Result

Your answer: — · Correct: A

Explanation

The correct combination of organelles and their functions is provided in Option 1. Mitochondria are the primary sites for cellular respiration, where glucose is broken down to release energy in the form of ATP [4]. Chloroplasts are specialized organelles in plants that contain chlorophyll and facilitate photosynthesis, converting sunlight, water, and carbon dioxide into glucose [3]. Ribosomes are the universal sites for protein synthesis (translation), where amino acids are linked together based on mRNA sequences. The Rough Endoplasmic Reticulum (RER) is studded with ribosomes and is primarily involved in the synthesis and transport of proteins, particularly those destined for secretion or membrane insertion [3]. While ribosomes synthesize the proteins, the RER provides the structural framework for their initial modification and transport within the cell's endomembrane system.
