Q. 3
When a person dies, his or her body becomes stiff. Why does this happen?
Q. 4Although alcohol provides the body with a source of energy (7 kcal/g), many signs and symptoms of malnutrition are readily apparent in some alcoholics. Compare the metabolic effects of a lack of food (semi-starvation) to those caused by chronic, excessive alcohol intake. Would you anticipate the metabolic responses (in terms of energy metabolism) to be the same or different?Q. 5Do you know anyone who seems to have the same problems as Nicole? If so, would you feel comfortable talking about this with them?Q. 6When consumed in excess (as in Nicoles situation), alcohol can disrupt your bodys normal metabolic balance and lead to many serious health problems. Yet, the U.S. Dietary Guidelines for Americans acknowledges that moderate alcohol consumption (1 to 2 drinks/day) may be beneficial for some individuals. Although alcohol provides the body with a source of energy (7 kcal/g), it is not generally considered a nutrient. Furthermore, not all people are able to drink responsibly. As such, do you think the U.S. Dietary Guidelines for Americans should include recommendations regarding alcohol consumption?
Q. 7Many people assume that alcohol is harmful to the body only after many years of chronic and excessive intake. Yet, by the time she was in college, Nicole had already developed a condition called fatty liver, which results when certain types of lipids (triglycerides) accumulate in the liver. Alcohol metabolism depletes NAD+ availability in cells, causing NADH + H+ to accumulate. Review the metabolic pathways discussed so far and try to determine how a low NAD+ to NADH + H+ ratio can increase lipogenesis. Q. 8How do you differentiate between a problem drinker and an alcoholic?
