The correct option is d) active transport.
Explanation:
- Substances travel against the concentration gradient during active transport, from a low concentration location to a high concentration area. This process is considered "active" since it necessitates the usage of energy (usually in the form of ATP). It is the polar opposite of passive transportation.
- Active transport necessitates the aid of carrier proteins, which change shape when ATP is hydrolyzed.
- Animal and Human Examples of Active Transport are Pump for sodium-potassium (exchange of sodium and potassium ions across cell walls) ; Amino acids go through the human digestive tract and Glucose entering or exiting a cell.
