Energy Metabolism

  1. Sep 18, 2009 #1
    Is it safe to assume that catabolic reactions are always exergonic and anabolic reactions are always endergonic?

    Also, I had a question on energy metabolism. Since the mitochondria is where energy is stored, does that mean that metabolic (energy) pathways only occur in the mitochondria? Or is there some other place in the cell that it can be done? I had this question:
    Metabolic pathways ________________.

    are often organized as a multi-step sequence of reactions
    None of these.
    occur only in mitochondria
    only link smaller molecules together to create polymers
    always break down large molecules into smaller ones

    Would it be only occur in mitochondria?
