Why is diffusion considered a type of passive transport? Select the correct answer below: A substance tends to move from an area of higher concentration to an area of lower concentration until the concentration is equal. Energy (in the form of ATP for cellular transport) is required for this transport. A substance tends to move from an area of higher concentration to an area of lower concentration until the concentration is equal. Energy is not required for this transport. A substance moves from an area of lower concentration to an area of higher concentration until the concentration is equal. Energy is not required for this transport. A substance tends to move from an area of lower concentration to an area of higher concentration until the concentration is equal. Energy (in the form of ATP for cellular transport) is required for this transport.
Why is simple diffusion and facilitated diffusion considered passive transport? a. The phospholipid bilayer is not selectively permeable when diffusion and facilitated diffusion take place b. ATP (energy) is needed for transport to occur c. A random motion causes a net movement of substances from areas of high to low concentration with no energy required for movement d. Substances are going against the concentration gradient (from low to high) e. Carriers and ion channels require energy to start any movement of ions or substances for both processes
