If the calvin cycle slows down, what will happen to the rate of o2 production in ps ii, and why? if the calvin cycle slows down, what will happen to the rate of o2 production in ps ii, and why? o2 production will not change because the calvin cycle is a separate process from the light reactions. o2 production will speed up because not as much nadph will be used in the calvin cycle and so it will accumulate in the chloroplast. o2 production will slow down because the chloroplast will need less light energy to send to the calvin cycle. o2 production will slow down because less nadp+ will be regenerated in the calvin cycle. o2 production will not change because light energy will still be absorbed by the pigment molecules and excite the ps ii chlorophyll a pair.

hypoxemia refers to a below usual concentration of oxygen in the blood, mainly in the arteries. hypoxemia is an indication of an issue associated with circulation or breathing and may lead to various symptoms like shortness of breath.  

the condition is identified by determining the level of oxygen in the blood sample obtained from an artery. it can also be predicted by determining the oxygen saturation of the blood with the application of a pulse oximeter.  

the normal arterial oxygen is about 75 to 100 mm hg. the values underneath 60 mm hg is generally considered with the requirement for supplemental oxygen. the normal pulse oximeter readings generally range between 95 to 100 percent. the values under 90 percent are regarded as low.  

in the given case, the oxygen saturation is measured at 93 percent, hence, there is no need to administer oxygen, that is, one should withhold oxygen.
