Which of these is a characteristic of body cells that require large amounts of energy?
They have a large number of mitochondria
They have a storage area for albumin proteins
They have a supplementary Y chromosome
They have a two-layer membrane
They have a large number of mitochondria is a characteristic of body cells that require large amounts of energy.
The characteristic of body cells that require large amounts of energy is that they have a large number of mitochondria.
The characteristic of body cells that require large amounts of energy is that they have a large number of mitochondria.
To arrive at this answer, let's break down the options and eliminate incorrect choices:
1. They have a large number of mitochondria: Mitochondria are known as the powerhouses of the cells because they are responsible for producing energy in the form of ATP through cellular respiration. Body cells that require a lot of energy, such as muscle cells, will have a higher number of mitochondria to fulfill their energy needs. Therefore, this is a characteristic of energy-demanding cells.
2. They have a storage area for albumin proteins: Albumin proteins are generally produced and stored in the liver. They act as carriers for various substances in the blood, but they are not directly related to energy requirements of cells. So, this option is unrelated to energy demand.
3. They have a supplementary Y chromosome: The presence of a supplementary Y chromosome is a genetic trait and not a characteristic of energy-demanding cells. It is unrelated to cellular energy needs, so this option is incorrect.
4. They have a two-layer membrane: All cells have a plasma membrane that consists of a phospholipid bilayer and regulates the movement of substances into and out of the cell. While some specialized cells like neurons may have additional layers, it is not directly associated with energy requirements. Therefore, this option is unrelated to energy demand.
In conclusion, the characteristic of body cells that require large amounts of energy is that they have a large number of mitochondria.
