It is important for cells to degrade misfolded proteins.If misfolded proteins are not degraded,the misfolded proteins may
A) waste excessive ATP in attempts to refold them.
B) aggregate and interfere with normal cellular function.
C) eventually refold, but not until excessive and sometimes fatal levels of cellular energy are spent.
D) be excreted from the cell rather than recycled for building blocks.

Question

Quizplus · Accepted Answer

Misfolded proteins can aggregate and interfere with normal cellular function if they are not degraded. This can lead to diseases such as Alzheimer's and Parkinson's. Wasting excessive ATP in attempts to refold them (A) and spending excessive and sometimes fatal levels of cellular energy to refold them (C) are also possible consequences, but the primary concern is the interference with cellular function. Excreting the misfolded proteins from the cell (D) is not a viable option as it does not address the underlying issue of misfolded proteins and can lead to a loss of important building blocks for the cell.
