Active Transport Process Quiz

Active transport moves substances from a more dilute solution to a more concentrated solution against a concentration gradient. It requires energy from respiration and allows mineral ions to be absorbed into plant root hairs from very dilute solutions in the soil, which is essential for healthy plant growth.

Active transport allows sugar molecules to be absorbed from lower concentrations in the gut into the blood, which has a higher sugar concentration. This process is essential as sugar molecules are used for cell respiration.

Active transport plays a crucial role in maintaining the concentration of essential substances within cells and organisms, allowing for processes such as nutrient absorption and energy production. It enables the movement of substances against their concentration gradient, ensuring the necessary supply of nutrients and ions for various cellular and physiological functions.
