In endoplasmic reticulum, many folds leads to an increase in surface area for ribosomes to attach which allows for protein synthesis to occur at an efficient rate.
mitochondria has two membrane,
It has an inner membrane which is folded inside the other. The fold create cristae, which is the site for a portion of cellular respiration.
The folds also enables a large surface area that makes chemical process to occur in an efficient way.
Homeostasis is maintained by the respiratory system in two ways: gas exchange and regulation of blood pH. Gas exchange is performed by the lungs by eliminating carbon dioxide, a waste product given off by cellular respiration.
