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

Discuss the structure of the plasma membrane and explain the process of active and passive transport through the membrane. The plasma membrane is made up of proteins that form pores and channels‚ carbohydrate molecules that are used for cell recognition and cholesterol to provide membrane stability. Phospholipid molecules are the most abundant component found in the plasma membrane. Phospholipids molecules are composed of a phosphate head and a lipid tail; the structure of a cell membrane

The Science of Transportation: Ancient World: The Wheel: • How do they work? Wheels work by rolling along a surface. The curved surface of the wheel reduces the friction between the two surfaces due to a decrease in surface area. With less friction it is much easier to move an object. This is because rolling friction is much weaker than sliding friction. • How did they come to be? The wheel was invented in prehistoric times; as the oldest example of a wheel yet found is from the region of
