Actually I have more problems with the term "light reactions" to
all the reactions involved in ATP and NADPH synthesis. The only true
reactions are the photochemical ones. All the others are dark
reactions - with
no direct light requirement at all.

BTW. In answer to the original question - infra-red radiation does not
drive the
photosynthetic reactions (and certainly not the Krebs cycle ...).
