Mitochondria are tiny organelles found in nearly all eukaryotic cells. They are rather large organelles ranging from 0.5µm to 10µm in length and 1µm in diameter. The mitochondria are the energy factories of the cell and are located in the cytoplasm. They are the sites of cellular respiration. The mitochondria are responsible for generating ATP from such organic fuels as simple sugars and fats in the process of cellular respiration. This doubled-membrane organelle has its own DNA and can reproduce by splitting itself.
The mitochondria are sausage-shaped structures that move, change their shape and divide. They are distinct organelles with two membranes, the inner membrane and the outer membrane. The outer membrane is smooth …show more content…
The mitochondrial matrix contains enzymes that catalyse many metabolic steps of cellular respiration. Some enzymes are actually embedded in the inner membrane.
The purpose of the mitochondria is to power the cell. These organelles take in glucose and oxygen and break them down to provide ATP (a substance that is an important store of chemical energy for cells). This process is called cellular respiration.
They perform almost the exact opposite function of the chloroplasts, which provide all the materials necessary for cellular respiration through the process of photosynthesis. The chloroplasts develop the materials necessary for providing the cell with energy, and the mitochondria use the materials to manufacture it.
Cellular respiration takes place in three main stages. Each of these three stages is a complex biochemical pathway.
The first stage of cellular respiration is glycolysis, which take place outside of the mitochondrion. Glycolysis is the pathway by which a molecule of glucose is broken down into two molecules of pyruvate. During Glycolysis, the six-carbon glucose molecule is split into 2 three-carbon molecules. During this process energy is also given off. Some of this energy is lost as heat,
