What is work? What is energy? What are the two laws of thermodynamics? What part does heat play in the cell's energy transformations?
|
Work: any change in the state or movement (motion) of matter (changing the states of matter)
Energy: Laws of thermodynamics: law of conservation of energy and law of increasing entropy Cell's do NOT use heat. They are isothermal |
|
|
what is the relationship between anabolic and catabolic reactions? between endergonic and exergonic?
|
anabolic is building up reactions (requires energy) catabolic is breaking down (releasing energy)
endergonic reactions are anabolic where exergonic are catabolic |
|
|
what is ATP? Why is ATP important? what is the relationship between ATP and ADP? how can one be transformed into the other? why must a cell always have a constant supply of ATP?
|
adenosine triphosphate;it is an energy carrier.
|
|
|
what are cofactors? what are coenzymes?
|
Cofactors: metallic ions
Coenzymes: organic cofactors such as vitamins.. |
|
|
Explain how temp. and pH affect enzyme activity
|
extreme temps or pH can denature them. Basically perm. alter it's shape. Shape changes, it stops working
