Question

A) In some instances, the levels of LDL cholesterol exceed the ability of the body to maintain homeostasis, and as a result, the excess material accumulates into fatty deposits that harden into plaques. Arrange in the correct order the sequence of events that leads to this condition, known as atherosclerosis:

1) The plaques harden, blocking the flow of blood in major arteries.
2) White blood cells become engorged with fatty deposits.
3) Excess LDL cholesterol accumulates in the interior of arterial walls.
4) Macrophages are drawn to this site.

B)

What happens to your blood pH if you go into ketosis? O increases O decreases O stays the same

C)

D)

Answer 1

The building up of plaque inside the walls of blood vessels is called atherosclerosis. It is an inflammatory condition which is initiated in the inner lining of the arteries. The sequence of events that leads to this condition is as follows » Excess LDL cholesterol accumulates in the interior of arterial walls Macrophages are drawn to this site White blood cells become engorged with fatty deposits The plaques harden, blocking the flow of blood in major arteries » Thus, the correct order is as follows: 3, 4, 2 and l B) Ketosis leads to the condition of metabolic acidosis. Ketone bodies are usually composed of organic acids. Accumulation of the ketone bodies in the body causes the ketosis and when the kidneys are unable to remove these ketone bodies, the pH of the blood falls automaticallv Thus, the correct option is decreases C) The fatty acids prevent the glucose of the body to get oxidized and itself oxidize to yield ketone bodies. These ketone bodies and fatty acids provide energy for the body and spare the glucose molecule for the brain use. The types of ketone bodies are acetone, acetoacetic acid and beta-hydroxybutyric acid. These three are considered as biological ketone bodies and remaining ones are nonbiological ketone bodies Thus, Biological ketone bodies Nonbiological ketones acetone ethyl methyl ketone
