To increase the surface area.
I think you are referring to the cristae. These are the folded parts of the inner membrane. The purpose is to increase surface area of the inner membrane against the matrix. The membrane is the site of the energy transfer in the mitochondria, so having more surface area is a plus.
Cristae (singular; crista)
The inner mitochondrial membrane is highly folded
Cristae (singular; crista)
This description matches the structure of mitochondria. The outer membrane of mitochondria surrounds the organelle, while the inner membrane is folded into numerous layers called cristae, which help increase the surface area for energy production through oxidative phosphorylation.
Folded rock layers create monoclines, synclines and anticlines.
Yes, both the nucleus and mitochondria are surrounded by two layers of unit membrane. The nucleus is surrounded by the nuclear envelope, made up of two lipid bilayers, while the mitochondria have an outer and inner mitochondrial membrane.
Mitochondria
Yes, the nuclear membrane consists of two layers, just like the plasma membrane.
The organelle that contains a smooth outer membrane and a folded inner membrane in a cell is the mitochondrion. Mitochondria are responsible for producing energy in the form of ATP through a process called cellular respiration.
Folded mountains are large mountain ranges that form through the folding of rock layers due to tectonic plate movements. These mountains typically have long ridges and valleys, with the rock layers appearing bent and folded. Examples include the Himalayas and the Appalachians.
Folded mountains are formed when rock layers are bend under stress.
