How living systems respond to stresses, like exercise, heat, or high altitude - Homeostasis Describes the compensatory processes by which the body functioned to limit variations in the internal environment - Homeostasis Body Temp, BP, Blood glucose concentration, Blood gas concentration - Homeostatically Regulated Parameters the value you want to maintain - Set Point Sensor, Integrator, and Effector - Negative Feedback Loop Tangible Components The part of the body that can sense/detect the regulated variable - Sensor The part of the body that can interpret information coming from the sensor, & send messages out to the effector - Integrator The part of the body that can affect/change the regulated variable - Effector Set Point, Threshold, Error Signal - Conceptual Components of Negative Feedback Loop Temperature you want to maintain - Set Point The difference where the integrator decides if the difference between the actual value and set point is too large. - Threshold Deviation between the actual value of a variable and the set point value - Error SignalSet Point temperature in the body - 37 Degrees Celsius Nutrient and oxygen use, waste production, and heat production - Exercise increases what rates A parameter is constant over a period of time. - Steady State Adenine, Ribose, Triphosphate - What are the 3 parts of ATP made up of carbon, hydrogen, & nitrogen atoms - Adenine sugar molecule - Ribose linked in a chain attached to ribose - Triphosphate Made of carbon, hydrogen, and oxygen - Carbohydrates simplest sugar; ex. glucose - Monosaccharide Sucrose; ex. sugar packet - Disaccharide Combination of glucose and fructose - Disaccharide Lactose; sugar in milk - Disaccharide 3 or more sugars - Polysaccharide Plants storage form of carbohydrate polysaccharide - StarchAnimals storage form of carbohydrate polysaccharide - Glycogen made of carbon and hydrogen atoms - Fat
