Mitochondrion use and functions Cytoplasm (Cytosol) use and function
Cellular respiration occurs in the mitochondria.
The equation for cellular respiration is as follow:
C6H12O6 + 6O2 ---> 6 CO2 + 6 H2O + Energy (~38 ATP)
Thus, in the presence of oxygen, cellular respiration takes food (such as glucose, C6H12O6) and converts it into carbon dioxide, water, and energy in the form of ATP.
Because energy (ATP) is made in the mitochondria, it is commonly referred to as the "powerhouse" of the cell.
At one type, the cytoplasm was thought to be a passive part of the cell in which the organelles floated. However, scientists have learned that the cytoplasm plays many key roles within the cell.
Enzymes are housed in the cytoplasm that are needed for breaking down cellular waste and increase the speed of other chemical reactions within the cell.
The cytoplasm gives the cell its shape and helps support the cellular interior. If it were not for the cytoplasm, the cell would collapse on itself and the organelles would not be able to easily move throughout the cell.
An internal skeleton of sorts that is made of protein strands expands across the cytoplasm. This cytoskeleton helps to hold other structures with the cell in place while providing extra support.
