Polylysine and polyglutamate are two examples of synthetic polypeptides that can assume an α‑helical structure under appropriate conditions. identify which two synthetic polypeptides can form an α‑helix at the indicated ph values. polylysine at ph 13 polylysine at ph 7 polyglutamate at ph 13 polyglutamate at ph 2 polyglutamate at ph 7 polylysine at ph 2

Each of the following reactions is allowed to come to equilibrium and then the volume is changed as indicated. predict the effect (shift right, shift left, or no effect) of the indicated volume change. drag the appropriate items to their respective bins.co(g) + h2o(g) < => co2(g) + h2(g) (volume is decreased) pcl3(g) + cl2(g) < => pcl5(g) (volume is increased) caco3(s)< => cao(s) + co2(g) (volume is increased)
