There are two types of cell transport mechanisms. These types of transports are passive and active transport. The difference between active and passive is that passive does not require energy and active does require energy. The reason passive does not require energy is because it travels down a concentration gradient. On a concentration gradient molecules naturally move from high to low concentration. In active transport‚ molecules move from low to high concentration. There are three different types

Activity 1: Stimulating Dialysis (Simple Diffusion) 1. Describe two variables that affect the rate of diffusion. The two variables that affect the rate of diffusion are: • The composition of the lipid layer‚ this content varies from tissue to tissue. For example kidney tissues have a high cholesterol content which makes them impermeable to water. • The size of the molecule‚ the larger the molecule the slower the rate of diffusion. 2. Why do you think the urea was not able to diffuse

Cell Transport Mechanisms Essay There are two methods of moving molecules across the cell membrane‚ passive transport and active transport. Passive transport doesn’t use energy‚ while active transport does use energy. Passive transport allows molecules to move on their own according to natural laws of physics. The three types of passive transport mechanisms include diffusion‚ osmosis‚ and facilitated diffusion. Diffusion is the movement of materials from an area of most concentrated to

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
