|
Bioenergetics
|
The flow of energy in a biological system, concerned primarily with the conversion of macronutrients
|
|
Macronutrients
|
Carbohydrates, protien, and fats
|
|
Energy
|
The ability or capticity to perform work
|
|
Catabolism
|
The breakdown of large molecules, associated with the release of energy
|
|
Anabolism
|
The syntheses of larger molecules from smaller molecules can be accomplished using the energy released from catabolic reactions
|
|
Exergonic reactions
|
Energy release reactions that are generaly catabolic
|
|
Endergonic reactions
|
Require energy and include anabolism processes and the contraction of muscle
|
|
Adenosine triphosphate
|
Allows the tranfer of energy from exergonic to endergonic reactions. makes muscle activity and growth possible
|
|
Hydrolysis
|
The breakdown of atp to yeild energy
|
|
Phosphagen system
|
Provides atp primarily for short-term, high-intensity activities, and is active at the start of exerices regardless of the intensity
|
|
Law of mass action
|
States that the concentrations of reactants or products in solution will drive the direction of the reactions
|
|
Near-equilibrium reactions
|
?
|
|
Glycolysis
|
The breakdown of carbohydrates
|
|
Pyruvate
|
The end result of glycolysis
|
|
Directions that pyruate can take
|
Pyruate can be converted to lactate
pyuate can be shuttled into the mitochondria
|
