The molecular weight of sperm whale myoglobin is 17.8 kDa. The myoglobin content of sperm whale muscle is about 80 g. kg^-1. In contrast, the myoglobin content of some human muscles is about 8 g. kg^-1. Required:
Compare the amounts of O2 bound to myoglobin in human muscle and in sperm whale muscle. Assume that the myoglobin is saturated with O2, and that the molecular weights of human and sperm whale myoglobin are the same. How much O2 is bound to myoglobin in human muscle?

What two fields of study provide the core information that is used to classify organisms?

The endoplasmic reticulum (er) is an organelle in some cells. in these cells, it is continuous with the nuclear membrane and forms a large part of the cell\'s total membrane. sort the phrases below as describing rough er, smooth er, both, or neither. note: if you answer any part of this question incorrectly, a single red x will appear indicating that one or more of the phrases are sorted incorrectly.1) found in prokaryites and uekaryotys2) involved in protein synthesis3) involve in lipid synthesis4) contains molecular chaperones in lumen5) bound with ribosomes6) involved in toxin or drug metabolism7) large systemot internnected tubules, vesicles, and sacs8) "packages" enzymes in vesicles for secretion.
