WebHere are some ways that mitochondrial and chloroplast DNA differ from the DNA found in the nucleus: High copy number. A mitochondrion or chloroplast has multiple copies of its DNA, and a typical cell has many mitochondria (and, in the case of a plant cell, chloroplasts). As a result, cells usually have many copies – often thousands – of ...
WebThe mechanism of ATP synthesis appears to be as follows. During the transfer of hydrogen atoms from FMNH 2 or FADH 2 to oxygen, protons (H + ions) are pumped across the crista from the inside of the mitochondrion to the outside. Thus, respiration generates an electrical potential (and in mitochondria a small pH gradient) across the membrane ... polyurethane snow plow cutting edgeWebJun 8, 2024 · Mitochondria have their own (usually) circular DNA chromosome that is stabilized by attachments to the inner membrane and carries genes similar to genes … shannon imgurWebMitochondria (singular = mitochondrion) are often called the “powerhouses” or “energy factories” of a cell because they are the primary site of metabolic respiration in eukaryotes.
