Vapor Pressure is a form of Dynamic Equilibrium Molecules are constantly moving between phases, but the rate at which the molecules move from the liquid ↔ gas phase is constant Chemical Equilibrium a state in which the rate of a forward reaction and the rate of the reverse reaction are the same as the reaction uses its reactants the forward reaction starts to slow down How is chemical equilibrium reached? reactants and products are still forming when it is reached, just at th...

4 concepts of Dalton's atomic theory and their correctness - 1. All matter is composed of indivisible particles (atoms) (can split atoms but this is generally correct) 2. atoms and indestructible and unchangeable (can change with extraneous outside methods, but still true) 3. all atoms of a given element are identical (false because of isotopes) 4. compounds are formed when atoms of different elements combine (true) absolute numbers - counts rather than measurements, conversion factors; i...

Catalyst - 1. Chemical or biological substance or structure that lowers activation energy 2. Accelerates the rate of a chemical rxn Enzymes - Biological catalysts that are capable of performing multiple rxns (are recycled). They can be proteins or RNA, are faster than chemical catalysts, and act under mild conditions (bodily temperature/pressure). They are highly specific and tightly regulated. Enzyme functions - - cell shape and motility - surface receptors - metabolism - cell cycling ...

BIO 441A EXAM 3 STUDY GUIDE WITH COMPLETE SOLUTION. LECTURE ONE - METABOLISM INTRODUCTION ● Autotrophs synthesize all their own cellular constituents from simple molecules ● Heterotrophs obtain energy through oxidation of organic compounds and therefore rely on autotrophs ● Metabolism involves many reactions such as ○ Glycolysis/gluconeogenesis ○ The citric acid cycle ○ Oxidative phosphorylation ● Catabolism is the degradation of biomolecules ○ Energy rich nutrients are...
