Why are folded membranes important?
A folded surface has more surface area than a flat surface. Inside the mitochondria, chemical reactions occur which produce energy for the cell. Since the reaction happens at the membrane surface, a folded membrane with increased surface area can produce more energy for the cell.
What is the purpose of the folded inner membrane 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 the advantage of an organelle having a folded membrane?
17. What is the advantage of having a folded inner membrane in the mitochondria? It increases the surface area.
What is a folded membrane?
One such organelle is the endoplasmic reticulum. This organelle is a highly folded membrane. The many folds result in more surface area for ribosomes to attach and thus allowing protein synthesis to occur at a more efficient rate. This organelle has two membranes one of which is folded inside the other.
What is the purpose of the folds of the inner mitochondrial membrane quizlet?
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.
Why are folds beneficial for the cell and organ?
The folding of the inner membrane increases the surface area inside the organelle. Since many of the chemical reactions happen on the inner membrane, the increased surface area creates more space for reactions to occur. If you have more space to work, you can get more work done.
What purpose do the folds in organelles serve for the cell?
The folded inner membrane create what is known as cristae and is the site for a portion of the cellular respiration process. The folds in this organelle also provide more surface area for this chemical process to occur.
Why is it important that the inner membrane of the mitochondria be folded in both plant and animal cells?
Why is it important that the inner membrane of the mitochondria be folded in both plant and animal cells? The folded membrane increases the structure strength of the mitochondria. The folded membrane increases the surface area for energy production.
What is the purpose of folding in organelles?
The fluid contained in the mitochondria is called the matrix. The folding of the inner membrane increases the surface area inside the organelle. Since many of the chemical reactions happen on the inner membrane, the increased surface area creates more space for reactions to occur.
Why does the folding of the inner mitochondrial membrane benefit aerobic respiration?
How does the arrangement of the cristae in the inner membrane of mitochondria affect the rate of aerobic respiration? Explain. The numerous folds of the inner mitochondrial membrane increase the surface area for additional electron transport chains. A high rate of aerobic respiration results.
How does the folding of the inner mitochondrial membrane benefits aerobic respiration?
Cristae are folds of the inner mitochondrial membrane. The cristae increase the surface area of the inner membrane, allowing for faster production of ATP because there are more places to perform the process.
What is the advantage of highly folded membranes in a cell?
An organelle with such highly folded membranes can be endoplasmic reticulum. The many folds result in more surface area for ribosomes to attach and thus allowing protein synthesis to occur at a more efficient rate.
What is the function of the folds within the mitochondria?
The function of the folds within the mitochondria is to increase the surface area of the mitochondrial membrane. Basically, the physical form of a structure can increase or decrease its surface area to volume ratio.
How does the plasma membrane in a cell work?
The plasma membrane controls the passage of organic molecules, ions, water, and oxygen into and out of the cell. Wastes (such as carbon dioxide and ammonia) also leave the cell by passing through the plasma membrane. We will cover the plasma membrane in more detail in a later unit but here is an overview of this cell surface structure.
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.
