The answer is true idk how to explain its just true sometimes but its super rare
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:
Non-green plants cannot make their own food because they do not have chlorophyll in their leaves which breaks down carbon dioxide and water molecules thus do not produce glucose(food).
The correct answer is option b. They receive instructions in their DNA.
The DNA (deoxyribonucleic acid) or the genes present in the cell guides the fate of the cells during the process of cellular differentiation in the embryonic life of the multicellular organism. The signaling molecule change the genetic expression changes, by which the cells are differentiated.
Answer: Option A.
Cause clot dissolution to proceed faster.
Explanation:
Plasminogen activator is a substance that activates plasminogen to plasmin. Plasminogen activator is a serine proteases which catalyze the activation of plasminogen. The damaged blood tissue releases tissue plasminogen. The plasmin is important to break fibrin polymers that is formed during clotting of the blood. Increased plasminogen levels cause blood clots to dissolve faster.
