Answer:
The double membrane of the mitochondria is highly folded,and therefore wider when unfolded than that of the nucleus.This is an adaptive feature to increase the surface area for reactions (electrochemical gradient) by accommodating protons pumped into it by the proton motive force(PMF) from the matrix to set up the electrochemical gradients needed to generate the energy needed by ATPase synthase enzymes for ATPs synthesis.
Required number of protons needed to be accommodated by the double membrane to generate enough energy for ATPase synthesis,therefore larger surface area is needed.
Explanation:
Mitochondria is the powerhouse of the cell, which is a membrane-bound organelle found in the eukaryotic cell. The inner layer of the mitochondria has cristae, which is absent in the outer layer.
Mitochondria is a membrane-bound organelle, which is composed of outer and inner layers.
The inner layer has cristae or folds, which increases the surface area for an electrochemical gradient.
The cristae are separated by cristae junctions, which are juxtaposed to the outer layer of the mitochondria.
The inner layer helps in electron transport and ATP synthesis. The membrane is surrounded by the mitochondrial matrix, which helps in the transportation of protein complexes during the citric acid cycle.
Therefore, the inner membrane of mitochondria has cristae whereas, the outer layer lacks the folds.
