What is the difference between plasma membrane and cell membrane?

Biology

The plasma membrane is the boundary between the cell and its environment. It regulates what enters and exits the cell. Cells must maintain an appropriate amount of molecules to function inside them. They must also have a way to keep things out or to allow things to enter. This is the job of the plasma membrane. The plasma membrane is like the guard at a gated community. The guard must inspect those who enter and those who leave to make sure that only the people and things needed in the community are there.

The cell membrane is a thin semi-permeable membrane that surrounds the cytoplasm of a cell. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell, while keeping other substances out. It also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. Thus the cell membrane also serves to help support the cell and help maintain its shape.

laila [671]

<u>Answer:</u>

Effects Include:

Activates secondary messengers such as cAMP which further activates number of hormones like

  • ADH: production of this hormone causes kidneys to retain more water inside body.
  • GHRH: release growth factors and stimulates growth of organism.
  • ACTH: produces fight or flight responses i.e rise in heart beat, rise in Blood pressure etc
  • TSH: Stimulate the synthesis of Thyroid hormone and enhances the metabolism of body. In rare cases causes Goiter without the deficiency of Iodine.
  • LH: Stimulate follicle maturation and formation of ovules in women.
  • Calcitonin: Decreases blood calcium level by deposition calcium in bones. This effect weakens the muscles.
  • Glucagon: Stimulates glycogen breakdown from liver and muscles and many more effects.

<u>Explanation:</u>

Background Knowledge:

GPCR (G Protien coupled receptors) are present inside plasma membrane in huge amount. As name suggest that these receptors are coupled with G proteins during their inactive state present inside of the cell. During their Inactive state these G proteins are bounded with GDP molecule.

Upon receiving signal molecules from outside of cell alters the shape of GPCR. These receptors also triggers change in G Protein, as a result of this GTP get attached with them. This protein further activates reaction cascades inside of the cell.

What happen if GTP cannot be hydrolyzed to GDP + Pi?

If GTP cannot hydrolyzed in to GDP + Pi than, it cannot be able to dissociate from G proteins. Cascade system doesn't stop and produces many effects on body.

Effects Include:

Activates secondary messengers such as cAMP which further activates number of hormones like

  • ADH: production of this hormone causes kidneys to retain more water inside body.
  • GHRH: release growth factors and stimulates growth of organism.
  • ACTH: produces fight or flight responses i.e rise in heart beat, rise in Blood pressure etc
  • TSH: Stimulate the synthesis of Thyroid hormone and enhances the metabolism of body. In rare cases causes Goiter without the deficiency of Iodine.

What is a description of binary fission?
sergey [27]

Binary fission, is an asexual reproduction by, and it is when the body splits into two new bodies. In the process of binary fission, an organism duplicates its genetic material, (DNA), and then divides into two parts (cytokinesis), with each new organism receiving one copy of DNA. Hope this helps. c;
