FRQ Test Question for HSPE Week

Explain how a hypothetical extracellular signal (like a hormone) can result in a cellular response. Your answer must include knowledge of 1) cell membrane receptor, 2) signal transduction in cell, 3) gene activiation, and 4) gene product. No specific example of a signal is required. It would help to review sections 5.5, 5.6, have knowledge of chapter 10, and parts of chapter 11. Each section, 1-4, is worth a maximum of 5 points and 20 points total. Grade reported as percent scored.

Here are some inks to DNA animations I have used in class.
