Question 8 was written to the following Learning Objectives in the AP Biology Curriculum Framework: 3.22 and 3.23. Overview Question 8 asks students to use a model of a hormone-signaling pathway to explain how extracellular signals are converted to specific cellular responses. Students were presented with a visual representation.

Endocrine signaling involves release of a chemical hormone that enters the bloodstream and signals cells elsewhere in the body. Autocrine signaling involves a cell releasing a molecule that binds to receptors on its own surface; therefore, in autocrine signaling the signaling cell and the target cell are the same.
Receptors are generally trans-membrane proteins which bind to signaling molecules outside the cell. Subsequently, they transmit signals through a sequence of molecular switches to internal signaling pathways. Membrane receptors fall into three major classes: G-protein-coupled receptors, ion channel receptors, and enzyme-linked receptors.

AP Biology Stahl Notes 3 d. Roles of Membrane Proteins: i. Transport- allowing solutes to pass through, transport ATP (through channel and carrier proteins) ii. Enzymatic Activity- a protein built into the membrane may be an enzyme with an active site that binds to a specific substrate to create a desired or.
The activity, “Dealing Signals,” can help students understand signaling pathways asks them to act as the components of a signaling pathway by taking cues from cell communication cards. Students mimic signaling pathways by running in place, interacting with specific classmates by either bumping into them or holding them, and leaning or lifting arms to simulate conformational changes.

Cell-cell recognition involves direct contact between cells. Synaptic signaling requires the nerve cell to be very close to the target cell. Plasmodesmata in plant cells is a junction that allows molecules to pass between adjacent cells with out having to cross the plasma membrane. Hormones are used by plants and animals for long-distance.

Cell signaling allows bacteria to respond to environmental cues, such as nutrient levels and quorum sensing (cell density). Yeasts are eukaryotes (fungi), and the components and processes found in yeast signals are similar to those of cell-surface receptor signals in multicellular organisms.
