@KonradRudolph - the body always expends some energy, but the energy the body uses while sleeping is a fraction of the energy it takes to stay awake/hunt/etc.

comment How can I measure bacterial alkaline phosphatase activity?
Thank you, but I don't think I can imitate the kit - they don't share the components of the buffers. It did give me some idea of how the protocol is done, so thank you.
