N the early 1900's a scientist hypothesized a link between DNA and the production of proteins in the cytoplasm. However, the fac

t that DNA could not be found outside the nucleus led scientists to belive that another substance was also involved in the synthesis of protein in the cytoplasm. In the 1940s scientists performed an experiement that ultimately identified the site of protein synthesis. They also identified the molecule respnsible for transporting information from the nucleus to the site of protein synthesis. What was this newly identified molecule?
Your answer:
How does the cytoplasm synthesize protein?
How does DNA replicate in the cytoplasm to make genes?
What molecule transports information from the nucleus to the cytoplasm to make protein?

The plasma membrane or the cell membrane is the one that protects the cytoplasm of a cell. It is mostly composed of lipids and proteins. It has a phospholipid bilayer that controls the entering and exiting of molecules in the cell and at the same time, provides protection for the cell or plasma membrane. It has polar head and a nonpolar tail. Proteins embedded within the phospholipid bilayer have the same function of the plasma membrane that includes selective transport. The phospholipid bilayer consists mainly of the lipid molecules.

Answer:

Option 4 - Calcium

Explanation:

The <em>divalent cation </em>called <em>calcium</em> is needed to provide additional support to the bone matrix.

Calcium is considered one of the most <em>important components</em> in bone development. It helps in the formation as well as maintenance of bone. During the modeling and remodeling process of bones, calcium facilitates the formation of <em>semi-hard new tissues</em> which leads to the formation of new bone which is very hard.

Due to this reason, calcium is needed to create extra bone matrix support.

Why is Catalase important to the body?
oksian1 [2.3K]

Answer:

Catalase behaves as a catalyst for the conversion of hydrogen peroxide into water and oxygen.

Explanation:

Catalase is an antioxidant enzyme that plays a very important role in the protection against oxidative damage by breaking down hydrogen peroxide. It is a very highly conserved enzyme that has been identified from numerous species including bacteria, fungi, plants and animals.

Catalase has one of the highest turnover numbers for all known enzymes (40,000,000 molecules/second). This high rate shows an importance for the enzymes capability for detoxifying hydrogen peroxide and preventing the formation of carbon dioxide bubbles in the blood.
