Unformatted text preview: ~ 291 mOsm ~290 mOsm ~ 290 mOsm * Very important note : The concentration of Ca ++ is very low in the cytosol (for the difference between cytosol and cytoplasm, see Fig. 3-5). However, smooth endoplasmic reticulum stores Ca ++ and has, therefore, a very high concentration of Ca ++ (see Fig. 3-12). In muscle, smooth endoplasmic reticulum is modified and is called sarcoplasmic reticulum, which also has a very high concentration of Ca ++ (see Fig. 9-12)....
