Answer:

a. 40%

Explanation:

The continental crust covers <u>40%</u> of the Earth's surface.

Chaperone proteins or chaperones assist in the proper folding of proteins. Explain the process.
oksian1 [2.3K]

Proteostasis is mediated by chaperone proteins and protease systems, together with cellular clearance mechanisms such as autophagy and lysosomal degradation.

Chaperone proteins control assembly and inaccurate folding by binding to and stabilizing partly or completely unfolded protein polypeptides till the polypeptide chain is completely synthesized. Chaperone proteins also confirm the stability of unfolded polypeptide chains as they are being translocated into the subcellular organelles.
