What happens to proteins within the endoplasmic reticulum

Biology

The correct answer is A. They are synthesized. 

In the endoplasmic reticulum, proteins are synthesized on to the surface of a rough endoplasmic reticulum. With the help of ribosomes which contains mRNA, the small bounded organelles enter the chamber where mRNA which contains proteins is being released.
Endoplasmic reticulum also regulates the quality of the proteins.

A protein within the endoplasmic reticulum is synthesized.

Further Explanation:

In biology, Endoplasmic Reticulum (ER) is a continuous membrane system that makes a series of flattened sacs inside cytoplasm of the eukaryotic cells and provides multiple functions. All the eukaryotic cells consist endoplasmic reticulum. On the basis of their functional and physical characteristics they are divides into two types:

  • Smooth endoplasmic reticulum: They do not consist of any ribosome and synthesize lipids.
  • Rough endoplasmic reticulum: they consist of the ribosome on their outer surface because of this their surface is rough. They help in synthesizing protein.

Important functions of the ER are:

  • Synthesis protein
  • Protein folding
  • Protein modification
  • Transport of protein

Golgi apparatus is a folded membranous structure present in eukaryotic cells and has vital intracellular functions. It has flattened sacs in the membrane which are referred to as cisternae. ER synthesizes protein and transfers it to the Golgi apparatus.

Number 1: The Circulatory System is a vast network that contains organs and vessels.

number 2: Arteries have a thick wall which helps a powerful pressure from the heart.

number 3: Without the Circulatory System the body wouldn't be unable to maintain a internal environment.

number 4: The Circulatory and Respiratory system both have gas to help a or animal live in there internal environment.

number 5: Blood vessels brings oxygen to the tissues and absorbs carbon dioxide and other waste products to clear the lungs. And with out oxygen the tissues won't absorb carbon dioxide to clear out the lungs.

Which have scientists learned from studying seismic waves that travel through earth’s interior?
DENIUS [597]
<span><span>D. They have learned the precise depths where the boundaries between the earth's layers are located.</span>

The overwhelming amount of seismic activity particularly happens along convergent plate boundaries. In particular, reverse or thrust faults occurs on convergent plate boundaries.Converging plate boundaries are classified into two types of activities.First is the subduction boundary where the oceanic lithosphere is pressured beneath a continental plate or oceanic plate thus it overrides the other plate then slowly directed to the mantle where it will become a magma. Second is the collisional boundary where earthquakes occur because of the continental crust squeezed together then plates are pushed upwards.Reverse faults are correlated to earthquakes with magnitude of 8 or more.Hence, earthquakes of magnitude 8 or more are considered powerful and mega thrust earthquakes.</span>

Some members of the Euglenids are photosynthetic, yet they will lose their photosynthetic pigment if left in the dark. True or F
irga5000 [103]

A) Some members of the Euglenoids lose their photosynthetic pigment when left in Dark : TRUE

B )The loss of photosynthetic pigment in Euglenids stored in the dark is permanent : False

<h3>What are Euglenas</h3>

Euglenas are unicellular organisms belonging to the kingdom Protista, when kept in the dark for too long Euglenoids begin to lose their chlorophyll. As it loses its chlorophyll it becomes unable to produce its own food and starts consuming bacterias within its habitat.

The loss of chlorophyll in Euglenids can be regained after it is been exposed to sunlight and allowed  to grow exponentially for several weeks.

Hence we can conclude that  Some members of the Euglenoids lose their photosynthetic pigment when left in Dark : TRUE  while The loss of photosynthetic pigment in Euglenids stored in the dark is permanent : False
