HOME UNIT- AP BIO: Cell CommunicationFocus on the type and level of information in CliffNotes, but use your textbooks (full of fabulous images) to fully understand that information.CliffNotes Chapter 6Biology Concepts and Connections: p. 68, 220, 518-519, 588Biology (Raven, Johnson et al.): Chapter 9TEST- open note (your handwritten notes only, no scans or xeroxes) Remember you need to understand the information and THEN take your notes. Don’t just copy info onto your paper that you do not understand because you can’t answer questions on the test without a level of understanding. (No test corrections)How do cells receive signals from other cells? There are 4 major ways. Be able to distinguish between them.What is a signal transduction pathway?What is the difference between a membrane receptor and an intracellular receptor?An example of a signal transduction pathway used to trigger the release of glucose from cells in the liver. is meant by a conformational change?What is a signaling cascades?Understand and be able to explain a Kinase cascade (phosphorylation cascade)Name of enzyme that removes phosphate group?G-Protein- Coupled Receptors (You will need to watch these several times!) ’s a ligand? What is GTP and GDP? What is their function?What are some of the things that activation of a G Protein-Couple Receptor causes to happen in the cell?What is a gated ion receptor?Example of a gated ion receptor is that seen in a neuron that is involved in transmitting nerve impulses.Neuron Animations: Be able to explain how a nerve impulse is produced and how one nerve (neuron) signals another.Protein Kinase Receptors signal transduction is an example of this type of cell signaling. Explain.What’s a dimer?How is the transduction pathway started?What’s the difference between a G Protein-Coupled Receptor and a Protein Kinase Receptor?The receptors we have been working with are found in the cell membrane.Where in the cell do you find intracellular receptors?Explain how steroid hormones activate cell activities.If cell signaling pathways do not operate properly, disease can result.Explain the cellular basis for the disease Cholera.Explain the cellular basis for cancer.
