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.
Answer:
Starch molecules are too large to diffuse into cells.
Explanation:
As mentioned "Starch molecules are actually long chains of glucose molecules"
Thus they are broken down to glucose To make their transport (by diffusion) easier.
This is false! you may get flu like symptoms after the shot, but not the full fledge flu. this is because your body may have a different reaction to the shot.
Our muscular system works alongside with nerve impulses, the muscles and of course, the brain cells too. Muscle contractions happen when these three works all together. Nerve impulses are triggered by different stimuli and once the body senses, movement becomes possible as the brain sends the muscles the signal to move.
