Answer:
The correct option is C.
Explanation:
From the information given in the question, it is obvious that De-Shawn created two models of the heart in order to show the differences that exist between the heart of a smoker and that of a non smoker. Smoking is an addictive habit that has great negative effects not only on the circulatory system of smokers alone but also on the whole body system.
Smoking normally damages the functions of the circulatory system by destroying the lining of the arteries; this leads to accumulation of fatty deposits that narrow the width of the arteries. The narrow arteries will hinder blood from flowing normally and this can lead to different types of medical conditions such as stroke, heart attack, heart failure, coronary heart diseases, etc.
Pepsin enzymes can then digest dietary proteins in the lumen of the stomach. Pepsin in a protease digesting the proteins into smaller peptides. It is produced by the chief cells of the stomach in the form of a proenzyme called pepsinogen. A proenzyme or a zymogen is basically inactive and needs a biochemical change to become an active enzyme. This biochemical change is brought about by the acidic environment of the stomach by the secretion of the hydrochloric acid by the parietal cells in the stomach lining.
Answer:
a .Bromelain extract is a blend of protein-processing (proteolytic) chemicals and a few different substances in littler amounts. The proteolytic catalysts are sulfhydryl proteases; a free sulfhydryl gathering of a cysteine amino corrosive side chain is required for work. the monomer of this enzyme is aminoacid.
b.Bromelain isolates the amino acids in the compounds that cause browning by breaking the peptide bonds.
They Increase the surface area available for the absorption of nutrients
Answer:
Carbon binds to oxygen, hydrogen, and nitrogen covalently to form the many molecules important for cellular function. Carbon has four electrons in its outermost shell and can form four bonds. Carbon and hydrogen can form hydrocarbon chains or rings
