Active transport is the movement of particles against a concentration gradient, requiring energy from respiration, such as nutrient absorption in the gut.
Definição de transporte ativo: O movimento de partículas através de uma membrana contra o gradiente de concentração (baixa concentração para alta concentração) usando energia da respiração. Por exemplo, no sistema digestivo, onde às vezes a concentração de nutrientes no intestino é menor do que no sangue, mas ainda assim passa para o sangue para nos impedir de morrer de fome.

| Back | The movement of particles across a membrane against the concentration gradient (low concentration to high concentration) using energy from respiration. For example, in the digestive system where sometimes the concentration of nutrients in the gut is lower than in the blood but it still passes to the blood to stop us from starving. |
