A |
|---|
Activation energythe minimum amount of energy that chemical reactants must absorb to start a reaction | |
Aerobic cellular respirationa process that uses oxygen to harvest energy from organic compounds | |
Anabolic pathwaya pathway in which energy is supplied to build complex molecules from simple molecules | |
Anaerobic respirationa process that uses a final inorganic oxidizing agent other than oxygen to produce energy | |
Andenosine triphosphate (ATP)energy that powers nearly every cellular function; consists of 3 parts: a nitrogenous base (adenine), a five-carbon sugar (ribose), and a chain of 3 phosphate groups.
| |
ATP cyclethe cyclic and ongoing breakdown and re-synthesis of ATP | |
B |
|---|
Bond energythe minimum amount of energy that is required to break a particular type of bond; measured in kJ/mol of bonds | |
C |
|---|
Catabolic pathwaya pathway in which energy is released and complex molecules are broken down into simple molecules | |
Citric acid cyclea cyclic series of reactions that transfers energy from organic molecules to ATP, NADH, and \( FADH_2 \) and releases carbon atoms as \(CO_2\) | |
D |
