Humans produce sweat as a cooling mechanism to maintain a stable internal temperature. Which of the following best explains how the properties of water contribute to this physiological process? - ANSWER The high heat of vaporization of water allows the body to remove excess heat through a phase change of water from liquid to gas A student placed a semipermeable membrane inside a U-shaped channel with two chambers, as shown. The membrane permits the movement of water but not salt. The...

Describe the function of the E1, E2, and E3 enzymes in the ubiquitinating system. Why are there ~500 E3 genes in the human genome but only two E1 genes? correct answers E1 enzymes attached ubiquitin to E2 enzymes, E2 enzymes conjugate ubiquitin to target proteins, and E3 enzymes recognize target proteins and facilitate ubiquitination by interacting directly with E2-ubiquitin and the target protein. E3 proteins must recognize a large number of target proteins, and thus there are hundreds of diffe...
