Biological Differences Between Active Transportation And Passive Transport
Active transport and Passive transport are biological functions that carry water, nutrients, and oxygen into cells and for the removal of waste in the cell. Active transport utilizes chemical energy to move substances from lower concentrations to higher concentrations. Whereas Passive transport moves substances from areas of high concentration to areas of low concentration, and it does not need to use energy. Active transport uses a chemical called ATP as its energy source in its functions. Without ATP or energy the Active transport process would not work. It needs this energy because it is pumping substances inside of the cell against the concentration gradient. This process disrupts the equilibrium caused by diffusion. Active transport is

Primary active transport utilizes transmembrane proteins that can recognize the presence of certain substances that need to be transported into the cell. Primary active transport acts as a pump to move the substances. Secondary active transport utilizes pore-forming proteins that create channels in the membranes to force biochemicals through with an electromagnetic gradient. Usually the energy for secondary active transport is obtained through moving other substances down the concentration gradient simultaneously. Passive transport allows substances to move down the concentration gradient. This means the substances move from high concentrations to low concentrations. This process helps keep equilibrium in cells. Passive transport also doesn't need any energy to work because it uses diffusion to move the substances through a selectively permeable membrane. Passive transport helps to maintain equilibrium with the smaller substances. This is because the smaller particles diffuse easier because of their small size and can easily float through small spaces. Some examples of these particles are, carbon dioxide, water, oxygen, and anything soluble. Once the equilibrium is fully established there is no longer net movement between the inside of the cell and the outside of the
