MAKE CONNECTIONS. Ø Peristalsis contributes to the locomotion of many annelids and to the movement of food in the digestive tract (see Concept 41.3). Using the muscles of your hand and a toothpaste tube as a model of peristalsis, how would your demonstration differ for the two processes?

Salmoneus dies.When a cell dies its plasma membrane becomes“leaky”;i.e.,it becomes permeable to ions that were unable to freely cross the membrane during life. Thus, after death, calcium ions leak across the sarcolemma of muscle fibers. This calcium leak causes rigor mortis, a temporary stiffness of the muscles after death. Apply your understanding of the mechanism of skeletal muscle contraction (specifically regarding events within muscle fibre) and explain the molecular basis of the phenomenon known as rigor mortis.
Problem. A 1-year-old child was admitted to the clinic with signs of damage to the muscles of the limbs and trunk. After the examination, carnitine deficiency in the muscles was revealed. Disruption of which transport process is the basis of this pathology? Explain the mechanism of this transport.
Work 2. The role of bile in digestion. Hepatic circulation of bile acids. Bile contains salts of bile acids, in particular, glycocholic and taurocholic. They reduce the surface tension of water and thereby contribute to the emulsification of fats, which facilitates the enzymatic cleavage of lipids. Further, in the of digestion, bile acids form micelles with lipids and their cleavage products, due to process Img. 19. Micelle structure which fats can be absorbed.
