Final answer:
Healthy cells near diseased cells undergoing apoptosis might die due to toxic byproducts like reactive oxygen species released from the dying cells. Apoptosis is often inhibited in cancer cells due to mutations, causing uncontrolled cell growth. Excessive toxic byproducts from cellular waste can also lead to cell death. Option C.
Step-by-step explanation:
When diseased animal cells produce molecules that initiate death cascades, a process known as apoptosis, it results in a controlled cellular self-destruction to prevent further damage to the organism.
However, neighboring healthy cells may also die due to several factors. One reason could be the toxic byproducts released by the dying cells, such as reactive oxygen species (ROS), that can harm nearby cells.
These ROS are highly reactive chemicals that can cause cellular and DNA damage, leading to dysfunction and cell death.
This is one way in which a diseased cell's apoptosis process might inadvertently affect surrounding healthy cells.
In another scenario, a failure of cancer cells to undergo apoptosis when exposed to an inducer can be explained by mutations that prevent signaling, loss of expression of apoptosis receptor, or overexpression of a growth factor that inhibits apoptosis.
Cancer cells often bypass the programmed cell death that keeps cell proliferation in check, leading to uncontrolled division and tumor growth.
When apoptosis is inhibited, cancer treatment might aim to restore this cell death process to prevent cancer proliferation.
It's also important to note that cells require energy to survive and excessive waste products or large undigested molecules can produce substances toxic to cells.
Such substances can lead to cell death if they disrupt the chemical balance or are excessively accumulated within or around cells.
Hence, the right answer is option C.
