How lumen occurs in mitochondria?
Answers
In this, the lumen is divided into two distinct aqueous compartments ; outer and inner compartments.
=>The outer membrane forms continuous limiting boundary of the organelle.
=>The inner membrane forms a number of folds called the cristae towards the matrix.
=>They have their own DNA and ribosomes.
=>It produces energy in the form of ATP in aerobic respiration
Answer:
Mitochondria (singular = mitochondrion) are often called the “powerhouses” or “energy factories” of a cell because they are responsible for making adenosine triphosphate (ATP), the cell’s main energy-carrying molecule. ATP represents the short-term stored energy of the cell. Cellular respiration is the process of making ATP using the chemical energy found in glucose and other nutrients. In mitochondria, this process uses oxygen and produces carbon dioxide as a waste product. In fact, the carbon dioxide that you exhale with every breath comes from the cellular reactions that produce carbon dioxide as a byproduct.
In keeping with our theme of form following function, it is important to point out that muscle cells have a very high concentration of mitochondria that produce ATP. Your muscle cells need a lot of energy to keep your body moving. When your cells don’t get enough oxygen, they do not make a lot of ATP. Instead, the small amount of ATP they make in the absence of oxygen is accompanied by the production of lactic acid.
