuilt in new forms to enable growth; you aren’t exactly what you eat.

•             Catabolic

•             Anabolic

Question 7

Points: 10 out of 10

Indicate whether DNA synthesis is a catabolic or anabolic process.

Question 8

Points: 10 out of 10

Energy is defined as:

•             The ability to increase the temperature of something.
