Besides turning enzymes on or off, what other means does a cell use to
control enzymatic activity?
a)compartmentalization of enzymes into defined organelles
b)exporting enzymes out of the cell
c)connecting enzymes into large aggregates
d)hydrophobic interactions
e)cessation of all enzyme formation

Option A and option C are both plausible answers, although option A is phrased to be the more likely answer, if there is only one answer to this question.

Explanation:

Compartmentalisation of enzymes can be observed in fatty acids synthesis vs fatty acid metabolism in the liver. Similarly, enzymes are often connected together in a larger protein structure to allow simultaneous control of all the enzymes such as in fatty acid synthesis in liver cells, where enzymes are all part of fatty acid synthase.

answer; i believe that the correct answer is (lung);

an organism's phenotype is the  form of a trait  that it  displays. for  flowercolor, a pea  plant  can  display  a phenotype of purple or white flowers. an organism's  genotype  is the alleles of a gene it contains. based on his data, mendel concluded that a phenotype can be  determined  by more than one  genotype.
