The structure of the cell membrane allows it to be selectively permeable. What is the name for the larger, brown structure in th
Anika [276]

Explanation:

B) protein channel

Lipids are composed of fatty acids which form the hydrobic tail and glycerol which forms the hydrophilic head; glycerol is a 3-Carbon alcohol which is water soluble, while the fatty acid tail is a long chain hydrocarbon (hydrogens attached to a carbon backone) with up to 36 carbons.

Their polarity or arrangement can give these non-polar macromolecules hydrophilic and hydrophobic properties. Via <em>diffusion,</em> 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. The hydrophilic heads of the bilayer are attracted to water while their water-repellent hydrophobic tails face towards each other- allowing molecules of water to diffuse across the membrane along the concentration gradient.

Transmembrane proteins are embedded within the membrane from the extracellular fluid to the cytoplasm, and are sometimes attached to glycoproteins (proteins attached to carbohydrates) which function as cell surface markers. Carrier proteins and channel proteins are the two major classes of membrane transport proteins.

  • Carrier proteins (also called carriers, permeases, or transporters) bind the specific solute to be transported and undergo a series of conformational changes to transfer the bound solute across the membrane. Transport proteins spanning the plasma membrane facilitate the movement of ions and other complex, polar molecules  which are typically prevented from moving across 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

Drag each tile to the correct box. Explain the process in which hormones secreted by the pancreas function with respect to incre
ValentinkaMS [17]

Answer:

1) intake of glucose molecules from the blood by specific transporters

2) high amount of glucose in the blood, sending signals toward the pancreas

3) binding of hormones with receptors on the liver

4) release of hormones from the receptors

5) synthesis of hormones by beta cells

Explanation:

During ingestion of the meal, insulin is produced in response to high blood glucose levels (concentration of glucose increases after digestion of food). Like other hormones, insulin performed its action through binding specific signals to specific receptors e.g, liver, muscle cells.  The high glucose level in the blood send signals through hormones to liver, fat, and muscle cell receptors. These receptors release specific hormones to beta cells of the pancreas. In response to the signals from receptors, beta cells synthesize insulin to minimize glucose levels in the bloodstream.
