Question

3. Mitochondria a) are the sites of protein synthesis in the cell
b) are mainly found in vacuoles c) are smaller than chloroplasts
d) are a part of Golgi bodies e) have no internal structure

Answer 1

Mitochondria are the sites of protein synthesis in the cell apart from the ribosomes.

Hence the correct answer is a. Inner membrane of mitochondria is loaded with proteins which are involved in the ATP synthesis and electron transport.

The membrane surrounds mitochondrial matrix, where citric acid cycle forms the electrons which travel from a protein complex to next in inner membrane.
