Question

why is the process that takes place in mitochondria often describe as being the opposite of the process that takes place in a chloroplast?

Chloroplasts produce ATP. Mitochondria consune ATP in the production of protines.

The mitochondria
are NOT the site of protein synthesis.
They are the power plants of the cell that produce ATP made from glucose (which may have come from the chloroplasts).
