KNES 2160 Study Guide - Midterm Guide: Electrochemical Gradient, Ion Channel, Fluid Compartments
Document Summary
Mostly muscle phyiology, more than 50%, look at the basics for the rest, mostly multiple choice, no short answers and matching. Themes in physiology: structure and function are closely related, living organisms need energy. Information flow coordinates body functions: homeostasis maintains internal stability. Types of nucleiotides: ribonucleotide, deoxyribonucleotide, adenine, guanne, thymne, uracil, cutosine. Homeostatsis is the interaction between outside world, extracellular fluid and intracellular fluid: keep near set point/optimum value. Intrinsic (autoregulation) regulation (automatic response in cell: extrinsic regulation (controlled by nervous and endocrine system) Response loop: stimulus sensor input signal integrating center output signal target response. Study guide human phys midterm: negative feedback stabilizes variable. Brought back to homeostasis (body temp, bp, bg: positive feedback reinforces stimulus. Self-terminating (clotting: feedforward control anticipates change (saliva) Proteins: enzymes: speed up reaction, membrane transporters: move substances across cell membrane, signal molecules: act as hormones, receptors: usually found on cell membranes, bind signal molecules, binding proteins: acts as transports in blood.
