Verified step by step guidance

Understand the role of ribosomes in protein synthesis: Ribosomes are the cellular structures responsible for protein synthesis. They can be found either free in the cytosol or bound to the endoplasmic reticulum (ER).

Differentiate between free and bound ribosomes: Free ribosomes synthesize proteins that function within the cytosol, while bound ribosomes, attached to the ER, synthesize proteins destined for secretion, incorporation into the cell membrane, or for use in lysosomes.

Identify the types of proteins synthesized by bound ribosomes: Bound ribosomes are primarily involved in the synthesis of secretory proteins, membrane proteins, and lysosomal proteins.

Analyze the options given: Mitochondrial proteins, cytosolic enzymes, and nuclear proteins are typically synthesized by free ribosomes, as they function within the cell and are not secreted.

Conclude that secretory proteins are synthesized by bound ribosomes: Based on the understanding of ribosome function and protein targeting, secretory proteins are the correct answer as they are synthesized by ribosomes bound to the ER.
