Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]

A substance naturally moves from an area of higher to lower concentration. This is known as moving down the concentration gradient. It’s like rolling a ball downhill. The ball naturally rolls from a higher to lower position without any added energy. What type of energy is this referred as?

A	active transport
B	passivie transport
C	cellular transport

Explanation:

Detailed explanation-1: -Diffusion refers to the process by which molecules intermingle as a result of their kinetic energy of random motion. It is the net movement of molecules or atoms from a region of high concentration to a region of low concentration. This is also referred to as the movement of a substance down a concentration gradient.

Detailed explanation-2: -During active transport, substances move against the concentration gradient, from an area of low concentration to an area of high concentration. This process is “active” because it requires the use of energy (usually in the form of ATP). It is the opposite of passive transport.

Detailed explanation-3: -Section Summary Substances diffuse from areas of high concentration to areas of low concentration, and this process continues until the substance is evenly distributed in a system. In solutions of more than one substance, each type of molecule diffuses according to its own concentration gradient.

Detailed explanation-4: -Final answer: Movement of molecules from their higher concentration to their lower concentration is called diffusion.
