Active transport works in the opposite direction; it moves molecules from a low concentration to a high concentration, against the concentration gradient. This is the opposite of diffusion and osmosis. And because it is not the natural direction, energy from is required to make this work. Active transport is carried out by protein carriers. The protein carriers are within the cell membrane and they have a specific binding site for the exact molecule they are transporting. The substance binds to the protein carrier on the side that it is at low concentration. And using energy from respiration, the protein carrier releases the substance on the other side of the membrane - where it is already at a higher concentration.

Antibodies are the warriors inside our body. They are part of our immune system, recognising and fighting against bad foreign invaders, called antigens. Antibodies can bind to a broad range of antigens, and are produced by cells of the immune system, known as B-cells. To learn more about antibodies

Plants are extremely complex and diverse - there are thousands of species. In fact, there are probably somewhere around half a million different species. And these are just the ones we know about - there are no doubt many more that haven’t been fully discovered yet! It is estimated that 1 in 5, so
