QUESTION 24 The "energy carrier" ATP is an example of a(n): deoxyribonucleoside triphosphate. O dinucleotide. peptide. O ribonucleotide. ribonucleoside triphosphate.

QUESTION 26 Which of these reagents is commonly used to determine the number of polypeptides in a protein? dansyl chloride 2-mercaptoethanol (B-ME) DEAE cyanogen bromide iodoacetate O O O O

Question 12 Which of the following best explains the relatively more complex folded structure that an RNA molecule assumes? A B с D RNA molecules do not contain a pentose sugar in their backbone, which allows them to be more structurally flexible. RNA molecules contain the nitrogenous base uracil, which can pair with several other ni- trogenous bases in the RNA molecule. RNA molecules contain negatively charged phosphate groups in their backbone, which allows the molecule to bend into complex shapes. RNA molecules are made of only four types of nucleotides, which allows their nitroge- nous base to pair more readily.

What molecule pushes ADP and phosphate together to build most of the ATP created during aerobic respiration? O Spinning ATP synthase channels in the inner mitochondrial membrane O Oxygen gas in the mitochondrial matrix O Electron Transport proteins in the cell cytosol O NADH
