The organ near the stomach that produces, stores , and eliminates blood cells is the spleen.
<span>The role of the pollen is for the sperm to reach the egg. In the process of transportation, a lot of pollen grains can get lost and therefore there is greater need for it to be more than the ovules, since the eggs do not have to be transported anywhere. </span>
Enzymes are typically composed of amino acids.
Enzymes specifically binds to their substrate, and accelerate the biological or in-vitro reactions.
Four real-life examples of enzymes are: Lipase, Maltase, DNA ploymerase and Alcohol dehydrogenase.
Explanation:
All enzymes are proteins. They are composed of amino acids as monomer units linked by polypeptide bonds.
The substrate is a molecule which has specific enzyme binding sites for the highly specific enzyme called as active sites. With this binding, the enzyme-substrate complex is formed, undergoes the chemical reaction and new product is formed. Enzymes accelerate the biological reactions by lowering the reaction's activation energy.
Four-real life examples of enzymes are:
Lipase enzyme: catalyses the hydrolysis of fats and triglycerides in the small intestine. Lipase enzyme is secreted by pancreas.
Maltase enzyme: catalyses the breakdown of maltose sugar. It is secreted by salivary glands and our mouths.
DNA Polymerase Enzyme: It catalyses the DNA replication in the cells. It is secreted by the nucleus
Alcohol dehydrogenase: It catalyses many reactions in the body as the reduction of NAD to NADH. It is secreted by the liver.
