Essentially, the first law of thermodynamics says that
|
Energy can be neither created nor destroyed
|
The second law of thermodynamics states that
|
Energy tends to become increasingly more disorganized
|
A molecule that gives up an electron becomes
|
Both ionized and oxidized
|
In simple diffusion
|
A. the rate of movement of molecules is controlled by temperature and pressure.
b. the movement of individual molecules is random. c. the movement of molecules of one substance is independent of the movement of any other substance. d. the net movement is away from the region of highest concentration. e. all of these |
The formation of large molecules from small repeating units is known as what kind of reaction?
|
Condensation
|
Hydrolysis is a (an) _____ reaction.
|
Cleavage
|
Although it its too simple an explanation, the concept of a key fitting into a lock is descriptive of the
|
Matching of enzyme with substrate
|
During enzyme-catalyzed reactions, substrate is a synonym for
|
Reactants
|
Enzymes
|
A. are very specific.
b. act as catalysts. c. are organic molecules. d. have special shapes that control their activities. e. all of these |
Enzymes increase the rate of a given reaction by lowering what kind of energy?
|
Activation
|
Allosteric inhibition is generally a result of
|
Binding regulatory molecules to another site
|
The basic functional unit of the mammalian kidney filters the blood and actively secretes and resorbs specific solute molecules. What is the name of this unit?
|
Nephron
|
In the nephron, the glomerulus filters blood, after which the filtrate - water and solutes - enters Bowman/s capsule. From Bowman's capsule, the filtrate passes through several regions of a long tubule. Out of which region are most of the solutes and water removed from the tubule?
|
Proximal convoluted tubule
|
Does the loop of henle concentrate urine?
|
No
