Photorespiration limits casualty products of light reactions
that build up in the absence of the Calvin cycle. In many plants,
photorespiration is a problem because on a hot, dry day it can drain as much as
50% of the carbon fixed by the Calvin cycle. The closing of stomata reduces access to CO2
and causes O2 to build up. These conditions favor a seemingly not useful process
called photorespiration. In most plants
(C3 plants), initial fixation of CO2, via rubisco, forms a three-carbon
compound. In photorespiration, rubisco
adds O2 instead of CO2 in the Calvin cycle. Photorespiration eats up O2 and
organic fuel and releases CO2 without producing ATP or sugar. Photorespiration
can evolve relic because rubisco first evolved at a time when the atmosphere
had far less O2 and more CO2.

A fracture in the shaft of a bone would be a breaking the diaphysis.(dia- through, physis=growth). Diaphysis or shafts forms the long axis of the bone.
Diaphysis is the main or mid section of a long bone. It is made up of the cortical bone and usually contains bone marrow and adipose tissue. It is a middle tubular part composed of compact bone which surrounds a central marrow cavity which contains red or yellow marrow.
