Use the following information to answer the next three questions. One job of the cells lining the small intestine may be to make digestive enzymes. These enzymes are proteins that are made inside the cells and then moved out of the cell into the intestine to digest the food we eat. 3. The synthesis of molecules inside cells requires chemical energy in the form of ATP, most

of which is produced by the

A. nucleus B. chloroplasts C. mitochondria D. cell membrane

4. Once enzymes are produced, they have to be transported through the cell. The part of the

cell that serves as a transport system is the

A. endoplasmic reticulum B. cell membrane C. mitochondria D. nucleus

Use the following additional information to answer the next question. Once the enzymes are collected into vacuoles, the vacuoles are moved to the cell membrane. The vacuole membrane fuses with the cell membrane, releasing the enzymes into the intestine.

_____ 6. osmosis (e) molecules move against their concentration gradient, which requires energy (ATP) _____ 7. active transport (f) the membrane pinches off to enclose particles

and take them into the cell to be digested or used by the cell

Use the following information to answer the next question. Oxalis is a common forest plant in southeastern Canada and the eastern United States. It has the unusual ability to alter its leaves from horizontal to vertical position in response to intensity of sunlight.

Transpiration rates were measured as weight loss from leaves.
