What is the advantage of having a folded membrane within the cytoplasm?
The plasma membranes of cells that specialize in absorption are folded into fingerlike projections called microvilli (singular = microvillus). This folding increases the surface area of the plasma membrane. Such cells are typically found lining the small intestine, the organ that absorbs nutrients from digested food.
What are the advantages of membrane bound organelles?
Membrane-bound organelles offer several advantages to eukaryotic cells. First, cells can concentrate and isolate enzymes and reactants in a smaller volume, thereby increasing the rate and efficiency of chemical reactions.
What is the advantage of having a folded inner membrane in 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.
Why are there so many cells that have folded membranes?
We’re reducing MSN tuition by 14% and offering scholarships so more caring nurses can become FNP leaders. It is meant to maximize surface size. Cells that need a lot of activity on the surface therefor have a folded membrane. What are the stages of protein synthesis?
How are plasma membranes folded in eukaryotic cells?
The plasma membranes of cells that specialize in absorption are folded into fingerlike projections called microvilli (singular = microvillus). This folding increases the surface area of the plasma membrane.
How does a folded surface relate to the mitochondria?
A folded surface has more surface area than a flat surface. Imagine an accordion, which looks small when it’s bunched up, but actually can be stretched out due to its folds. So, how does this relate to the mitochondria? Inside the mitochondria, chemical reactions occur which produce energy for the cell.
Is the plasma membrane part of the endomembrane system?
Although not technically within the cell, the plasma membrane is included in the endomembrane system because, as you will see, it interacts with the other endomembranous organelles. Typically, the nucleus is the most prominent organelle in a cell (Figure 4).
