Answer:
The correct answer is option - phagocytosis.
Explanation:
The explained experiment is the pulse-chase experiment in this the cells that are involved are macrophages. Macrophages are the immunity cells that have a large number of the lysosomes for killing the pathogens enters in the cell brought into the cell through the process of phagocytosis.
Phagocytosis takes place with the help of the enzyme called hydrolytic enzyme that is synthesized in the endoplasmic reticulum and modified by Golgi and moves to the lysosome.
Thus, the correct answer is option - phagocytosis.
Answer:
The endomembrane system permits various functions of the eukaryotic cell to be compartmentalized (e.g., protein degradation occurs in the lysosome), allowing a higher degree of cell specialization. The system relies on dynamic interactions between different compartments, facilitated by vesicle trafficking between them.

Answer:
d. An enzyme will generally bind only one substrate.
Explanation:
Enzymes are the catalytic biomolecules. The enzymes have specific pockets called active sites. Substrates bind to these pockets of enzymes. The active site of an enzyme is compatible to allow a specific substrate to bind to it. This allows specificity to the enzymes and ensures that a specific enzyme binds to a particular substrate only. A substrate can bind to the active site of its enzyme, it can not bind to any other site of the enzyme. Moreover, substrate binding induces a conformation change in the active site of its enzyme to favor the binding of more substrate molecules.
