Regulated Cell Death Part A: Apoptotic Mechanisms. Jun Suzuki, Shigekazu Nagata, in Methods in Enzymology, 2014. Abstract. Phospholipids are asymmetrically distributed at plasma membrane in normal cells, and scrambled in various biological situations such as blood clotting and apoptotic cell death. Recent studies revealed that phospholipid …a) Solution A: 1.4% (m/v) starch. b) Solution B: 7.62% (m/v) starch. a) Solution A: 1.4% (m/v) starch (The water molecules actually move in both directions, but they move to a greater extent toward Solution B because it has a higher solute concentration than Solution A. The net movement of water molecules causes Solution A to decrease in volume ...
