Which of the following best describes the connection between cardiovascular disease and age?
O A. As people age, their blood vessels become more elastic leading to less cardiovascular disease.
O B. As people age, the heart becomes more efficient with each pump, increasing cardiac output
O C. As people age, blood pressure decreases leading to more cardiovascular disease.
O D. As people age, plaque builds up in the arteries increasing vessel resistance, which leads to disease.
- D. As people age, plaque builds up in the arteries increasing vessel resistance, which leads to disease.
Plaque development can restrict these arteries, reducing blood flow to the heart. Reduced blood flow may eventually result in chest pain and shortness of breath A heart attack might be caused by a total blockage.

Answer:
<u>C</u>. containing
- <u><em>egg albumen </em></u>
- <u><em>protease </em></u>
- <u><em>dilute hydrochloric acid</em></u>
Explanation:
A protease is a kind of peptidase enzyme that breaks down proteins into peptide molecules. As a digestive enzyme it is located in the lining of the stomach where, relative to the hydrochloric acid in digestive juices, the pH is usually low/ acidic.
<em>Enzymes speed up reaction rates by </em><em>providing alternative pathways</em>. By modifying the enzyme composition, supplying more collision energy, and changing the collisions between and the ratio of reactants, certain variables will increase the reaction rate.
Proteases function well at 37℃, the typical internal temperature of the human body- this temperature provides adequate energy for the reaction. Similarly, proteases require low pH for the correct configuration, and beyond this pH and temperature, they may become denatured or simply not function well as catalysts.
