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...

How is malonyl-CoA formed? correct answer: Carboxylation of acetyl-CoA to form malonyl-CoA requires two steps (both use acetyl-CoA carboxylase). 1. The enzyme, complexed with biotin, acquires CO2 from HCO3 - a. Requires 1 ATP 2. The carbon is transferred to acetyl-CoA to form malonyl-CoA The overall reaction is irreversible and commits the molecule to fatty acid synthesis. Phosphate is added to HCO3 - and then removed so that biotin-carboxylase can grab the carbon. The carbon is donated to...
