The concept that explains the presence of mitochondria in cells is the endosymbiotic theory. Mitochondria in cells derived from the extra embryonic membranes.
OK so first all the concept that's explains the presents of the mitochondria in the cell is because it helps the cell wall in a plant cell so that inside of the cell doesn't get damaged so mostly its another cell wall but its called mitochondria i know this because I'm in 6th grade and i am doing a project right now on oct,10,2012 cause its due oct,11,2012 so if u don't believe me u can even ask you teachers
Presence of extra-chromosomal DNA: Mitochondria and chloroplasts
mitochondria
The mitochondria is the site of most of cellular respiration, same glycolysis. Through the Kreb's cycle and oxidative phosphorilation the mitochondria produce the energy currency of the cell; ATP. The endosymbiotic theory explains the presence of the mitochondria as a fusing or ingesting of a type of aerobic bacteria many eons ago.
Cellular aerobic respiration occurs within the mitochondria.Cellular respiration occurs in the mitochondria of a cell. Mitochondria are the "cellular power houses" that conduct oxygen and glucose through the cell to the other mitochondria, which use the oxygen and glucose to power the cell. After being used, the oxgen and glucose is transformed into carbon dioxide and water.
The mitochondria is responsible for providing a cell with its energy by oxidizing food molecules through a process called cellular respiration. This organelle generates ATP, the energy currency of the cell, through the breakdown of glucose and other nutrients in the presence of oxygen.
Mitochondria likely originated from a symbiotic relationship between a primitive eukaryotic cell and an aerobic prokaryotic cell, possibly an ancestor of modern-day alphaproteobacteria. This symbiosis likely occurred through endosymbiosis, where the prokaryotic cell was engulfed by the eukaryotic cell but not digested, leading to a mutually beneficial relationship where the host cell provided a protected environment and the prokaryotic cell provided ATP through aerobic respiration.
The majority of a cell's ATP is produced through the process of cellular respiration, where glucose is broken down in the presence of oxygen to generate ATP in the form of chemical energy. This process mainly occurs in the mitochondria of eukaryotic cells.
ATP is produced in the mitochondria by the process of cellular respiration.
This cell could be from a plant, animal, or any other eukaryotic organism. The presence of enzymes, DNA, ribosomes, plasma membrane, and mitochondria suggests it is a eukaryotic cell.
