A biologist working in a lab adds a compound to a solution that contains an enzyme and substrate. This particular compound binds
reversibly to the enzyme at the active site. Once the compound is bound to the enzyme, the catalysis of substrate to product stops. Which of the statements is true of the compound? a. The compound is a catalyst for the reaction. b. The effect of the compound cannot be overcome by adding more substrate. c. The compound is an allosteric inhibitor. d. The effect of the compound can be overcome by adding more substrate. e. The compound is an allosteric activator.
The correct answer is C) The compound is an allosteric inhibitor.
Explanation:
An inhibitor works in many ways, but this particular one binds to the allosteric site in the enzyme causing a decrease of the enzymatic activity. When this situation happens, the inhibitor doesn't bind to the active site, but it changes the enzyme's shape so it cannot work properly anymore.
Lithosphere is the final layer on the planet Earth, erosion caused by wind (atmosphere) or rain (hydrosphere) may also wear down rocks in the lithosphere.
Since both parents (green and yellow) are homozygous and green is dominant, when they are crossed all the resultant offsprings will have both genes of green and yellow in their genotype but will appear as green( phenotype) because the green colour is dominant and has masked the yellow colour which is recessive.
