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

This makes it difficult for the air to move in and out of the lungs causing a continuously whistle sound when you breathe‚ chest tightness‚ shortness of breath and coughing‚ especially at night. Not every person with asthma has the same

Enzymes are biologic polymers that catalyze the chemical reactions that make life as we know it possible. The presence and maintenance of a complete and balanced set of enzymes is essential for the breakdown of nutrients to supply energy and chemical building blocks; the assembly of those building blocks into proteins‚ DNA‚ membranes‚ cells‚ and tissues; and the harnessing of energy to power cell motility‚ neural function‚ and muscle contraction. With the exception of catalytic RNA molecules‚ or
