AP Biology Study Guide Chapter 11 1. Categorize chemical signals in terms of the proximity of the communicating cells. Local signaling – a. Paracrine signaling – a secreting cell acts on nearby target cells by discharging molecules of a local regulator (a growth factor‚ for example) into the extracellular fluid. b. Synaptic signaling – a nerve cell releases neurotransmitter molecules into a synapse‚ stimulating the target cell. Long distance signaling- c. Hormonal signaling – specialized

Biology Revision Notes Biochemical Tests: Proteins - add biurettes reagent to the sample. If protein is present‚ clear colour change from blue to purple. Reducing Sugars – add Benedict’s reagent to the sample. Heat in Bunsen or water bath. If reducing sugars are present‚ clear colour changes from blue -> orange red precipitate. Lipids – dissolve sample in ethanol. Slowly pour the solution into the water slowly. If lipids are present a white emulation forms on the surface. Starch – add iodine

Biology - Main Questions And Answers: Complete the table with a tick if the statement in the first column is true‚ for each process. Write a simple equation to show how ATP is synthesised from ADP: ADP + Pi ATP Give two ways in which the properties of ATP make it a suitable source of energy in biological processes: 1. Energy released in small/suitable amounts 2. Soluble 3. Involves a single/simple reaction Humans synthesise more than their body mass of ATP each day.

Section 1 : Identifying the Genetic Material Griffith’s Experiments In 1928‚ Frederick Griffith‚ a bacteriologist‚ was trying to prepare a vaccine against pneumonia. A vaccine is a substance that is prepared from killed or weakened disease-causing agents‚ including certain bacteria. The vaccine is introduced into the body to protect the body against future infections by the disease-causing agent. Griffith discovered that harmless bacteria could turn virulent when mixed with bacteria that cause
