Question

question 13 2 pts a biochemist is analyzing an aqueous solution of a pure unidentified macromolecule that she isolated from the cytosolic fraction of plant cells. she determined that the macromolecule is probably dna from chloroplasts and mitochondria by adding an enzyme that catalyzed the destruction of the macromolecule. the enzyme most likely broke which type of bonds? glycosidic phosphodiester peptide question 14 2 pts what process makes bread dough rise? oxidative phosphorylation glycolysis fermentation

Explanation:

For Question 13, DNA is composed of nucleotides linked by phosphodiester bonds. Enzymes that break down DNA act on these bonds. Glycosidic bonds are in carbohydrates and peptide bonds are in proteins.
For Question 14, yeast in bread - dough undergoes fermentation. Fermentation produces carbon - dioxide gas which causes the dough to rise. Oxidative phosphorylation is part of cellular respiration in mitochondria and glycolysis is the breakdown of glucose without producing the gas that makes dough rise.

Answer:

Question 13: B. phosphodiester
Question 14: C. fermentation
