How does simple diffusion differ from facilitated diffusion?

Facilitated diffusion crosses a membrane with the aid of passive transport proteins in the membrane.

Artyom0805 [142]3 years ago
5 0

Both simple and facilitated diffusion are spontaneous, meaning they require no energy for it to occur. Simple diffusion is for nonpolar molecules because they are able to pass through the nonpolar/hydrophobic membrane easily, whereas polar (hydrophilic) molecules have a hard time. Facilitated diffusion makes it easier for polar molecules to go through the membrane WITH the help of protein channels.

So the difference is that facilitated uses protein channels whereas simple does not.

What are the the functions of a cytoplasm? Help make proteins, help a cell keep it shape, surrounds the cell, contains DNA
Andrei [34K]
The cytoplasm provides a medium for the organelles to remain suspended. The cytoplasm acts as a buffer and protects the genetic material of the cell and also the cellular organelles from damage caused due to movement and collision with other cells. Cellular respiration begins in the cytoplasm with glycolysis.

In general, how does biodiversity vary across the biosphere?
Tamiku [17]
Life needs energy, water, heat and nutrients. Reduce the availability of one or more of those things and biodiversity generally decreases.

Tropical forests tend to be more diverse than polar ice caps. However, arctic seas tend to be more biologically interesting than the middle of the Sahara. I bet this is what your homework is looking for but it's important to remember there are counterexamples.

Mammals do not produce digestive enzyme B. However, sheep and cattle are two types of mammals that contain microorganisms in the
Lady bird [3.3K]

Answer:

The correct option is this: A specific enzyme removes the hydrogen from the monosaccharide and the hydroxide from the polysaccharide, creating a bond between the two and creating a water molecule.

Explanation:

The process by which a monosaccharide molecule is added to an existing polysaccharide in biological systems is called CONDENSATION POLYMERIZATION.

During the process of condensation, an hydrogen atom and an hydroxide molecule from the reactants come together to form a water molecule; this leads to the formation of covalent bond between the reactants.

Condensation reaction is used in living organisms to produce complex macro molecules such as carbohydrates, proteins and lipids, which are needed by the body for health growth.

Remember, condensation reaction always results in loss of water molecules and formation of more complex molecule. One example of monosaccharide is glucose while cellulose (found in plants) and starch (found in animals) are examples of polysaccharides.
