    what is the difference in plant hormones and human hormones?
    plant hormones:
    produced through out the plant
    local cells and tissues are targeted


    human hormones:
    regulated by the CNS
    specific effects
    specified target

    the hormones could bind to DNA at the start of a gene, and then act as an activator or a repressor by either increasing or decreasing the rate of transcription

    ooh whats the answer to that? Is it something like BAT controls temperature to keep it cold enough for the fat stores, so then the stores could be used to release glucose energy and lower body fat whenever energy input is lower than energy output?

    remember the equation "ventilation rate = breathing rate x tidal volume" rework that to your satisfaction for every question regarding that ****

    Im not really sure but i was thinking something along..

    High calorie fat or cold temperatures stimulate the SNS
    The SNS secretes noradrenaline
    BAT cells multiply and release T3 locally
    T3 stimulates production of UCP-1
    UCP-1 disrupts the respiration bu uncoupling electron transfer from ATP production
    Energy is lost as heat so more glucose and fatty acids needed to provide for the metabolic process.
    Need to eat more to get the same amount og energy. And the energy is lost as heat instead of for ATP synthesis
