mitokondriates

Mitokondriates is a term that refers to organelles found in eukaryotic cells. These organelles are often called the "powerhouses" of the cell due to their primary function: cellular respiration. During cellular respiration, mitokondriates convert glucose and oxygen into adenosine triphosphate (ATP), which is the main energy currency of the cell. This process involves a series of complex biochemical reactions, including the Krebs cycle and oxidative phosphorylation.

Mitokondriates have a unique double-membrane structure. The outer membrane is smooth, while the inner membrane is highly folded into structures called cristae. These folds increase the surface area of the inner membrane, which is crucial for the efficient production of ATP. Within the inner membrane is the mitochondrial matrix, which contains enzymes, ribosomes, and its own circular DNA. This mitochondrial DNA is inherited maternally, meaning it comes solely from the egg cell during fertilization.

The presence of their own DNA and ribosomes has led to the endosymbiotic theory, which proposes that mitokondriates originated from free-living bacteria that were engulfed by an ancestral eukaryotic cell. Over time, these bacteria evolved into the organelles we know today. Mitokondriates play vital roles not only in energy production but also in other cellular processes such as programmed cell death (apoptosis), calcium homeostasis, and the synthesis of certain steroids and heme. Dysfunctions in mitochondrial activity are implicated in a variety of diseases, including neurodegenerative disorders and metabolic diseases.
