What is an allosteric site?
a) the site on an enzyme where the substrate binds
b) the active part of a non-competitive inhibitor of an enzyme reaction
c) the area on an enzyme that binds the end-product of a metabolic pathway
d) the area on a competitor molecule that inhibits an enzyme reaction

The correct answer is C the area on an enzyme that binds the end product of a metabolic pathway.

Explanation:

Some enzymes contain an additional site beside an active site.The additional site is known as allosteric site.

    The allosteric site act as a binding site of many regulatory compounds called mediator which may be either activator or inhibitor according to action they generates after interacting with the target enzyme.

  The high level end product of some metabolic pathway binds to the allosteric site of the regulatory enzyme that controls the committed step of that pathway thereby blocking that pathway.

1. (1.2kw)x(15/60hours) = .3kwh --> a

2. (5kw)x(90/60hours)x(8cents/kwh) = $0.60 --> d

3. microwave --> 1200 watts = (1.2kw)x(6/60hours) = .12kwh

coffee-maker --> 900 watts = (.9kw)x(10/60hours) = .15kwh

therefore, it requires more energy for the coffee-maker to do the same amount of work.

so the answer is a.
