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.

What might happen if apoptosis did not occur in cells that have significant DNA damage?
Most likely cancer would arise if apoptosis did not occur in cells that have significant DNA damage.
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.
Where does Cellular Respiration Occur.?
cellular respiration occurs in the mitochondria
Which of the following is a product of cellular respiration and not fermentation?
Aerobic cellular respiration requires oxygen. Therefore which ever process that requires Oxygen to make it occur is NOT a stage of aerobic cellular respiration.
Where does cellular repiration occur in cells?
Cellular respiration occurs in mitochondria
What chemical changes occur during the digestive process?
Cellular respiration
How does the cellular process of omosis occur?
how does cellular respiration occur
If there is no oxygen during the cellular respiration process the Krebs cycle does not occur?
False
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.
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 phase of the cell cycle and cellular process occurs during that phase?
The phase of the cell cycle is 3, and the processes of bivfalvism, deuteronomy and capsicum occur during it.
What might happen if apoptosis did not occur in cells that have significant DNA damage?
Most likely cancer would arise if apoptosis did not occur in cells that have significant DNA damage.
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 happens if oxygen is absent during the 2nd stage of cellular respiration?
fermentation will occur.
What process can occur during metamorphism?
everything
Does a plant use carbon dioxide in reactions during environmental light?
Yes; at the most basic cellular level, the reactions photosynthesis and cellular respiration both occur during times of light; the former utilizing the sun's energy and the latter as part of the metabolic process of organisms that convert nutrients to ATP.
What cellular metabolic processes occurs in all living things?
There cellular metabolic processes that occur in all living things refers to all chemical reactions in the cells. Cellular respiration is one such process.
