Overall, four molecules of atp are produced by glycolysis. however, the products of glycolysis are two atp molecules, two pyruvate molecules, and two nadh molecules. the atp values do not match because select one: a. glucose metabolism is inefficient. b. glucose phosphate is formed from fructose phosphate. c. glucose is degraded to co2. d. two atp are invested in the process of glycolysis. e. none of the above

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.
