Homework Help: Life prefers to use glucose over other sugars

  1. Jul 10, 2008 #1
    We learned that life prefers to use glucose over other sugars (catabolite repression).

    1) Why is glucose preferred?

    2) Why do sperm use fructose instead of glucose?

    Re: Glucose/Fructose

    Hmm I know that fructose is metabolized without insulin...is this for a bio class or for an ochem class?
