Allosteric enzymes a. ? have regions that bind with inhibitor or activator molecules b. have a broader range of working conditions? c. ? are not affected by temperature or ph d. ? have two active sites e. ? are associated with important energy-carrying nucleotides

Allosteric enzymes HAVE REGIONS THAT BIND WITH INHIBITOR OR ACTIVATOR MOLECULE. Allosteric enzymes have two binding site: the active site and the allosteric site, where effectors molecules are bind. Allosteric enzymes are regulatory enzymes which change their conformations depending on the type of molecule that is bind to their allosteric sites. There are two types of effector molecules that can bind to the allosteric site: they are inhibitors and activators. Inhibitors bind to the allosteric site of the enzyme in order to prevent the enzyme from functioning while activators modified the enzyme to function.

They both have rock surfaces

Humans can affect weathering and erosion in several ways.  humans cause  increases in acid rain and pollution, which increase the amount of  weathering  agents in the air and water, and then on land.for an easy answer: 1) acid rain2) pollution
