Which of the following conditions would lead to a 'right-shift' in the oxygen-dissociation curve, facilitating oxygen unloading in tissues?
- Binding of carbon monoxide (CO) to the heme.
- Decreased levels of 2,3-BPG in the erythrocyte
- Decreased temperature together with an increased blood pH
- Increased partial pressure of CO_2 and decreased pH
