Compare and contrast the extracellular matrix of animals and the cell wall of plants. Consider their functions and the types of
mario62 [17]

Answer:

The plant cell wall is strengthened by the molecular structure of cellulose. Cellulose is made up of ß-glucose arranged upside down, this arrangement aided hydrogen bonds between the hydrogen ions of the  hydroxyl group and oxygen of the of the ring   of same  betta -glucose.

The aggregation of the hydrogen  bonds give bundles of  strong tensile  strength of cellulose called the  microfibrils (of 60-70 celluose molecules).They are  held together in bundled called fibers.T<u>hese is the source of  plant cell walls  strength. </u>

<u />

Collagen is the main extracellur matrix (EM) in animal cells.It is a glycoprotein made up of 25%of body protein of animals.Each collagen molecule is made of helix shaped ,three polypeptide chains, wound around each other to form<u> triple helix.</u>The bonds  holding helix together are hydrogen and covalent bonds.

Each triple helix is attached to adjacent collagen molecule, parallel  to it. The covalent bonds formed a cross link which held  the collagen molecules together forming FIBRILS.  This gives flexibility to collagen, while maitaing strong tensile strength. This is what is responsible for the structural strength of cell membrane .

.The  EM,is  futher reinforced with  carbohydrate molecules(proteoglycans) which<u> aided in water movements by  osmosis following  sodium movements into the matrix.</u>

ction potentials typically move in one direction along the neuron away from the cell body. This is due to which of the following
aleksklad [387]

Answer:

The correct answer is option A. "the temporary hyperpolarization of the axon membrane following the action potential spike".

Explanation:

Action potentials, also known as "spikes" or "impulses", are electric impulses that neurons use to send information from the cell's body down to the axon. The impulses are created when ions travel across the neuron's membrane creating a depolarization current. This depolarization current is responsible for an temporary hyperpolarization of the axon membrane following the action potential spike. When neurons are hyperpolarized they are not able to produce another action potential. In consequence, actions potentials move in one direction along the neuron away from the cell body, as well as, adjacent locations go trough similar depolarization processes.
