Question

question 5
ribosomes are organelles responsible for:
a cell movement and cell shape
b protein synthesis
c manufacturing lipids
d packaging \cell products\ for export
e energy production

Explanation:

Ribosomes are molecular machines in cells. They read the genetic code (mRNA) and assemble amino acids into proteins. This is called protein synthesis.

• Option A: Cell movement and shape are related to structures like cytoskeleton, not ribosomes.
• Option C: Lipid manufacturing is mainly done by smooth endoplasmic reticulum.
• Option D: Packaging cell products for export is a function of Golgi apparatus.
• Option E: Energy production (ATP) is mainly by mitochondria (in eukaryotes) or cell membrane (in prokaryotes).

Answer:

B. protein synthesis
