What is metabolism in living organisms?
The sum of all chemical reactions converting reactants into products.
Metabolism definition
Sum of all chemical reactions in organisms.
What type of energy change characterizes anabolic reactions?
They are endergonic, requiring energy.
Anabolic reactions
Require energy; build macromolecules.
Which forms of energy are important to living organisms?
Kinetic, potential, thermal, and chemical energy.
Catabolic reactions
Release energy; break down substrates.
What is ATP in cellular energy use?
The energy currency used in cells.
Energy currency
ATP in cells.
