Answer:
In the portion of the cell membrane shown in the diagram, the arrow indicates the process of active transport.
Explanation:
Active transport is one of the mechanisms of transmembrane transport, which involves the use of energy. The diagram (see image) shows the hydrogen (H⁺) output from the cytoplasm to the extracellular space, through an H⁺ pump —consuming ATP— which represents an active transport process.
The hydrophobic nature of the cell membrane prevents the free passage of hydrosoluble elements or ions, as H⁺, so they require the use of active transport to pass through it.
The other options presented are not correct, because
- <u><em>Respiration</em></u><em> is a process that occurs in the mitochondria.</em>
- <u><em>Diffusion</em></u><em> is a passive transport process that does not require energy.</em>
- <u><em>Cellular </em></u><em>recognition depends on membrane proteins that act as specific receptors.</em>
