Answer;
-Inhibitors
Chemical mechanisms that can turn off or reduce an enzyme are inhibitors.
Explanation;
-Enzyme inhibitors are molecules or compounds that bind to enzymes and result in a decrease in their activity. They can bind to an enzyme and stop a substrate from entering the enzyme's active site and/or prevent the enzyme from catalyzing a chemical reaction.
-Enzyme inhibitors are classified as either competitive or non-competitive inhibitors. Competitive inhibition occurs when the substrate and a substance resembling the substrate are both added to the enzyme.
-Non-competitive inhibitors are considered to be substances which when added to the enzyme alter the enzyme in a way that it cannot accept the substrate.
Answer:
Aldosterone.
Explanation:
Aldosterone is a hormone that regulates the levels of sodium and potassium in our body, which leads to regulate our fluid levels.
In order to increase the fluids in our system, aldosterone causes the absorption of sodium from our kidneys. The kidneys are the place where our body filters the blood absorbing what it needs, such as sodium, and excreting the rest as urine. With the entering of sodium to our bloodstream, water also enters, increasing the volume of blood in our body.
Aldosterone is also responsible for the excretion of potassium into the urine, controlling the levels of this ion, which is extremely important for a high number of reactions.
The mitochondria is known as the powerhouse of the cell. It is a membrane bound organelle and is found in the cells of most eukaryotes. The Mitochondria makes ATP and provides energy for the cell.
