What is the mechanism of an aldehyde reacting with fehlings solution and tollens reagent?

I know it is oxidised to a carboxylic acid, but i want to know the mechanism.
Thank you.

We can't draw mechanisms/diagrams/pictures on this forum. I suggest you look at google. I'm sure there is on on the web. Try this site. I see some electrons being pushed. If this does'nt help use google.
