How long did it take for half of the radioactive Protein X to be lost from the cell after radioactivity began to decline?

• A. 100 seconds
• B. 200 seconds
• C. 300 seconds
• D. 500 seconds

Answer: (A)

To determine how long it takes for half of the radioactive Protein X to be lost from the cell after radioactivity begins to decline, we need to refer to the concept of half-life. The half-life is the time required for half of the substance to be eliminated or to decay. If the correct answer indicates that it takes 100 seconds for half of Protein X to be lost, this means that after 100 seconds, the radioactivity would decrease to half of its original amount. This is a fundamental principle in the study of radioactive decay and relates to various biological processes, especially in the context of how cells utilize and eliminate substances. In practice, if we consider the time from radioactivity beginning to decline, using this half-life concept, after the 100 seconds, the original amount of Protein X would be reduced significantly, demonstrating the exponential decay characteristic of radioactive substances. Subsequent measurements taken after additional time would display further reductions consistent with this half-life of 100 seconds, where another 100 seconds would reduce the remaining amount to half of that again, and so forth.
