which of the following is not a reason why metabolic pathways proceed smoothly?
enzyme regulation of cellular chemical reactions
cellular chemical reactions are exergonic.
the use of energy carrier molecules to capture and transfer energy between reactions
coupling of endergonic and exergonic reactions

Explanation:

• Enzyme regulation ensures reactions occur at the right time and rate.
• Energy carrier molecules (like ATP) help transfer energy.
• Coupling endergonic (energy - requiring) and exergonic (energy - releasing) reactions allows for energy utilization.
• Not all cellular chemical reactions are exergonic. Some are endergonic and need energy input, which is provided by coupling with exergonic reactions.

Answer:

Cellular chemical reactions are exergonic.
