Explanation:

<u></u>

<u>From the diagram with corresponding labels:</u>

  1. Exocytosis
  2. Facilitated diffusion
  3. Endocytosis
  4. Diffusion
  5. Active transport

<u>Further explanation:</u>

Via diffusion, small water molecules can move across the phospholipid bilayer acts as a semi-permeable membrane into the extracellular fluid or the cytoplasm which are both hydrophilic and contain large concentrations of polar water molecules or other water-soluble compounds.

Via osmosis, the water passes through the membrane due to the difference in osmotic pressure on either side of the phospholipid by layer this means that the water moves from regions of high osmotic pressure/concentration to regions of low pressure/ concentration to a steady state.

Active transport is a mediated process that requires the use of specialized membrane proteins these proteins require energy in the form of avenues and triphosphate or ATP in order to facilitate necessary conformational changes to the large protein molecules.

Carrier proteins and channel proteins are the two major classes of membrane transport proteins; these allow large molecules called solutes (including essential biomolecules) to cross the membrane. Channel proteins which are pores filled with water versus enabling charged molecules to diffuse across the membrane,  from regions of high concentration to regions of lower concentration. This is a passive part of facilitated diffusion

<em>...some very large molecules require specialized type of active transport in order to move across the membrane this includes endocytosis and exocytosis</em>

<em> </em>

During endocytosis large molecules cells and cell fragments moved across the plasma membrane through a process of invagination; piece of the external cell membrane falls into itself and forms a small pocket that surrounds the target molecule this breaks off from the membrane to form an intracellular vesicle; different methods of endocytosis such as Phagocytosis, Pinocytosis and receptor-mediated endocytosis, take in cells,  water and targeted substances respectively.

Similarly, in exocytosis, the particles (Protein, Waste material etc.) surrounded by a phospholipid membrane. However, this membrane is formed in the cytoplasm, and attaches to the plasma membrane’s interior in a process opposite to endocytosis;  material is removed from the cell and exported into the cell’s exterior called the extracellular space.

Answer:

Considering the organization of the body the level of organization in which proteins like collagen are found is the molecular level, and this level of organization allows the construction of the structure and functions of the whole body.

Explanation:

Collagen is a protein molecule that belongs to the molecular organization level, like all biomolecules.

Proteins have multiple functions in the body:

  • <em>They participate in the construction or structure of the body. </em>
  • <em>They form specialized proteins, the enzymes, to facilitate organic chemical reactions. </em>
  • <em>They are part of the structure of cell membranes, allowing cellular recognition and transmembrane transport. </em>

In this way <u>the protein molecules, belonging to the molecular level, contribute to the organization of the whole body</u>.
