, Bioengernetics
How energy flows through organisms.
ATP
Used for mechanical, transport, and chemical work. ATP is also an RNA nucleotide.
Mechanical Work
Energy used in motor proteins and muscle cells during contractions.
Transport Work
Energy used to move substances against their gradient.
Chemical Work
Energy used to convey polymers into monomers.
Gibs Free Energy
Portion of a systems energy that can preform work when temperature and pressure are
uniform throughout the system.
Exergonic Reactions
Delta G is less than zero (-) and the reaction is spontaneous. Example- ATP hydrolysis.
Endergonic Reactions
Delta G is greater than zero (+) and the reaction is non-spontaneous.
Enzymes
Lower energy barriers and can be denatured by temperature.
