Enzymes are proteins that contains ribonucleic acid (RNA) .An enzyme binds to one or more reactant Molecule in order to catalyze a reaction.
Explanation:
1. Enzymes speed up chemical reactions by lowering the Activation Energy, which allows the reaction to proceed much more quickly.
2. During an enzymatic reaction, a molecule of Substrate binds to the enzyme and is broken down into one or more molecules of product, which are released.
3. The induced fit between an active site and its substrate often strains bonds and helps the reaction proceed
4. The specific location within an enzyme molecule where the substrate binds is called the Active site.
5. Lactose takes years to break down on its own. But if exposed to the protein lactase, the reaction proceeds very quickly, while lactase itself remains unchanged. Lactase is an example of an enzyme
6. High temperatures or changes in pH can an enzyme, causing it to lose its shape and biological activity. An inhibitor is a molecule that can bind to an enzyme and prevent the enzyme from working.
7. An enzyme is considered a Catalyst because it speeds up a chemical reaction without being used up.
Answer:
a. Heart
b. pulmonary artery
c. lungs
d. pulmonary vein
e. heart
f. aorta
g. arteries
h. big toe.
Explanation:
First I ( drop of blood) will go from the heart to the lungs through pulmonary artery in order to purification from carbondioxide and loaded oxygen. After that, I return to the heart through pulmonary vein and the heart pump this blood to the aorta which is a big blood vessel that branched into small arteries that reaches to every cell of the body and through these arteries I reach the big toe of the foot.

<span>A binge means eating to more than full in a short matter of time. Binge eating disorder is a life-threatening, but treatable eating disorder characterized by binges or eating large quantities of food in a quick manner to the point of discomfort.
