Look at the following statement. What word completes the second gap? Substances move by active transport from an area where they are __________ concentrated to an area where they are __________ concentrated
The answer is MORE
Explanation:
Substances move from one position to another in living systems. This movement of substances can either be passive (without energy) or active (require energy). Active transport of substances involves the movement of substances against their concentration gradient.
Ideally, substances move naturally from an area they are more concentrated to an area they are less concentrated but in active transport, the opposite occurs i.e. substances move from area that they are less concentrated to one that they are more concentrated, which is going up against the normal concentration slope/gradient. Due to this, energy in form of ATP is usually required by the cell to perform active transport unlike passive transport that occurs without energy input.
Exanples of active transport in living cells are exocytosis and endocytosis in some organisms. Based on this explanation, the first gap will be LESS while the second gap will be MORE.
In active transport, materials move from an area of high concentration to an area of lower concentration (goes down the concentration gradient) and it requires or uses energy in the form of ATP (adenosine triphosphate)
