Question

Quizplus · Accepted Answer

Ricin is a protein toxin that works by preventing protein synthesis in human cells. It does this by inactivating the ribosomes in the cell, which are responsible for synthesizing proteins. Without functional ribosomes, the cell cannot produce the proteins it needs to survive, leading to cell death. The other options listed are not accurate descriptions of how ricin affects human cells.
