Which statement best describes how the energy stored in atp is released to drive biochemical reactions? a. energy is released when the ribose sugar reacts with oxygen during aerobic respiration. b. energy is released when adenine is removed from ribose by dehydration synthesis. c. energy is released when a phosphate group is removed by hydrolysis.

According to the rna world hypothesis, rna acted as the genetic material and catalyzed reactions in ancient cells. what conclusion can you draw from this?               a.  this implies that dna and proteins aren't essential in cells today.    b.  this implies that rna can catalyze any chemical reaction that enzymes catalyze.    c.  this implies that if a cell has a problem with its dna, its rna can compensate for the damaged dna.    d.  this implies that dna and proteins evolved after rna.
