Gibberellins affect many processes in plants. In seeds embryos, gibberellins are believed to signal hydrolysis of the stored food reserves through inducing the synthesis of the enzyme a-amylase. Which food source are gibberellins targeting with the release of a-amylase?
A. omega-3 fatty acids
B. starch
C. glycogen
D. fructose
E. protein

Clarify Question
· What is the key concept addressed by the question?
o This question is asking about the function of amylase.
· What type of thinking is required?
o You are being asked to take what you already know and apply it to the use of amylase.
· What key words does the question contain and what do they mean?
o Gibberellin, which is a plant hormone.
o Hydrolysis, which refers to the splitting of larger molecules into smaller molecules.
o Amylase, which an enzyme that occurs in plants.

· What do you already know about hormone and enzyme function in plants? How does it relate to the question?
o Gibberellins have multiple roles within plants.
o Amylase, is an enzyme that breaks down starch into individual glucose molecules.
Consider Possibilities
· What other information is related to the question? Which information is most useful?
o Amyl/o- is a word root that refers to starch, not other macromolecules.
Choose Answer
· Given what you now know, what information and/or problem solving approach is most likely to produce the correct answer?
o The key in this question is the reference to amylase. Amylase is an enzyme that is found in plants and other organisms, and it is used to break down starch.
Reflect on Process
· Did your problem-solving process lead you to the correct answer? If not, where did the process break down or lead you astray? How can you revise your approach to produce a more desirable result?
· Apply level:
o This question asked you to understand the role of amylase. Answering this question correctly depended on your ability to use the function of amylase in a new situation. If you got the correct answer, great job! If you got an incorrect answer, where did the process break down? Did you remember that amyl/o is always a reference to starch, or that amylase is an enzyme that hydrolyzes starch? Did you have trouble extending the function of amylase to determine the correct answer?
