13 Multiple Choice 2 points Phosphoenolpyruvate moves across the inner mitochondrial membrane by: O The malate-aspartate shuttle Facilitated diffusion The pyruvate transporter An antiporter driven by protons leaving the matrix along their concentration gradient The PEP transporter 14 Multiple Choice 2 points Two ATP equivalents are required for: O Formation of the aminoacyl-tRNA only Attachment of the incoming amino acid residue to the nascent protein Formation of the aminoacyl-tRNA and for the addition of the attachment of the incoming amino acid residue to the nascent protein Recognition of the Shine-Dalgarno sequence and for attachment of the incoming amino acid residue to the nascent protein O Formation of the aminoacyl-tRNA and recognition of the Shine-Dalgarno sequence 15 Multiple Choice 2 points The pyruvate dehydrogenase complex and the o-ketoglutarate dehydrogenase complex are similar in that they: Use a swinging arm mechanism to keep products from diffusing away prior to the next step of the pathway Both catalyze substrate level phosphorylation reactions Catalyze reactions involving the same reaction substrates O Are both involved in the preparatory steps for the citric acid cycle O Both a total of six enzymes to fully convert substrates to products 16 Multiple Choice 3 points If the 3'-hydroxyl group is missing from a nucleotide: O That nucleotide can be inserted into the nascent strand, but further replication will not be possible The nucleotide with the missing 3'-OH group cannot be added to the nascent strand DNA replication will continue in the forward direction, but Okizaki fragments will not be synthesized DNA polymerase I will recognize and remove it O It will not affect DNA replication
