response (EC50) occurred at a bath concentration of 2.74 x 10-8 M. The Hill coefficient of this curve was 1.237‚ indicating positive cooperativity. A representation of the isotonic contractions of the ileum can be seen in Appendix‚ Figures 1 and 2. Figure 2 illustrates the response of the Guinea Pig ileum through isotonic contractions when a dose of ACh is added into the organ bath with a competitive antagonist. A relationship between response and bath concentration can be identified through the clear

The cell‚ which is the smallest unit of life‚ is surrounded by a plasma membrane. The plasma membrane functions somewhat like a wall‚ as it keeps the internal contents from the external environment. Just like a wall‚ the membrane is also somewhat permeable‚ except that the membrane takes a much more active role in determining what is allowed in to the cell and what is kept out. The plasma membrane is a very thin structure‚ which has some very important tasks. One of the main tasks that it performs

substances across a semipermeable membrane to gain a better understanding of how cells move materials across cell membranes. The experiment was designed to exhibit Brownian Motion; the random movement and tendency of particles of a substance to move from an area of greater concentration to lower concentration via diffusion until equilibrium has been attained. In addition to observing the passive process of diffusion‚ the experiment demonstrated how a semipermeable membrane will only allow certain substances

The treatment of the bones follow a rule‚ which is to put the broken pieces of the wrist back into place and not let it move‚ so they heal properly. There are various treatments for the distal radius fracture and they depend on certain circumstances. There are surgical and non-surgical treatments. A filled splint might be worn at first in order to straighten out the bones and supply the wrist to provide some relief from the initial pain

mosaic model of the cell membrane. What is the fluid mosaic model? The fluid mosaic model is a model conceived by S.J. Singer and Garth Nicolson in 1972 to describe the structural features of biological membranes. The membrane is described to be fluid because of its hydrophobic integral components such as lipids and membrane proteins that move laterally or sideways throughout the membrane. That means the membrane is not solid‚ but more like a ’fluid’. The membrane is depicted as mosaic because
