3.2.6 In Search of Energy

What is the primary source of ATP energy for living cells?

• Carbohydrates

• Lipids

• Proteins

• Nucleic acids

The body needs a quick and easily accessible source of ATP all the time. In fact, ............???.......... million molecules of ATP are used and regenerated per second per cell!

• 1

• 5

• 10

• 15

Where is the energy located in the ATP molecule?

• In the bonds between ribose sugar and adenine base

• in adenine base

• In the bonds between each of the phosphate groups

• in ribose sugar

What do we call the type of chemical reaction that occurs in the following equation

ATP + H₂O → ADP + P_i + energy

• Hydration

• Hydrolysis

• Condensation

• Cellular respiration

What is ADP and how is it genertaed?

• ADP stands for "adenosine diphosphate" and it is generated by removing one of the three phosphate groups in an ATP

• ADP stands for "adenosine diphosphate" and it is generated by cellular respiration

• ADP stands for "adenosine triphosphate" and it is generated by removing two phosphate groups in an ATP

• ADP stands for "adenosine diphosphate" and it is generated by mitochondria

Which of the following is the name of process in which the human cells generate ATP. Where in the cell does this process occur?

• Cellular respiration in ribosomes

• Aneorobic cellualr respiration in mitochondria

• Aerobic Cellular respiration in mitochondria

• Fermentation-in cytoplasm

• We get C6H12O6 (glucose) from eating food, especially vegetables, and we get O2 (oxygen gas) from breathing.

• We get C6H12O6 (glucose) from eating food, especially lipids, and we get O2 (oxygen gas) from breathing.

• We get C6H12O6 (glucose) from eating food, especially proteins, and we get O2 (oxygen gas) from breathing.

• We get C6H12O6 (glucose) from eating food, especially carbohydrates, and we get O2 (oxygen gas) from breathing.

Which types of cells in the body would you expect to require the most ATP?

• Muscle cells

• Skin cells

• Exocrine glandular cells

• Endocrine glandular cells

You hear someone mention the molecule "AMP." Based on what you learned about the structure of ATP and the way in which energy is released, what do you think AMP stands for and how do you think it would be created?

• AMP would stand for "adenosine phosphate" and it would be created by removing one phosphate groups from the original ATP molecule.

• AMP would stand for "adenosine monophosphate" and it would be created by removing two phosphate groups from the original ATP molecule.

• AMP would stand for "adenosine dihosphate" and it would be created by removing three phosphate groups from the original ATP molecule.

• AMP would stand for "adenosine monophosphate" and it would be created by removing all phosphate groups from the original ATP molecule.

What type of sugar is there in the structure of ATP?

• Glucose

• Deoxyribose

• Ribose

• Adenine
