The most immediate result of destruction of a cell's ribosomes would be:
A
the breakdown of the nuclear envelope
B
a decrease in protein synthesis
C
an increase in ATP production
D
an accumulation of lipids in the cell
Verified step by step guidance1
Understand the function of ribosomes: Ribosomes are cellular structures responsible for synthesizing proteins by translating messenger RNA (mRNA) into polypeptide chains.
Consider the impact of ribosome destruction: If ribosomes are destroyed, the cell loses its ability to produce proteins, which are essential for various cellular functions, including enzyme activity, structural support, and signaling.
Eliminate unrelated options: The breakdown of the nuclear envelope is not directly related to ribosome function. Similarly, an increase in ATP production or lipid accumulation does not directly result from ribosome destruction.
Focus on protein synthesis: Since ribosomes are directly involved in protein synthesis, their destruction would lead to a decrease in protein production, affecting the cell's ability to perform essential functions.
Conclude the most immediate result: The most immediate consequence of ribosome destruction is a decrease in protein synthesis, as ribosomes are the primary machinery for this process.
