What does selectively permeable membrane mean in science terms?
A selectively permeable membrane is able to either let some materials pass through it or prevent the passage of others. This is a simple concept, but selectively permeable membranes have a lot of different applications that can impact people’s lives. An example of a membrane that is selectively permeable is the skin. We can control what goes in and out of our skin by applying topical creams and lotions. The skin acts as a barrier to infection, so it’s important that it is
What does selectively permeable membrane mean in chemistry?
A selectively permeable membrane is one that allows some types of particles to pass through it while others are blocked from passing through. The type of particles that can pass through the membrane are called “permeants”. A membrane can be permeable to one type of particle while being impermeable to other types of particles. For example, a membrane that allows water to pass through but keeps other particles (like oil or bacteria) from passing through is called a hydrophilic membrane.
What does selectively permeable membrane mean in biology?
A selectively permeable membrane is one that can allow some particles to pass through it while keeping others out. These membranes are often natural, such as those in human cells, but can also be made. A good example of a synthetic membrane is the one separating the water from fuel in a water-powered car.
What does selectively permeable membrane mean in a sentence?
A selectively permeable membrane is a biological membrane that allows for the transport of specific substances in one direction. This allows the cell to control what enters and exits the cell. There are three types of selectively permeable membranes: diffusion, active, and facilitated transport, which will be discussed in more detail in the next section.
What is selectively permeable membrane mean in science?
A selectively permeable membrane is a biological or chemical barrier that allows specific substances to pass through while rejecting others. Examples of selectively permeable membranes include the skin, the digestive system, and the blood-brain barrier (BBB). The BBB is formed by the brain’s supportive glial cells; it protects the brain from toxins circulating in the blood while allowing essential nutrients to enter.
