Outline the roles of membrane at the surface of the cell The plasma membrane encloses the cell‚ defines it boundaries and maintains the essential differences between the cytosol and the extra-cellular environment. The separation of the internal and external environment maintains a constant internal environment which is essential for the cell to function efficiently. Membrane receptors can interact with specific molecules corresponding to stimuli such as hormones to generate a signal cascade which

ACTIVITY ONE- Cell Transport Mechanisms and Permeability: Simulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. Molecular weight affects the rate of diffusion because the bigger the size of the molecule the longer it will take to diffuse. Membrane size is another variable that affects the rate of diffusion because if the membrane’s pores are small it will take molecules longer to diffuse though it than if the pores were larger. Also‚ membrane thickness

In this essay I improved in the areas of presenting two arguments. When writing an essay that argues a certain point‚ it is important to present both sides of the argument in order to give importance to your thoughts and final point.
