The brain and spinal cord are both structures of the central nervous system.
The best answer is by breaking off a phosphate group from its structure.
ATP adenosine tri phosphate. It has three phosphate group attached to adenosine, hence the prefix "tri" for three.
During metabolism, a phosphate group is removed from ATP and energy is released for use by the cell. When this happens, ATP becomes ADP or adenosine di phosphate, "di" meaning two, i.e. adenosine remains with two phosphate groups. ADP is the core component of ATP.
A phosphate group is added again to ADP to make it ATP which is the form in which energy in the cell is temporarily stored before the whole process is repeated again
A cell wall is your correct answer
Answer:
X is negative heterotropic modulator
Explanation:
In allosteric regulations, modulators are molecules that causes a change in the conformation of an enzyme, hence, resulting a change in enzyme activity. It can lead to a decrease or an increase of the enzyme. When a molecule decreases the enzyme activity it called a negative modulator, when it increases or activates the enzyme activity, it is called a positive modulator.
A positive or negative modulator can either be homotrophic (substrate acts as modulator) or heterotropic (another ligand acts as modulator).
In the example above, X is negative heterotropic modulator, because the modulator is different from the substrate and it also decreases the enzyme activity.
His answer took years to develop. The theory of evolution says that all living things on Earth, including plants, animals and microbes, come from a common ancestor by slowly changing throughout the generations. Darwin suggested that the way living things changed over time is through natural selection
