What are the two types of chemical reactions?
either release energy or they require an input of energy and store energy
What is an exergonic reaction?
a chemical reaction that releases energy,
What does an exergonic reaction begin with?
with reactants whose covalent bonds contain more energy than those in the products
What is an example of an exergonic reaction?
What is cellular respiration?
a chemical process that uses oxygen to convert the chemical energy stored in fuel molecules to a form of chemical energy that the cell can use to perform work
What do endergonic reactions yeild?
yield products that are rich in potential energy
what kind of process do cells use?
What is metabolism?
the total of an organism's chemical reactions
What is a metabolic pathway?
a series of chemical reactions that either builds a complex molecule or breaks down a complex molecule into simpler compounds
What is energy coupling?
the use of energy released from exergonic reactions to drive essential endergonic reactions
Chemical reactions either release or store energy
