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 of transports

≪Propose a reaction mechanism using the criteria presented in the lesson‚ with the third step as the rate-determining step. Hypothetical reaction: A + 2B + 4C ---> 2D + E The rate law has been determined to be [B]^1[C]^2≫ I had prepared the material below before I received your criteria. As you know‚ each step in a reaction mechanism is an elementary step. Each step is characterized by its molecularity. A step could be unimolecular‚ as in A → B or A → B + C It could be bimolecular as in 2A → B +

particles‚ mucus clearance is an essential mechanism to remove the foreign particles‚ such as dust‚ bacteria‚ viruses and other potential pathogens‚ and to keep our airways and lungs clean and free of obstruction. An important mechanism for clearing mucus involves moving water across the membrane‚ out of the cell‚ into the mucus. This movement of water is a result of chloride and sodium transport across the membrane. This method‚ along with other mechanisms is what ensures fluidity of the mucus‚ resulting

Non-Specific Mechanisms - Endothelial Factors a) Smoothness of Endothelial Lining prevents Platelet‚ adhesion and Extension of clot into the Blood Vessels. b) Negatively Charged Particles present over the lining of the endothelial repels the clotting factors ( Protein Anions ) i.e Prevents Clotting - Velocity of Circulation - If Decreased - Leads to clotting 2.

Arndt’s study implies‚ even if a membership in a particular group is important‚ if it affects their self-esteem; they are likely to distance themselves from that particular group‚ especially if mortality is induced. This suggests that people are more focused on self-esteem than belonging to a group. It would be interesting to see if the extent of group identification contributes the disengagement of a particular group. For example‚ the difference between people who were raised highly accustomed to
