KPER 3470 Midterm 1
Where and how much can glucose be stored - ✔✔Muscle, as glycogen - 1600kcal
or in liver, 400 kcal
how many atp does etc produce - ✔✔32 atp
Where do lipids store glycerol - ✔✔in adipose tissue
Pyruvate - ✔✔3 carbon, end product of glycolysis, if there is enough O2 it goes to
mitochondria, if not it becomes lactate
VO2 and what it depends on - ✔✔rate of o2 consumption
- energy demands, 02 delivery to mito, ability of mito to convert atp
SV - ✔✔amount of blood ejected by heart per min
FICK - ✔✔rate of consumption/production - flow times difference
2 ways to measure vo2 - ✔✔1. blood- co2 x difference of o2 content vs artieral and
venous blood
2. respired air - min ventilation x dif in o2 content w/ inspired and expired air
what determines how efficent atp delivery is - ✔✔enzyme acitvity and # of mito
what does vo2 depend on - ✔✔o2 delivery and o2 metablosim (effect of training)
Hematocrit - ✔✔% of blood with rbc, 40%
EXAM - how are the e in etc removed - ✔✔by oxygen atoms
how many connections does H,O,N,C - ✔✔1,2,3,4
TG - ✔✔one glycerol and 3 fa, fa are always same 3, always even amount of carbon
what kind of reaction is phosphorlylation - ✔✔anaerobic alactic, one chemical reaction
what are the 4 roles of carbs - ✔✔energy, protein spacer, metabolic primer, cns fuel
recommended carb intake - ✔✔40-50% of cal, up to 70% if active
6-10 g per kg
what does intense and light exercise rely on - ✔✔intense: carbs
light; fat
Glycogenolysis, and what is this stimulated by - ✔✔breakdown of glycogen to glucose,
stimulated by increase in glucagon, epinephrine and norepinephrine, decrease in insulin
Recommended Lipid Intake - ✔✔No more than 30% of daily calories
Roles of lipids - ✔✔Energy source, hunger depressor, insulation, protection, vitamin
carrier
Lipoproteins - ✔✔chylomicrons, VLDL, LDL, HDL
- exogenous transport from intestines to liver
recommended protein intake - ✔✔.83g/kg of body , 1.2-1.8 when intensely active
3 sources of body protien - ✔✔blood plasma, muscle, viscera tissue
protein metabolism - ✔✔aa undergos deamination, nitrogen is removed to form UREA,
whats left can be converted to a different aa, carb,fat, energy
7 steps in glycemic index primer - important - ✔✔eat food
digest
increase in blood glucose
insulin is now secreted into blood
insulin facilitates glucose uptake from blood to cells
decrease in blood glucose
decrease in insulin secretion
*have a pic*
3 things to optimal diet - ✔✔balance, variety, moderation
men and lady cals - ✔✔men- 3000
women - 2000
What should lipid intake be based on - ✔✔1. personal taste
2. $
3. geographic
4. avability of lipid rich foods
Pre comp meal - ✔✔high carb, low others, 1-4 hours prior, 150-300g of carbs
during exercise eat what - ✔✔60 g hourly
post comp meal - ✔✔carb rich, HIGH GLYCEMIC FOODS TO SPEED UP GLYCOGEN
REPLENISHMENT, slow is usually better for health bc of insulin, do not want to
overwork pancreas
high med and low gi foods
why is high bad - ✔✔high - rice, g
