What are the folded membranes inside the cell?
Endoplasmic reticulum (ER): a series of folded membranes enclosing cisternae. important for internal transport within the cell; may be rough (with ribosomes on surface) or smooth (no ribosomes)
What is the purpose of having highly folded membranes in organelles?
The folding increases the surface area where chemical reactions occur.
What is the advantage of having folded membrane within the cytoplasm?
Mitochondrion) has outer membrane and inner membrane. The inner membrane known as the Cristae is folded. The folds of the inner membrane or the Cristae provide an increase in the Surface Area which gives the Mitochondrion more locations for ATP( the energy currency) production to occur.
What is the purpose of the folded inner membrane inside of the mitochondria?
To increase the capacity of the mitochondrion to synthesize ATP, the inner membrane is folded to form cristae. These folds allow a much greater amount of electron transport chain enzymes and ATP synthase to be packed into the mitochondrion.
What is a folded membrane?
A protein called TMCO1 is part of a larger protein machine that transports transmembrane proteins into the endoplasmic reticulum and helps fold them within the membrane. As the new protein is made by the ribosome, it enters the endoplasmic reticulum membrane where it folds into the correct shape. …
What is the purpose of stacking and folding of membranes in the organelles of eukaryotes?
A mitochondrion has an outer membrane and a highly folded inner membrane. These folds of the inner membrane provide a greater surface area for the various chemical reactions to take place.
What is the purpose of the folds of the inner mitochondrial membrane quizlet?
Explain. The numerous folds of the inner mitochondrial membrane increase the surface area for additional electron transport chains. Increased surface area also allows more area for protons to accumulate outside the membrane to increase the concentration gradient necessary for chemiosmosis.
What is the importance of the inner membrane?
The inner or cytoplasmic membrane, impermeable to polar molecules, regulates the passage of nutrients, metabolites, macromolecules, and information in and out of the cytoplasm and maintains the proton motive force required for energy storage.

What does the folding of the mitochondrial inner membrane?
Why does the folding of the inner mitochondrial membrane benefit aerobic respiration?
Part of cell respiration happens by transferring molecules across the inner membrane, so by adding folds, a longer piece of membrane can be stuffed inside the mitochondria. This increases the amount of molecules that can be transferred across it. Increasing surface area can be seen in many other parts of the body too.
What is the purpose of the inner mitochondrial membrane?
Consequently, the inner mitochondrial membrane is the functional barrier to the passage of small molecules between the cytosol and the matrix and maintains the proton gradient that drives oxidative phosphorylation.
How do folded membranes increase the surface area of a cell?
Since the reaction happens at the membrane surface, a folded membrane with increased surface area can produce more energy for the cell. Answer 2: They increase the surface area of the inner membrane, allowing there to be more proteins and more exchange of ions across the membrane, allowing the mitochondrion to do its job more quickly. Answer 3:
What is the function of folds in the mitochondria?
Answer 2: They increase the surface area of the inner membrane, allowing there to be more proteins and more exchange of ions across the membrane, allowing the mitochondrion to do its job more quickly. The function of the folds within the mitochondria is to increase the surface area of the mitochondrial membrane.
What is the function of the inner membrane of the mitochondria?
This inner folded part of the mitochondria (the inner membrane) is responsible for cell respiration (the process of breaking down carbohydrates (sugars) to make energy). Part of cell respiration happens by transferring molecules across the inner membrane, so by adding folds, a longer piece of membrane can be stuffed inside the mitochondria.
Why does the mitochondrial membrane have a high surface area?
The reason mitochondrial membranes need a high surface area is because the process of using oxygen to make energy is carried out on this membrane. The larger the surface area of this membrane, the more room for the membrane-bound cellular machinery that uses oxygen to make energy.
