Large numbers of ribosomes are present in cells that specialize in producing ___________molecules

Biology
1 answer:
babunello [35]3 years ago
7 0

Answer:

Proteins.

Explanation:

Ribosomes are complex molecules present in all living cells, they are also called organelles. It serves as the site for protein synthesis. They can be gound freely in the cytoplasm or bound to certain organelles like the endoplasmic reticulum. They consist of two major structural components: the small ribosomal subunits, which read the mRNA, and the large subunits, which join amino acids to form a polypeptide chain.

There are 3 types of Ribosomes which are:

• Ribosomes link amino acids together in the order specified by messenger RNA (mRNA).

• Each unit also consist of ribosomal RNA (rRNA) molecules and a variety of ribosomal proteins.

• Transfer ribosomes (tRNA)

The photograph shows wild salmon. What makes wild salmon a renewable<br> resource?
AleksandrR [38]

The wild salmon has the capability of reproducing quickly, which makes wild salmon a renewable resource.

<h3>What do you mean by Renewable resources?</h3>

Renewable resources may be defined as those resources that are not exhausted and deliver endless energy.

Wild salmon can be taken as one of the chief sources of food that provides energy. This form of energy may lead to renewable energy because it is endless, as the reproduction rate of wild salmon is fast with  large clutch size.  

Therefore, the wild salmon has the capability of reproducing quickly, which makes wild salmon a renewable resource.

The brackets are indicating a(n) _____ bond.
Wittaler [7]

Answer:

The correct answer choice is B

Explanation:

We use these brackets in the first place to show the main molecule interconnection with other appendage molecules. For example, Ca(OH)2. The main molecule of calcium is joined with other two molecules and  brackets are showing interconnection simply. However, these brackets can't tell us about the orientation and position of bond in 3D space. We have to utilize stereo-chemistry for that...

<h2>Answer is option "A"</h2>

Explanation:

  • Oils and fats, which in science are called lipids, are known as amphipathic molecules. These molecules have two distinct ends to them: a water-loving (hydrophilic) side and a water-fearing (hydrophobic) side. While the hydrophilic sides of a lipid will associate with the water in a solution, the hydrophobic sides of the lipid all cluster together to 'hide' from the water. Lipids therefore cluster together and form spheres where the hydrophobic sides are in the center away from the water while the hydrophilic sides are on the outside, associating with the water.
  • The ability of the atoms within a group to form hydrogen bonds with the water molecules around them makes them hydrophilic. Oxygen and nitrogen atoms readily form hydrogen bonds with water molecules, so any organic molecules that have oxygen or nitrogen atoms bound to their carbon skeletons will be hydrophilic.
  • For example, if we take the molecule for cholesterol, we see the OH group on the left is hydrophilic and will form hydrogen bonds with water, while the ring structures, which only consist of hydrogen and carbon atoms, are hydrophobic and will not associate with the water.
  • There are many different kinds of lipids with different functions. Lets start by examining phospholipids, which compose the cell membranes of animals. They form lipid bilayers, with one set of hydrophilic heads facing the exterior of the cell membrane and the other set facing the interior (as you can see on the diagram on screen). The hydrophobic portions of the lipid bilayer - the lipid tails - face towards one another, which allows them to hide away from the water inside and outside of the cell.
  • So,the right answer is option A "amphipathic molecules".
