Answer:
The 5' cap is added to the mRNA as a means of protection from being degraded by enzymes in the cellular environment. Additionally. it helps with binding to the ribosome and subsequently translating it into a protein.
Explanation:
Moreover, it's only Polymerase II that has the ability to add the 5' cap and rRNA & tRNA are not transcribed by Polymerase II, only the mRNA is.
rRNA and tRNA have stable 3-Dimensional structures that protects it from being degraded by enzymes.
Hope that answers the question, have a great day!
<span>The epidermis is mainly a composition of cells called keratinocytes. Defensive cells are known as Langerhans cells and are one of the three types of specialized epidermal cells, The epidermis is bonded to the dermis. Hairs grow in the dermis and up to the epidermis. So, the dermis and the epidermis both have cells and hair. </span>
Answer:
The chemical reaction that represents the process of aerobic cell respiration is oxygen + glucose → water + carbon dioxide + energy
Explanation:
Cell respiration occurs in the mitochondria of eukaryotic cells and consists of a series of chemical reactions in which energy in the form of ATP molecules is obtained from a glucose molecule in the presence of oxygen.
<u>Glucose is the main energetic substrate</u> to be able to synthesize energy in the form of ATP, through oxidative phosphorylation. At the end of the process ATP is obtained as products, and as waste compounds water and carbon dioxide, which can be schematized in the following chemical reaction:
<em> C₆H₁₂O₆ + 6O₂ → 6H₂O + 6CO₂ + ATP ↑</em>
<em> Glucose + Oxygen → Water + Carbon dioxide + Energy ↑</em>
This reaction summarizes what happens in aerobic cellular breathing, which is necessary to synthesize energy for cellular functions.
The other reactions:
- <em>oxygen + water </em><em>→</em><em> glucose + lactose
</em>
- <em>glucose + lactose </em><em>→</em><em> oxygen + water
</em>
- <em>water + carbon dioxide + energy </em><em>→</em><em> oxygen + glucose</em>
<em>do not represent the components or the order of the reactions that occur in aerobic cell respiration</em>
