metabolism definition
the totality of an organism’s chemical reactions
metabolic pathway
begins with a specific molecule that is altered in steps to result in a specific product
where each step is catalyzed by an enzyme
catabolic pathways
release energy by breaking down complex molecules
cellular respiration
catabolic pathway
-sugars and stuff are broken down to CO2 and H2O
anabolic pathways
consume energy to build complicated molecules from simple ones
AKA biosynthetic pathways
biosynthetic pathways
anabolic pathway
synthesis of proteins
anabolic pathway
-amino acids build up proteins
bioenergetics
how energy flows through living organisms
