Ch 6 pt 1 Flashcards
Metabolism
The totality of an organism’s chemical reactions.
Metabolic pathways
Begins with a specific molecule and ends with a product
Catabolic pathways
release energy by breaking down complex molecules into simpler compounds
Cellular respiration
the breakdown of glucose in the presence of oxygen
Anabolic pathways
consume energy to build complex molecules from simpler ones
Anabolism
The synthesis of protein from amino acids
Bioenergetics
the study of how organisms manage their energy resources
Energy
the capacity to cause change
Heat (thermal energy)
kinetic energy associated with random movement of atoms or molecules
Potential energy
energy that matter possesses because of its location or structure
