We use hemoglobin and some animals use hemocyanin

We use hemoglobin and some animals use hemocyanin.

But is there a way to transport oxygen more efficiently than hemoglobin?

yeah

wind

yea just transfuse yourself with fetal blood every so often it has a higher affinity for O2. but adult rbc work because the lower affinity helps O2 come off easier

I used to work at the lysate facility pictured in OP's image. It's located in the Delmarva peninsula.

It fucking sucked. 5:30am-1:00pm. You get one piss break and then 30 minutes for lunch. Fuck Lonza corporation. I'm so glad my current lab is chill and everyone comes in at 10.

What's the point of a 30-minute lunch break when you finish at 1 PM?

If you wake up at 5:30 you generally eat lunch earlier than 1 pm.

Doesn't even seem that bad.

Except for the one piss break.

May be it would be human haemoglobin with modifications? Like, increased affinity to oxygen. But you`ll need better
antyoxidant defence, then.

The problem is everyone had to work at 'Lucy' speed because we had hundreds of crabs every day. I pipetted so much I developed carpal tunnel within a month.

are they killing those things?

I thought they were suppose to take a tiny amount of blood then release them. But they're being drained in OPs pic
