Question about 02 curves and such

Members don't see this ad.

I know that an elephant would have its curve to the left, and a mouse would have it to the right,

but what if for example the curve were to shift to the right? What would be the consequence then? How bout to the left?

Nvm..lol

The curve doesn't necessarily shift right or left for an elephant or mouse rather it normal curve is right or left of what is considered "normal"

Their size and metabolism is different thus a different curve.

The what causes the shifts for the mouse and the elephant is the same as with humans.

decrease pH the curve shift rights.

increase in pH it shifts left.

i think you misunderstood my question. I didnt say that the curve shifts to the left with the elephant and right for the mouse, i asked WHAT IF the curve were to shift to the left and/or right, what consequence would that have to the normal curve?

Ok first you need to change your heading on your question:

Are you asking about metabolism or are you talking about oxygen saturation. Because last time I checked rats and elephants have hemoglobin too to carry their oxygen so the O2 saturation curve would not be different. You are talking about a metabolism curve where it is measured by how much oxygen is being utilized by each organism.

A shift to the right would just mean that its metabolism would go up because of an increase in weight would mean an increase in breathing rate to refuel more cells. Vice versa with curve shifting to the right. Hopefully this straightens it out for you.

Basically, a shift right means the hemogoblin is going to drop off oxygen at a faster rate than the normal curve. This happens when you have a higher CO2 level, H+ level, more BPG (allosteric inhibiter for hemoglobin+oxygen).

A shift left, means that the hemogoblin has a higher affinity for oxygen, meaning that it will take up more oxygen than normal. Infants generally have this shift compared to their mother, as O2 will more readily diffuse into their blood cells. High altitude animals like llamas have this also.

In your example an elephant with somehow a permanently shifted curve left would be able to thrive at lower O2 levels compared to a "normal elephant". It's the opposite for the mouse.

For practical purposes, in a normal system, the shift to the right (temporarily) just lets you dump off more oxygen from hemoglobin to muscle tissues that are overworked (producing more H+)
