Question

A protein with quaternary structure described as alpha_3beta_4 would be a homoheptamer heteroheptamer heterodimer homodimer homotrimer In the biosynthesis of Vitamin C, the last step involves the oxidation of two sulfhydryl groups adjacent carbon atoms methionine ATP proline Applying Zaitsev's rule to the intramolecular dehydration of trans-2- methylcyclopentanol would result in what major product? 1 -methylcyclopentanol 1- methyl 2-cyclopentanol 2-methylcydopenlanol 3-methylcyclopentanol a 3* alcohol Identify the list containing exactly one fat soluble vitamin A, C, D. E A, E, B_2, B_12 B_2, C, B_1 A B_2, C, A, K A, B_1, D, Lipoic acid What is the number of amino acids that contain either 5 or 6 carbon atoms? 3 4 7 10 12 The iron-sulfur clusters found in the electron transport chain complexes are usually held by what amino acid? cysteine histidine methionine tyrosine serine Translate the following mRNA into protein primary structure (list the I letter abbreviations). (Use the genetic code shown.) MINGLE MINCE MIRAGE MIST MINERALISED The four classical cardinal signs of inflammation were first described by Aulus Cornelius Celsus in the first century and include all EXCEPT swelling redness pain bad smell heat Triacylglycerols can undergo all of the following reactions EXCEPT saponification hydrolysis dehydration oxidation hydrogenation Complete oxidation (by O_2) of fatty acid (20:4Delta^6, 9, 12, 15) results in what monocarboxylic acid? propanedioic acid ethanoic acid ethanoic acid pentanoic acid hexanoic acid

Explanation / Answer

61. B

Protein complexes with alternating and subunits are hetero-oligomeric. Hence, 34 would be heteroheptamer.
