NST 10 Midterm #2 UPDATED ACTUAL Questions and
CORRECT Answers
where is most of our energy in TG in adipose tissue (around 135,000 cal of fat in body)
stored?
the amount of nitrogen consumed (N in) as compared with the
nitrogen balance
amount of nitrogen excreted (N out) in a given period of time.
, Phase 1 : Glygogen depeletion - high rates of lean muscle and
nitrogen lost
Phase 2 : fatty acid oxidation - ketosis, reduced nitrogen and
3 stages of starvation
tissue losses (around 7 days)
Phase 3 : Brain keton adaptation, brain stops using glucose and
reduces need for glucogenesis
how long can people starve 60-90 days or more if hydration/electrolytes kept
(and how?)
a normal metabolic process that helps the body utilize stored fat
ketosis
when other sources of energy are lacking
The creation of glucose in the liver from non-carbohydrate
Gluconeogensesis sources, particularly glycerol, lactate or pyruvate, and alanine
(AMINO ACIDS)
what organs are involved in liver, pancrease, adipose, muscle, brain, kidney, endocrine
metabolic response to organs
starvation?
gylcogen depletion: less glucose released to blood, lower
what does the liver do when the
blood sugar, stops producing insulin and increased fatty acid
body is adapting to starvation?
oxidation/ketosis, reduced glucogenesis
fatty acid oxidation the metabolic breakdown of fatty acids to acetyl CoA
growth factors: shorter pop.
reproductive system: loss of period
thyroid axis: reduced utility (thyroid helps w energy expenditure,
consequences of starvation so you loose weight --> less energy!)
insulin sensitivity
less leptin secretion (leptin, made by fats, turns on estrogen, so
without this, no periods/puberty)
the state of being without reliable access to a sufficient quantity
Food insecurity
of affordable, nutritious food (in socially acceptable way)
Physical, social, and economic access at all times to safe and
nutritious food sufficient to meet dietary needs and food
Food secruity
preferences for an active and healthy life (and for all members of
household to have)
- slight difficulty accessing adequate food
marginal food security - quality, variety, and quantity of their food intake were not
substantially reduced
what states with the most food south and the midwest (mississippi, texas, arkansas)
insecurity
1. Availability
2. Access
4 pillars of food security
3. Utilization
4. Stability
An area characterized by a lack of affordable, fresh and
food desert
nutritious food.
