Q. Do the mitochondria create energy where does the energy come from?
Mitochondria, using oxygen available within the cell convert chemical energy from food in the cell to energy in a form usable to the host cell. NADH is then used by enzymes embedded in the mitochondrial inner membrane to generate adenosine triphosphate (ATP). In ATP the energy is stored in the form of chemical bonds.
Q. Why does the mitochondria need energy?
They produce energy in the form of a molecule called ATP (adenosine triphosphate) which gets used throughout the cell to power the different jobs it has to do. How mitochondria make energy is very important to us as it allows our cells to function and for us to move and be alive.
Q. Do mitochondria produce energy during respiration?
Mitochondria have an important role in cellular respiration through the production of ATP, using chemical energy found in glucose and other nutrients. Mitochondria are also responsible for generating clusters of iron and sulfur, which are important cofactors of many enzymes.
Q. What type of bacteria are mitochondria?
The endosymbiotic hypothesis for the origin of mitochondria (and chloroplasts) suggests that mitochondria are descended from specialized bacteria (probably purple nonsulfur bacteria) that somehow survived endocytosis by another species of prokaryote or some other cell type, and became incorporated into the cytoplasm.
Q. Do proteobacteria have mitochondria?
Consistent evidence has indicated that proto-mitochondria emerged from the α lineage of proteobacteria (Andersson et al.
Q. What evidence is there that mitochondria are derived from Alphaproteobacteria?
The simplest explanation of these data is that mitochondria evolved from a planktonic marine alphaproteobacterial lineage that participated in multiple inter-specific cell colonization events, in some cases yielding parasitic relationships, but in at least one case producing a symbiosis that characterizes modern …
