Answer:
I’m in a good mood today, so here’s the response
Explanation:
In the segment of the cell membrane depicted in the diagram, the arrow illustrates active transport.
Explanation:
Active transport refers to one of the methods of transmembrane transport, which necessitates energy usage. The image shows the movement of hydrogen ions (H⁺) from the cytoplasm to the external environment via an H⁺ pump — requiring ATP — illustrating an active transport mechanism.
Due to the hydrophobic characteristics of the cell membrane, ions or hydrosoluble substances like H⁺ cannot pass freely, thus requiring active transport to cross the barrier.
The other alternatives provided are incorrect because
Respiration occurs within mitochondria.
Diffusion is a type of passive transport that does not use energy.
Cellular recognition relies on membrane proteins serving as specific receptors.
