How does the cell overcome inhibition from irreversible inhibitors?

a. by binding a second inhibitor, which forces the enzyme's conformation to dislodge the first inhibitor b. by phosphorylating the enzyme, altering the enzyme's conformation to dislodge the inhibitor c. by altering the cellular pH, which will decrease the bonding between the enzyme and the inhibitor d. by degrading the enzyme-inhibitor complex and generating new enzyme e. by upregulating the expression of other enzymes with similar catalytic functions

Unattached earlobes (EE or Ee) are described in the textbook as dominant over attached earlobes (ee). A couple both have unattached earlobes. Both notice that one of their parents on both sides has attached earlobes (ee). Therefore, they correctly assume that they are carriers for attached earlobes (Ee). The couple proceeds to have four children.

A. The children must repeat the grandparents' genotype (Ee). B. If the first three are heterozygous, the fourth must be homozygous recessive. C. Two heterozygous, one homozygous recessive, and one homozygous dominant is a likely outcome, but all heterozygous, or two, three, or all four homozygous are also possible. D. They can be certain that three will be heterozygous and one homozygous recessive. E. All children must have unattached earlobes since both parents possess the dominant gene for it.
