Question

Identify three major organelles involved in protein production and specify their functions.

a) Endoplasmic reticulum - protein synthesis, Golgi apparatus - packaging, Lysosomes - waste disposal
b) Ribosomes - protein synthesis, Endoplasmic reticulum - packaging, Golgi apparatus - waste disposal
c) Ribosomes - protein synthesis, Endoplasmic reticulum - packaging, Golgi apparatus - transportation
d) Nucleus - protein synthesis, Mitochondria - packaging, Lysosomes - waste disposal

Answer 1

The correct answer is (c): Ribosomes are responsible for protein synthesis, the Endoplasmic reticulum for packaging, and the Golgi apparatus for transportation of proteins.

Step-by-step explanation:

The three major organelles involved in protein production are:

1. Ribosomes - these are non-membrane bound organelles that synthesize proteins, functioning as the 'machines' in the cell's factory.
2. Endoplasmic reticulum (ER) - particularly the rough ER, which is studded with ribosomes and involved in the modification and packaging of proteins synthesized by ribosomes.
3. Golgi apparatus - modifies, sorts, and packages proteins for secretion or use within the cell, completing the protein production process.

The correct choice as it pertains to these three organelles is option (c): Ribosomes - protein synthesis, Endoplasmic reticulum - packaging, Golgi apparatus - transportation. Mitochondria are known as the 'power plants' of the cell but are not involved in protein production phases like packaging or synthesis.
