When a cell destroys itself through apoptosis, there is a specific process:
- The cell shrinks
- The DNA in the nucleus breaks down
- The mitochondria in the cell break down
- The cell breaks down into membrane-bound fragments
- The phospholipid, phosphatidylserine, appears on the surface
- Macrophages (and other phagocytic cells) have protein receptors which recognise phosphatidylserine
- Phosphatidylserine binds to these protein receptors, causing the phagocytic cells to engulf the membrane-bound fragments.

Where does lactic acid fermentation occur in the process of cellular respiration?
Lactic acid fermentation occurs in the absence of oxygen during the process of cellular respiration, specifically in the cytoplasm of cells.
What might happen if apoptosis did not occur in cells that have significant DNA damage?
If apoptosis did not occur in cells with significant DNA damage, these cells could potentially undergo uncontrolled division and give rise to cancerous tumors. Apoptosis is a natural process that helps prevent the proliferation of damaged cells, so its absence could lead to the survival of mutated cells that may pose a threat to the organism's health.
What During the process of cellular respiration energy is released from?
During cellular respiration, energy is released from the breakdown of glucose molecules. This process involves a series of biochemical reactions that occur in the mitochondria of cells, ultimately producing ATP, the cell's main energy source.
Where does cellular repiration occur in cells?
Cellular respiration occurs in mitochondria
What do cellular respiration and fermentation have in common?
Both occur after the process of glycolysis, or the process of "splitting sugars," in cellular respiration. So both can release chemical energy from sugars. Also, both processes end up producing adenosine triphosphate (ATP), a nucleotide considered to be the universal source of energy for metabolism among all living organisms.
What chemical changes occur during the digestive process?
Cellular respiration
How does the cellular process of omosis occur?
how does cellular respiration occur
A cell normally undergoes apoptosis when?
A cell normally undergoes apoptosis when it dies. It is the process of programmed cell death that might occur in multicellular organisms.
Where does lactic acid fermentation occur in the process of cellular respiration?
Lactic acid fermentation occurs in the absence of oxygen during the process of cellular respiration, specifically in the cytoplasm of cells.
Does continuous mass cell death occur for all types of animal cells?
Continuous mass cell death occurs for all types of animal cells. It refers to a cellular process called apoptosis, or programmed cell death.
What might happen if apoptosis did not occur in cells that have significant DNA damage?
If apoptosis did not occur in cells with significant DNA damage, these cells could potentially undergo uncontrolled division and give rise to cancerous tumors. Apoptosis is a natural process that helps prevent the proliferation of damaged cells, so its absence could lead to the survival of mutated cells that may pose a threat to the organism's health.
What During the process of cellular respiration energy is released from?
During cellular respiration, energy is released from the breakdown of glucose molecules. This process involves a series of biochemical reactions that occur in the mitochondria of cells, ultimately producing ATP, the cell's main energy source.
Why would glycolysis stop if neither fermentation or respiration functioned in the cell?
By there being no Oxygen during cellular respiration, then another process called Fermentation would occur which carries on with cellular respiration without oxygen molecules being present during the cycle, but the results of cellular respiration would still be the same.
What processes typically occur after the singal transduction pathway?
After the signal transduction pathway, the cell typically undergoes a cellular response, which can include gene expression changes, enzyme activation, or cytoskeletal rearrangements. This response leads to specific cellular outcomes such as cell growth, differentiation, or apoptosis.
What happens to cytoplasm during interphase?
During interphase, the cytoplasm serves as the medium in which various cellular processes occur, such as protein synthesis, organelle function, and cellular growth. It is a dynamic mixture of water, proteins, ions, and organelles that support cellular function and maintain homeostasis.
What does not occur in photosynthesis?
Cellular respiration does not occur in photosynthesis. Photosynthesis is a process where plants use sunlight to convert carbon dioxide and water into glucose and oxygen, while cellular respiration is the process where cells break down glucose to produce energy.
Type of compounds broken down during cellular respiration?
During cellular respiration, carbohydrates, fats, and proteins are broken down to produce energy in the form of adenosine triphosphate (ATP). This process involves a series of biochemical reactions that occur in the presence of oxygen.
