Question

Which among the following statements is incorrect about mitochondria?

(a) Mitochondria is a rod-shaped organelle bounded by two membranes and is also called as the power house of the cell

(b) Mitochondria has an outer membrane, an inner membrane, cristae and matrix

(c) The inner membrane of the mitochondria is highly folded and these folds provide greater surface area for the generation of ATP molecules

(d) Mitochondria can’t synthesize their own proteins and depend on rough endoplasmic reticulum

I have been asked this question in an international level competition.

My question comes from Organelles in Eukaryotic and Prokaryotic Cells in portion Cell : The Unit of Life of Biology – Class 11

Answer 1

Right answer is (d) Mitochondria can’t synthesize their own proteins and depend on rough endoplasmic reticulum

Explanation: Mitochondrion is a rod-shaped organelle bounded by two membranes and is also called as the power house of the cell. Mitochondrion has an outer membrane, an inner membrane, cristae and matrix. The inner membrane of the mitochondria is highly folded and these folds provide greater surface area for the generation of ATP molecules. Mitochondria can synthesize their own proteins since they have ribosomes and genetic material in them.
