does it have any co-relation with calcium?
The concentrations of free calcium in the cell can regulate an array of reactions and is important for signal transduction in the cell. Mitochondria can transiently store calcium, a contributing process for the cell's homeostasis of calcium.

where is the mitochondria located in an animal cell UNANSWERABLE what is the main topic in discussion? Mitochondrion. what is it's structural composition? They contains outer and inner membranes composed of phospholipid bilayers and proteins, that have different properties. Because of this double-membraned organization, there are five distinct parts to a mitochondrion. what does the first membrane mentioned consist of? It contains large numbers of integral membrane proteins called porins. and what does the other membrane consist? It contains more than 151 different polypeptides, and has a very high protein-to-phospholipid ratio. what is the functionality of the main topic in discussion? The most prominent roles of mitochondria are to produce the energy currency of the cell, through respiration, and to regulate cellular metabolism.

Mitochondrion [SEP] Storage of calcium ions
The concentrations of free calcium in the cell can regulate an array of reactions and is important for signal transduction in the cell. Mitochondria can transiently store calcium, a contributing process for the cell's homeostasis of calcium. Ca influx to the mitochondrial matrix has recently been implicated as a mechanism to regulate respiratory bioenergetics by allowing the electrochemical potential across the membrane to transiently "pulse" from ΔΨ-dominated to pH-dominated, facilitating a reduction of oxidative stress. In neurons, concomitant increases in cytosolic and mitochondrial calcium act to synchronize neuronal activity with mitochondrial energy metabolism. Mitochondrial matrix calcium levels can reach the tens of micromolar levels, which is necessary for the activation of isocitrate dehydrogenase, one of the key regulatory enzymes of the Krebs cycle.
