The diagrams above are illustrations of two different cells involved in biological processing in mammals. Study them and answer this question.
Which parts of P and Q fuse to complete the biological process?
Based on the diagrams, the answer is III and I.
The process involves the fusion of two cells: one with a large vesicle (cell P) and another with a smaller vesicle (cell Q). The fusion of these two cells allows the contents of the larger vesicle to be released and processed by the enzymes in the smaller vesicle.
In more detail, the process involves the fusion of the membrane of the large vesicle (III) with the membrane of the smaller vesicle (I). This fusion creates a pore that allows the contents of the large vesicle to enter the smaller vesicle. The enzymes in the smaller vesicle then process the contents of the large vesicle, and the resulting molecules are released from the smaller vesicle through its membrane (II).
Therefore, the parts of P and Q that fuse to complete the biological process are III and I.
