BIO310H5 Study Guide - Midterm Guide: Active Transport, Axon Hillock, Cervical Vertebrae
Document Summary
Last 4 slides on lecture 6 are not on the test. Total will be 60 points then recalculated: non-polar are inside the lipid bilayer. Molecule should break all of its hydrogen bond in order to pass the bilayer: secondary active transport there is no direct energy required. These soma are connected with dendrites and axons: types of neurotransmitters and an example of each. No, the only voltage-gated are in the axon hillock/ spike initiation zone: soma itself has nothing to do with the ap. Graded potential will reach the spike-initiating zone: excitatory and inhibitory. Negative and positive feedback; negative feedback is used for homeostasis give examples. Using the nt ach, describe fast vs. slow chemical nt. Thermoregulators there is a zone of stability. At environmental extremes, internal conditions cannot be controlled. Major homeostatic control systems nervous and endocrine systems. Passive (high to low [] gradient) or active (against [] gradient, needs atp) Passive transport/ facilitated diffusion requires: channels.
