What do cells want to being in and what do cells want to keep out

PilotLPTM [1.2K]

Answer:

Cell membranes serve as barriers and gatekeepers. ... Small polar molecules, such as water and ethanol, can also pass through membranes, but they do so more slowly. On the other hand, cell membranes restrict diffusion of highly charged molecules, such as ions, and large molecules, such as sugars and amino acids.

Hope it helps :)

Natalka [10]

Explanation:

From the diagram with corresponding labels:

Exocytosis
Facilitated diffusion
Endocytosis
Diffusion
Active transport

Further explanation:

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

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

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.

Structure is the result of two or more protein subunits assembling to form a larger, biologically active protein complex.

cluponka [151]

A larger, biologically active protein complex is created when two or more protein subunits come together to form a quaternary structure.

A protein's quaternary structure is formed when several protein chains or subunits come together in a compact configuration. There are separate primary, secondary, and tertiary structures for each of the subunits. Hydrogen bonds and van der Waals forces between nonpolar side chains hold the subunits together.

For a quaternary structure to function as a whole, the subunits must be arranged in a particular way. Any change to the subunits' structure or how they are linked results in noticeable adjustments in biological activity.

Sedaia [141]

Endospore is a protective structure that can able to survive for long periods of time in soil and water in which they commonly found. They are tough, dormant and non-reproductive structure which can withstand heat, dryness, and toxic chemicals that would kill most other bacteria produced by a small number of bacteria like the bacterium Bacillus thuringiensis from the Firmicute family. To ensure the survival of a bacterium through periods of environmental stress is the primary function of most endospores. They are also resilient to gamma and ultraviolet radiation, chemical disinfectants, desiccation, starvation, lysozyme and temperature and can survive any environmental assaults.
