Rio Salado CHM 130 Midterm Objectives with Complete Solutions What is the definition of an element in chemistry? An element is a pure substance consisting of only one type of atom. How is a compound different from a mixture? A compound is a substance composed of two or more different elements chemically combined, while a mixture is a combination of two or more substances that are not chemically bonded. What does the term “molarity” refer to in chemistry? Molarity refers t...

The autonomic Nervous System is divided in two branches what are they? - 1. PNS= Parasympathetic Nervous System / 2. SNS = Sympathetic Nervous System A person can experience 70% reduction peripheral vision during the activation of sympathetic nervous system. True or False - True What concept between heart rate and performance which examines the optimal heart rate zone for optimal performance? - Inverted-U Law What is the optimal performance heart rate? - 115 to 145 BPM What are the food t...

dependent upon the overall order of the reaction The units for a rate constant, k, are: dependent upon the overall order of the reaction a rate constant is unitless M^-1 M^-1 s^-1 s^-1 the fraction of collisions with total kinetic energy greater than Ea increases. An increase in the temperature of the reactants causes an increase in the rate of reaction. The best explanation for this behavior is that as the temperature increases, the collision frequency increases. the fraction of coll...

Ras signaling - GTPase - promotes growth and proliferation - mutated in 20-30% of all cancers - point mutations are most common G12V mutation - blocks GAP binding - locks RAS in active state, promoting proliferation Q61K mutation - raises activation energy of GTP hydrolysis - blocking hydrolysis, keeping RAS active Hallmarks of cancer 1) self-sufficiency in growth signals 2) insensitivity to anti-growth signals 3) unstable DNA 4) metastasis 5) evasion of apoptos...

activation energy energy needed to get a reaction started Delta G (change in G - change in free energy) respresented in a reaction coordinate diagram. Positive is thermodynamically unfavorable. Negative is thermodynamically favorable (exergonic - release energy). = G(products) - G(reactants) enzyme catalyze chemical reaction. Lower activation energy. Biological catalyst (protein) enzyme inhibition results in decrease in activity of that enzyme, reaising activation enregy...
