Answer:
The oxygen enters the bloodstream from the alveoli, tiny sacs in the lungs where gas exchange takes place (Figure below). The transfer of oxygen into the blood is through simple diffusion. ... While oxygen moves from the capillaries and into body cells, carbon dioxide moves from the cells into the capillaries.

Answer:  Protein folding and oligomerization
Explanation:
Binding immunoglobulin protein (BiP) is a vital protein present in humans essential for the translocation of secreted peptides. 
BiP is  a molecular chaperone which is present in lumen of ER (endoplasmic reticulum) which binds to the new protein and then translocat into the ER. The protein in ER is maintained under subsequent condition and important for protein folding and oligomerization (conversion of a  monomer or group of monomer into an oligomer). 
Several other functions of BiP are:
- ER translocation
- ER-associated degradation (ERAD)
- UPR pathway
Hence,  BiP is a chaperone, it is important for protein folding and oligomerization.
