Oxygen may attack the double bonds of polyunsaturated fatty acids and convert them into which of the following harmful substances: a) carcinogens b) atherogens c) immune suppressants d) substances linked to the charges seen with aging e) AOTA If two (2) different types of atoms share electrons, we say that they have a(n): a) ionic bond b) covalent bond c) hydrogen bond d) ester bond e) NOTA 16. 17. Elements are chemical substances which cannot be broken down further into simpler components by ordinary chemical means? a) True b) False
Explanation / Answer
12.Correct answer is:c)aminoacids
Reason:Proteins are polymers of aminoacids and hence their hydrolysis will yield the monomers that make them i,e aminoacids.
13.Correct answer is:b) electrons
Reason:In an ionic bond, electrons are transferred from one atom to the other and the oppositely charged ions get attracted to each other to form a compound.
14.Correct answer is:a) stable
Reason:Outer shell with 8 electrons means the atom has noble gas configuration and hence it will be stable.
15.Correct answer is:e)AOTA
Reason: Oxidation of double bonds polyunsaturated fatty acids forms end products that might be carconogenic,atherogenic ,immune suppressants and cause ageing.
16. Correct answer is :b) covalent bond
Reason:Covalent bond is formed by atoms that share electron pairs between them.
17.The statement is a)TRUE.
Reason:Element cannot be broken down into simpler substances by any chemical means and examples include iron,gold,carbon etc.
