Which property of a cell allows it to maintain homeostasis?
The structure and properties of the cell wall allow it to be selective and maintain homeostasis. The plasma membrane is a bilayer of lipid molecules with protein molecules embedded in it. You just studied 7 terms!
Which process removes materials from a cell?
Exocytosis occurs when a vesicle fuses with the plasma membrane, allowing its contents to be released outside the cell. Exocytosis serves the following purposes: Removing toxins or waste products from the cell’s interior: Cells create waste or toxins that must be removed from the cell to maintain homeostasis.
How is the cell membrane regulate the movement of materials into or out of the cell?
The cell membrane is selectively permeable, allowing only a limited number of materials to diffuse through its lipid bilayer. During passive transport, materials move by simple diffusion or by facilitated diffusion through the membrane, down their concentration gradient.
What does the cell membrane do?
Cell membranes protect and organize cells. All cells have an outer plasma membrane that regulates not only what enters the cell, but also how much of any given substance comes in.
What four conditions in the body are related to maintaining homeostasis?
The body maintains homeostasis for many factors. Some of these include body temperature, blood glucose, and various pH levels. Homeostasis is maintained at many levels, not just the level of the whole body as it is for temperature.
How is the plasma membrane selective and maintain homeostasis?
The structure and properties of the cell wall allow it to be selective and maintain homeostasis T or F? The plasma membrane is a bilayer of lipid molecules with protein molecules embedded in it T or F? A phospholipid molecule has a nonpolar, water-insoluble head attached to a long polar, soluble tail
How does the cell take up liquid from the environment?
(Taking up liquids) cells take up liquid from the surrounding environment. Tiny pockets form along the cell membrane, fill with liquid, and pinch off to form vacuoles (vesicles) within the cell Exocytosis The membrane of the vacuole surrounding the material fuses with the cell membrane, forcing the contents out of the cell.
How are T or F proteins used in the plasma membrane?
T or F? transport proteins span the cell membrane, creating the selectively permeable membrane that regulates which molecules enter and leave a cell T or F? Proteins at the inner surface of the plasma membrane attach the membrane to the cell’s support structure, making the cell rigid
What makes the eukaryotic plasma membrane more stable?
T or F? Eukaryotic plasma membranes can contain cholesterol, which tends to make the membrane more stable T or F? transport proteins span the cell membrane, creating the selectively permeable membrane that regulates which molecules enter and leave a cell T or F?
