Which of the following molecules (gases) was thought to have been important in the formation of the Earth's earli est atmosphere? a) CHa, b) CO, c) NH3, d)H,0,el) all of these because they dissolved into the first oceans to form more complex molecules. 9. A solution that has a Ph of 2.0 is: a) a base, b) n 10. DNA and RNA are polymers consisting of monomers called a) amino acids b) disaccharides c) NaNe d) nucleic acids e) nucleotides 1. When amino acids are joined by the formation of peptide bonds, a molecule of . 2 _ is producedVater b) cartbon cj methane d) chitn eutral, c) neutral if H is added to H:0,d) an acid, e) none of these are true e macromolecule that can bind to deoxyribose nucleotides and to amino acids is a) gl NA c) Hormones d) Proteins e) DNA 13 What are the four nitrogenous bases found in RNA?,a adenine, thymine, cytosine, guanine b) alanine, tryptophan, cysteine, glycine adenine, guanine, cytosine, uracil d) alanine, guano, valine and tyrosine, e) none are correct 14. Different amino acids are distinguished by a) the composition (structure) of their side chains, or "R-groups" b) the location of their carboxy group c) the location of adenine, thymine, cytosine, guanine R groups d) the repeating N cC structure of the chain, e) none of these. 5 Within the theory of Chemical Evolution, polypeptide molecules have the potential for great biological importance because a) the 20 potential monomers are connected in long, chains, b) their specific shapes enables polypeptides to specifically bind other molecules that have unique shapes, c) The shape of each polypeptide is related to the types of 'R' groups, d) Small changes in the sequence of amino acids change the shape of the polypeptide All are true. 6Given your understanding of Chemical Evolution what would cause the formation of the polysaccharide, glycogen, to form in a micelle? 2) High amounts of polypeptides Pigh glucose, c) high chitin d) high cellulose e) all are about the same. the functional importance of the complex shapes of Nucleic acids is related to the: a) 'R groups, b) repeating N-C-C-N-C-C part of the molecular chain, c) polar properties of fatty acidsfaNitrogenous bases bound to the Phosphate, e) All are true.
Explanation / Answer
ques. number 5) correct answer is (C)
that is, glucose + 2 fatty acids + phosphate
explaination
structure of phospholipid molecule generally consists of 2 hydrophobic fatty acids , and a hyphillic phosphate group.,
and both these component are joined by glucose molecule.
