Question 26

5 / 5 pts

(Short response) Explain the common similarity in all prokaryotic and eukaryotic cells. Explain the similarity in at least two sentences. The fundamental similarity is that each cell type has a plasma membrane that separates life from non-life. The plasma membrane acts as a barrier to most molecules but does have proteins that permit select molecules to cross via proteins (transporters). The plasma membrane permits the cell to have a different composition of molecules inside the cell than out and defines a space for life to occur.

Question 27

5 / 5 pts (Short response) Would a scientist be more likely to find an element such as O in a biomolecule, or W? Explain which she would more likely find in a biological molecule and give specific physical/chemical properties. She would more likely find O. Smaller elements are preferred. In the case of O, it is found in water, so it would be highly concentrated. Smaller elements with smaller atomic shells are favored because they can form stable covalent bonds. Strong bonds form by significant overlap of atoms, such as carbon and hydrogen permitting them to share electrons. The bond that forms requires a substantial amount of energy to break, which allows the bonds to withstand insults, such as mechanical and thermal stresses. This bond strength is good news for living organisms. Stable bonds allow cells to form, hair to grow, and skin to protect against abrasion. Larger elements, such as W, tend to form ionic compounds–not covalent.

Question 28

5 / 5 pts (Short response) Describe at least three properties of carbon that permit it to be the basis of life.

  1. Carbon can form strong covalent bonds with a variety of different elements. 2. Besides, carbon can form double and triple bonds with other

Question 29

5 / 5 pts (Short response) What the definition of inorganic chemistry? How does it differ from organic chemistry? Inorganic chemistry is the study of all other elements, but carbon. Organic chemistry is the study of carbon-based compounds both in living and non- living organisms. There is no need to have separate sub-disciples for organic and inorganic chemistry, but for historical and organizational reasons, the difference exists. (Short response) Biochemists study the communication within and among organisms. According to the module, what are two other aspects of living organisms that biochemists study? In the module, biochemists also study the structure and function of biomolecules and the chemical reactions of organisms.
