Answer:
According to the illustration of transmembrane transport mechanisms, the one representing an active transport mechanism is labeled with the letter C.
Step-by-step explanation:
The semipermeable nature of the cell membrane causes the passage of necessary substances from the cell to pass through various transmembrane transport mechanisms.
In the illustration, active transport is labeled with the letter C, which can be stated because:
- The passage of particles is against the concentration gradient.
- It requires energy to take place.
The type of transport in the illustration corresponds to primary active transport.
