Campbell Biology Chapter 8 | Questions and Answers with complete solution

metabolism - the totality of an organism's chemical reactions metabolic pathway - a series of chemical reactions that begins with a specific molecule, which is then altered in a series of steps catalyzed by specific enzymes, resulting in a certain product catabolic pathway (breakdown pathway) - metabolic pathway that releases energy by breaking down complex molecules into smaller, simpler compounds ex/ cellular respiration (organic fuels break down to CO₂ and water) anabolic pathway (biosynthetic pathways) - metabolic pathway that consumes energy to build complex molecules from simpler ones ex/ protein from amino acids bioenergetics - the study of how energy flows through living organisms energy - the capacity to cause change; exists in various forms, some perform work; the ability to rearrange a collection of matter kinetic energy - energy associated with motion heat (thermal energy) - kinetic energy associated with the random movement of atoms or molecules potential energy - energy that matter possesses because of its location or structure chemical energy - the potential energy available for release in a chemical reaction due to the molecule's structure thermodynamics - the study of energy transformations
