Propose a Valid Reason to Explain Why Is It Critical

question 44

Multiple Choice

Propose a valid reason to explain why is it critical that the K⁺ channel activation gate responds slightly slower to depolarization than the Na⁺ channel activation gate.

• A)If both gates showed identical response times,movements of Na⁺ and K⁺ ions would cancel out each other's effects on membrane potential changes.
• B)If both gates showed identical response times,movements of Na⁺ and K⁺ ions would magnify each other's effects on membrane potential changes,creating dangerously large action potentials.
• C)It is not critical and there would be no change in action potential characteristics if this difference in response time did not exist.
• D)The conformational change in one gate is necessary to trigger the activation of the other.

Epistasis

Condition in which certain alleles of one locus alter the expression of alleles of a different locus.

Alleles

Different forms of a gene that arise by mutation and are found at the same place on a chromosome.

Gene Interaction

The ways in which different genes influence each other's expression, often leading to complex traits or outcomes in an organism.

Calico Cats

Cats characterized by a tri-color fur pattern, typically involving patches of orange, black, and white, this pattern is most commonly found in female cats due to genetic linkage to the X chromosome.
