a reaction
d. Classify photosynthesis and cellular respiration as the appropriate type of
reaction
3. Describe ADP and ATP in terms of structure and function

from a graph showing energy change over a course of a reaction
a. Reactants and products
b. Activation energy with enzyme
c. Activation energy without enzyme

6. Describe 4 parts of food processing
7. Name the products produced when each of the following is digested: proteins,
fats, polysaccharides, disaccharides, nucleic acids
8. Describe the function of the crop and gizzard. Give examples of animals that have
this
9. Explain how a gastrovascular cavity is different from an alimentary canal

microvilli)
14.Be able to recognize the following structures from a diagram: salivary glands,
pharynx, oral cavity, esophagus, stomach, duodenum, small intestine, liver, gall
bladder, large intestine, pancreas
15.Be able to state the type of digestion (mechanical, chemical, or none) in the
structures from #14
