- Which of the following statements about active processes of membrane transport is true? cellular energy is required substances move against its concentration gradient all requires the aid of proteins during transport a and b a, b, and cWhat is another way to answer this question Describe various examples of active transport. How is active transport different from passive transport? Without saying this: Active transport is when cells move against the flow/ concentration gradient, moving from low concentrations to high concentrations. Because of this, active transport requires ATP to work. Passive transport is different because it doesn't use much energy and moves from high concentration to a low concentration. Some examples of active transport are the Sodium-potassium pump ( the most well known one) where it takes sodium ions and pumps them outside of the membrane to let in potassium ions. Another one in plants is when a plant receives ions from the soil. The soil has a much lower concentration of ions than a plants root does, so ions have to move against the concentration gradient. Endocytosis and exocytosis are also forms of active transport. Where cells engulf its self around large molecules to bring…Which of those ions do not have specific pumps in membrane? Select one: a. K O b. H O c. CI d. Na
