Programmed cell suicide occurs when internal or external signals go through _____ processes.
Answer
a)reception
b)transduction
c)response
d)all of the above
The correct answer is d) all of the above. Programmed cell suicide, also known as apoptosis, is a controlled process that occurs when internal or external signals are received by the cell, undergo a series of cell signaling transduction processes, and eventually lead to the appropriate cellular response, which in this case is cell death.
To arrive at this answer, we can break down each option and see how they apply to the process of programmed cell suicide:
a) Reception: During apoptosis, internal or external signals are received by the cell. These signals may be chemical or environmental cues that trigger the cell to undergo apoptosis.
b) Transduction: Once the signals are received, they need to be transduced or transmitted within the cell. This involves a series of cell signaling pathways that amplify and relay the signal, resulting in a cascade of intracellular events that ultimately lead to cell death.
c) Response: The final step in programmed cell suicide is the cellular response, which is the actual initiation of the apoptotic process. This can involve changes in gene expression, activation of specific proteins, and ultimately, the dismantling and disposal of the cell.
Therefore, all of the above options are involved in the process of programmed cell suicide, making option d) the correct answer.
