Buddha puja (offering) defines as giving with respect, in here from which cetasikas the respect is made of?

When we offer something like food to a buddha statue (a buddha puja) the buddha statue has no benefit from it.. But we offer it (buddha puja) as a respect to buddha and gain merits.. so the buddha puja defines as giving with respect.. According to abhidhamma alobha cetasika, is the basic reason for giving ..like that I think saddha, is the basic reason for respect here.. if so what cetasika is the respect (or from what cetasikas the respect is made of?) in this occasion..
