The primary function of the mitochondria is to produce ATP, the molecule that the cell uses for energy when carrying out essential functions. The process by which glucose is converted to ATP in the mitochondria is known as cellular respiration and occurs in mitochondria of both plant and animal cells.Know More
Mitochondria are comprised of two major membranes. The outer membrane controls which molecules are allowed to enter and exit the mitochondrion. The inner membrane contains specialized enzymes that work together the convert glucose to ATP, and it is the primary site of cellular respiration.
Mitochondria are found within all plant and animal cells. Cells that use more energy tend to have more mitochondria. If the energy needs of a cell increase, the mitochondria replicate to increase in number. For example, as an athlete begins to work his or her muscles harder, these muscle cells develop more mitochondria to keep up with their growing energy needs.
Mitochondria replicate independently of the rest of the cell, and they have their own DNA. For this reason, many scientists believe that mitochondria evolved from early prokaryotic bacteria that lived symbiotically inside of the cells of more complex organisms. The majority of proteins which mitochondria need to carry out cellular respiration are coded for in the mitochondrial DNA.Learn more in Molecular Biology & DNA
Mitochondrial deoxyribonucleic acid (DNA) is found in the mitochondria of a eukaryotic cell; it is composed of 37 genes that are necessary for the mitochondria's function. Nuclear DNA, on the other hand, is found in the nucleus of a cell and is composed of 46 chromosomes that contain hereditary genetic information.Full Answer >
Mitochondrial DNA is DNA that is present inside the mitochondria of a cell. Mitochondrial DNA is not part of the DNA found in cellular chromosomes.Full Answer >
The primary function of DNA is to send the instructions needed for the development, survival and reproduction of living organisms. DNA contains information required to create proteins, and proteins are used to complete specific functions. Proteins are complex molecules that serve different functions and provide physical characteristics to organisms. To accomplish different functions, DNA sequences are transformed into messages that are used to produce proteins.Full Answer >
According to MedlinePlus, the primary function of fibrinogen is to help form blood clots. This protein, which is measurable with a blood test, is made in the liver.Full Answer >
