Organelles are specialized structures within a cell that perform specific functions. Let’s examine the functions listed for each organelle:<\/section>\n
Mitochondria are often called the “powerhouses” of the cell because they are the primary sites of cellular respiration, the process that generates ATP (energy) by breaking down glucose and other fuel molecules.
\nChloroplasts (found in plant cells and algae) are the sites of photosynthesis, where light energy is converted into chemical energy in the form of glucose.
\nRibosomes are responsible for protein synthesis, translating messenger RNA (mRNA) into polypeptide chains.
\nThe endoplasmic reticulum (ER) is a network of membranes involved in protein and lipid synthesis. The Rough ER is studded with ribosomes and is particularly involved in synthesizing proteins that are destined for secretion, insertion into membranes, or transport to other organelles. It also plays a role in folding and transporting these proteins.<\/section>\n
Based on these well-established functions, the combination in option A correctly matches each organelle with its primary role.<\/section>\n","protected":false},"excerpt":{"rendered":"
