Facilitated diffusion and active transport

<span>Facilitated diffusion is the movement of large particles (that cannot otherwise move across the cell membrane) from an area of higher concentration to an area of lower concentration with the help of trans-membrane proteins.</span>

<span>Active transport is the movement of molecules across a cell membrane from a region of lower concentration to a region of higher concentration using ATP energy. this may occur with large particles that cannot move across the cell membrane or small ones that can but don't due to the concentration gradient.</span>

<u>Answer</u>: Sustainable development

<u>Explanation</u> :

The concept of sustainable development is based on the ideas of sustainable forest management and is derived from the Brundtland Report (1987).

It is basically an organizing principle which states that the human developmental goals should be met by maintaining the stability of the natural systems so that the natural sources can be sustained for future use as well.

So,<em> sustainable development basically means that the present needs should be met without comprising the needs of future generations.</em>

Answer and Explanation:

Protein is one of the most important molecules in our organism, being present in the composition of all elements, in addition to participating in several metabolic processes. This importance creates the need to study this molecule, however, to study it it is necessary to know the composition chemistry and the levels of structure it presents.

The chemical composition of proteins is related to amino acids, since protein is formed by them. In this case, we can say that the proteins have the same composition as the amino acids containing carboxylic acid and different amino groups, which is what determines the name and function of the amino acid.

In addition to chemical composition, the structure levels of proteins are extremely important, as they only function at a specific structural level. As for these levels, proteins can have a primary structure (there are more than two amino acids organized in a linear row), a secondary structure (when the primary structure turns into a helix species), a tertiary structure (formed by a more intense folding of the secondary structure providing the appearance of helices and leaves) and quarternary structure (when several tertiary structures are joined, allowing folding at the three-dimensional level. This is the functional structure of the protein).
