Question

essay and Short note on mitochondria ​

Answer 1

Answer:

Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. The biochemical processes of the cell are known as cellular respiration.

Answer 2

Answer:

Mitochondria:-

Mitochondria are membrane-bound organelles present in the cytoplasm of all eukaryotic cells, that produces adinosine triphosphate (ATP), the main energy molecule used by the cell.”

They play a major role in breaking down nutrients and generating energy-rich molecules for the cell. Many of the biochemical reactions involved in cellular respiration take place within the mitochondria. The term ‘mitochondrion’ is derived from the Greek words “mitos” and “chondrion” which means “thread” and “granules-like” respectively. It was first described by a German pathologist named Richard Altmann in the year 1890.

❥The mitochondrion is a double-membraned, rod-shaped structure found in both plant and animal cell.

❥Its size ranges from 0.5 to 1.0 micrometre in diameter.

❥The structure comprises an outer membrane, an inner membrane, and a gel-like material called the matrix.

❥The outer membrane and the inner membrane are made of proteins and phospholipid layers separated by the intermembrane space.

❥The outer membrane covers the surface of the mitochondrion and has a large number of special proteins known as porins.

❥It is freely permeable to ions, nutrient molecules, energy molecules like the ADP and ATP molecules.
