Question

Which of the following is called the cell respiratory organelle?
A) Ribosomes
B) Lysosomes
C) Golgi bodies
D) Mitochondria

Answer 1

Hint: It is an organelle that is scattered throughout the cells. It is a double membrane organelle. It helps in ATP production.

Complete answer:
The ribosomes are bound to rough ER and are free to float in the cytoplasm. Ribosomes are very small and do not consist of membranes. The ears, hair, skin, and eyes contain ribosomes. The role of ribosomes is to assist with the synthesis of proteins and to produce proteins. Therefore, ribosomes do not have a role in respiration. Thus, the option A is incorrect.
In the cytoplasm, lysosomes are present as well. They have sort of a structure-like sac that is surrounded by a single membrane containing very potent digestive enzymes. The role of Lysosome is to destroy dying cells, organelles, toxins, and particles of food. Lysosome is known as a suicidal bag. Therefore, lysosomes do not have a role in respiration. Thus, the option B is incorrect.
In the Cytoplasm, the Golgi apparatus is a flattened, coated sac-like organelle that takes and modifies carbohydrates and proteins and bundles them. The Golgi apparatus is a collection of membranes that modifies carbohydrates and proteins, operating closely with the endoplasmic reticulum. Therefore, Golgi apparatus do not have a role in respiration. Thus, the option C is incorrect.
The mitochondria contain cellular respiration enzymes. It is also known as the powerhouse of cell. It is an organelle that functions as a digestive mechanism that takes nutrients, breaks them down and provides the cell’s energy. The method of generating cell energy is defined as cellular respiration. Mitochondria are the sites of cellular aerobic respiration that generates energy in the form of ATP and helps to convert molecules.

Thus, the correct answer is option (D) Mitochondria.

Note:For the regular functioning of the cell, cell organelles organize and act effectively. Few of them operate by giving form and protection, while others are involved in a cell's locomotion and reproduction. Within the cell, there are multiple organelles and they are divided into three groups depending on the absence or presence of the membrane.
