The diagram shows the molecular structure of adenosine triphosphate (ATP) Which of these events occurs during the normal function of ATP in the cell?

• A chemical bond forms between the adenine unit and the third phosphate group.
• The chemical bond breaks between the adenine and ribose units.
• The chemical bond breaks between the ribose unit and the first phosphate group.
• The chemical bond breaks between the second and third phosphate groups.

Which statement best describes the relationship between adenosine diphosphate (ADP) and adenosine triphosphate (ATP)?

• With an input of energy, ADP rearranges to become ATP.
• Without any energy change, ADP rearranges to become ATP.
• With an input of energy, ADP combines with a phosphate group to become ATP.
• With a release of energy, ADP combines with a phosphate group to become ATP. _______

Chloe is developing a model of photosynthesis. The first part of the model is shown below. Which would be the MOST useful next step for Chloe to develop the photosynthesis model further?

• Extend the lines for sunlight so that they pass through the autotroph.
• Represent a chemical reaction in the autotroph that produces high-energy carbohydrates.
• Represent a chemical reaction in the autotroph that produces high-energy proteins.
• Draw a circle to represent a heterotroph, and draw a line to connect it to the autotroph. _______

A mushroom gains its energy by decomposing the tissues of dead organisms. Should mushrooms be classified as autotrophs, heterotrophs, in both groups, or in neither group, and for what reason?

• They are autotrophs because they do not eat their food, as animals do.
• They are autotrophs because decomposition is very similar to photosynthesis.
• They are heterotrophs because their food is made by other organisms.
• They are both autotrophs and heterotrophs, because they may grow in sunlight or darkness. _______

Neurons are cells of the nervous system. As part of its normal function, a neuron pumps sodium ions (Na + ) out of the cell and potassium ions (K + ) into the cell. Which statement describes the role of energy in this process?

• The process releases energy that is used to make ATP.
• The process releases energy in the form of heat.
• The process requires energy that is provided by the sodium and potassium ions.
• The process requires energy that is provided by ATP.

What is the primary function of ATP in cells?

• Breaking down glucose molecules
• Storing and releasing energy
• Producing carbon dioxide
• Converting light to heat

Adenosine triphosphate (ATP) consists of which components?

• Adenine and two phosphate groups
• Ribose and four phosphate groups
• Adenine, ribose, and three phosphate groups
• Glucose and three phosphate groups

When does a cell store energy in the form of ATP?

• Only during photosynthesis
• During periods of rest
• When phosphate groups are removed
• When energy is available to add phosphate to ADP

What is the main difference between ATP and ADP?

• The type of sugar present
• The number of adenine molecules
• The presence of ribose
• The number of phosphate groups

Energy is released from ATP when:

• A fourth phosphate group is added
• The molecule completely breaks down
• The third phosphate group splits off
• Adenine separates from ribose
