During apoptosis, cytochrome c is released from the mitochondria into the cytoplasm. This release is a key step in the activation of the apoptotic pathway. By detecting increases in cytoplasmic concentrations of cytochrome c, researchers can monitor the progression of apoptosis in real time. Various techniques, such as fluorescence microscopy or flow cytometry, can be employed to detect and quantify cytochrome c levels in the cytoplasm of live cells.
Measuring decreases in mitochondrial volume (Option B) or increases in mitochondrial concentrations of cytochrome c (Option C) are not typically used as direct indicators of apoptosis progression. Changes in mitochondrial volume or cytochrome c levels may occur during apoptosis, but they may not be as reliable or direct measures of apoptosis progression as the changes occurring in the cytoplasm.
Measuring increases in cytoplasmic volume (Option D) may not be a specific indicator of apoptosis since changes in cell volume can be influenced by various cellular processes unrelated to apoptosis.

Why option 'A' is the most promising avenue to develop the assay:
Detecting increases in cytoplasmic concentrations of cytochrome c:
- Cytochrome c is a protein released from mitochondria during apoptosis
- Increase in cytoplasmic cytochrome c indicates mitochondrial membrane permeabilization, a hallmark of apoptosis
- Detection of cytochrome c can provide real-time monitoring of apoptosis progression in live cells
- This method allows for direct observation of the initiation of apoptosis process
- Cytochrome c release is an early event in apoptosis, making it a sensitive marker for detecting cell death
By using this method, researchers can accurately measure the progression of apoptosis in live cells in real time, providing valuable insights into the dynamics of cell death processes.
