Question

1) Biochemical pathway and the production of molecules

In a biochemical pathway, a molecule that contains a single carbon atom is combined with an other molecule that has a 5-carbon backbone. This results in the formation of a 6-carbon molecule that is so unstable it breaks immediately into two, 3-carbon molecules. These 3-carbon molecules are subsequently recombined to synthesize larger molecular components of the biochemical pathway. What can be said about this series of events? Check all that apply.

Check All That Apply

A: The 6-carbon molecule is insignificant and unnecessary.The 6-carbon molecule is insignificant and unnecessary.

B: The 6-carbon molecule is an important intermediate molecule.The 6-carbon molecule is an important intermediate molecule.

C: Catabolism has been utilized to generate molecular building blocks.Catabolism has been utilized to generate molecular building blocks.

D: Anabolism has been utilized to generate molecular building blocks.Anabolism has been utilized to generate molecular building blocks.

Drag the correct word from the left into the sentence on the right to complete each sentence. reduced In anabolic reactions, NADH and ATP are consumed In catabolic reactions, NADH and ATP are oxidized In the reaction Pyruvate NADH->Lactate NAD, pyruvate is being synthesized In the reaction Pyruvate+NADH >Lactate+ NAD, NADH is being produced
