What is metabolism?
The sum of all chemical reactions that occur within an organism.
What are the two main classes of metabolism?
What is catabolism?
Reactions that generate energy by breaking down complex organic compounds.
What is an example of catabolism?
Proteins are broken down into amino acids, releasing energy.
What is anabolism?
Reactions that require energy to build complex organic molecules from simpler ones.
What is an example of anabolism?
Amino acids are used to build proteins, consuming energy.
What stores energy in cells?
Adenosine triphosphate (ATP).
How is energy released from ATP?
By breaking the high-energy bonds between phosphate groups.
What is the equation for the breakdown of ATP?
ATP → ADP + Pi
What is the equation for the breakdown of ADP?
ADP → AMP + Pi
What are oxidation and reduction?
Oxidation is the loss of an electron; reduction is the gain of an electron.
What does LEO says GER mean?
Lose Electrons = Oxidation, Gain Electrons = Reduction.
What is a redox reaction?
A reaction where oxidation and reduction occur simultaneously.
What is anabolism?
Reactions that require energy to build complex organic molecules from simpler ones.
What are oxidation and reduction?
Oxidation is the loss of an electron; reduction is the gain of an electron.
