What helps supply energy for the cell?
Adenosine 5′-triphosphate, or ATP, is the most abundant energy carrier molecule in cells. This molecule is made of a nitrogen base (adenine), a ribose sugar, and three phosphate groups. The word adenosine refers to the adenine plus the ribose sugar.
What provides energy for the nucleus?
Nuclear energy is the energy in the nucleus, or core, of an atom. A nuclear reactor, or power plant, is a series of machines that can control nuclear fission to produce electricity. The fuel that nuclear reactors use to produce nuclear fission is pellets of the element uranium.
What is the nucleus covered by?
Like most other cellular organelles, the nucleus is surrounded by a membrane called the nuclear envelope. This membranous covering consists of two adjacent lipid bilayers with a thin fluid space in between them.
Which is the most important function of the nucleus?
It is the command center of a eukaryotic cell and is usually the most notable cell organelle in both size and function. The key function of the nucleus is to control cell growth and multiplication.
Which is a new energy source within the cells?
A new energy source within the cells. All our cells require the small molecule, ATP, generated in the mitochondria to cover the energy required for cell metabolism, dynamics and growth. To a lower extent and particularly in cancer cells, ATP can also be generated in the cytoplasm from the energy gained during degradation of glucose.
How does the nucleus send commands to the cell?
The nucleus sends “commands” to the cell via molecular messengers that translate the information from DNA. Each cell in your body (with the exception of germ cells) contains the complete set of your DNA. When a cell divides, the DNA must be duplicated so that the each new cell receives a full complement of DNA.
How does the nucleus regulate the production of proteins?
The nucleus regulates the synthesis of proteins in the cytoplasm through the use of messenger RNA (mRNA). Messenger RNA is a transcribed DNA segment that serves as a template for protein production.
