Question 3

The function of a protein is fundamentally based on its shape. The shape of a protein is based on its amino acid sequence. A protein with 100 amino acids can theoretically fold into billions and billions of possible shapes, however, only one of these shapes is useful to carry out its function.

1) Briefly describe the four levels of protein folding and what influences each of them.

2) Devise a method for denaturing a given level of protein structure

3) What is a prion?

4) What is a chaperone protein?

5) Are proteins static or dynamic structures?

6) How many proteins are in the human body?

7) What is the largest protein in the human body?

Question 4

1) Which elements are liquid at room temperature?

2) What is the densest element?

4 / 4

3) What are the top 5 most abundant elements in the universe?

4) What are the top 5 most abundant elements in the Earth's Crust?

5) What are the top 5 most abundant elements in the human body?

6) What is the only letter not appearing in the periodic table?

7) How heavy is a mol of moles (the animal,use your favourite mole)?

8) What phase of matter is glass?

9) What is the most abundant biological molecule on the planet

10) Briefly describe a method of transmuting lead into gold

Answer 1

ans 3:
1. The four levels of protein structure are distinguished from one another by the degree of complexity in the polypeptide chain. A single protein molecule may contain one or more of the protein structure types: primary, secondary, tertiary, and quaternary structure.The four levels of protein structure are distinguished from one another by the degree of complexity in the polypeptide chain.

2.

Denaturation is a process in which proteins or nucleic acids lose the quaternary structure, tertiary structure, and secondary structure which is present in their native state, by application of some external stress or compound such as a strong acid or base, a concentrated inorganic salt, an organic solvent (e.g., alcohol or chloroform), radiation or heat.

3.Prions are misfolded proteins which characterize several fatal neurodegenerative diseases in animals and humans. It is not known what causes the normalprion protein to misfold; the abnormal 3-D structure is suspected to confer infectious properties. The wordprion derives from "proteinaceous infectious particle".

4.chaperones are proteins that assist the covalent folding or unfolding and the assembly or disassembly of other macromolecular structures. Chaperones are present when the macromolecules perform their normal biological functions and have correctly completed the processes of folding and/or assembly.

5.not strictly static

6. humans make at least 20,000 proteins

7.Titin

ans 4:

1. Bromine (Br) melts at 265.9 K
Mercury (Hg) melts at 234.32 K

2.osmium

3.hydrogen helium oxygen carbon neon

4.oxygen silicon aluminium iron calcium

5.oxygen carbon hydrogen nitrogen calcium

6. Q

7.A mole is also a type of burrowing mammal. There are a handful of types of moles, and some of them are truly horrifying.

8.Glass, however, is actually neither a liquid—supercooled or otherwise—nor a solid

9.cellulose

10.nuclear transmutation
