Because it’s time consuming and money consuming to observe from space so models are required
A macrophage may engulf a pathogen by endocytosis, which involves the reorganization of actin microfilaments in the membrane and microtubules in the cytoskeleton.
<h3>What is endocytosis?</h3>
Endocytosis is a cellular process by which a cell can absorb materials from the surrounding medium, such as viruses and bacteria in the case of macrophages.
Microfilaments and microtubules are proteins that form part of the cytoskeleton and dynamic conformational changes of them are associated with the cytoskeletal rearregement during the phagocytic process.
The actin microfilaments in the membrane and microtubules in the cytoskeleton form part of the process of endocytosis because they need to reorganize during cell movement.
In conclusion, a macrophage may engulf a pathogen by endocytosis, which involves the reorganization of actin microfilaments in the membrane and microtubules in the cytoskeleton.
