Process of breaking down glycogen Glycogenolysis Glycogen stored in liver used to provide ___ but glycogen stored in muscle used to provide ___ blood glucosefuel w/in that muscle FAs can be ___ for energy, or combined w/___ to form new TGs which are stored as fat oxidizedglycerol Catabolism of glycerol and FAs, which produces CO2 as waste product Lipolysis Diff b/w direct and indirect calorimetry Direct: amt of heat produced by metabolismIndirect: calculation of amt of heat produced by metabolism by using the direct relationship b/w O2 consumed and the heat produce by metabolism One MET equals ____ mL O2/kg/min 3.5 Diff b/w basal metabolic rate (BMR) and resting met rate (RMR) BMR: resting conditions, 12 hr fastRMR: resting conditions, 4-8 hr fast Metabolic rate influenced by: gender age physical activity body ___ body ___ body ___ ___ levels food intake genetics body surface area (BSA)body compositionbody temphormone Ratio of VCO2/VO2 Respiratory exchange ratio (R) R is around ___ during carb oxidation and __ during fat oxidation 1.7 What could skew R so it wouldn't tell us what is being used as fuel? Hyperventilation, which would increase CO2 levels and therefore skew the ratio Absolute oxygen consumption (VO2abs in L/min) = conditions for volume (3) [FIO2 x VI] - [FEO2 x VE] (VI=VE and must be corrected to STPD and in L/min)or=V(FIO2- FEO2)=V(.2093-FEO2) constant FIO2 = .2093 How to correct vol to STPD x .91 Relative O2 consumption (VO2rel in mL/kg/min) VO2abs x 1000 mL--------------------body weight (kg) A larger person will burn ___ kcal when doing weight-bearing exercise than a smaller person. A larger person will burn ___ kcal when doing non-weight bearing exercise than a smaller person. B/c __. moresame amtweight affects intensity of exercise Caloric expenditure (kcal/min) = VO2 x 5kcal/L Respiratory exchange ratio = VCO2abs-----------VO2abs Largest factor of BMR genetics thyroxine, epinephrine, growth hormone all ____ BMR increase Sleep ___ BMR decreases 4 types of tissue epithelialmuscleconnectivenervous Is epithelial tissue vascular or avascular? Innervated or not? Avascular; innervated Epithelial cells can be simple or stratified, which means: simple: 1 layerstratified: 2+ layers Cells which are adapted for diffusion or protection and have disc shaped nucleus Squamous ep cells Simple squamous ep cells are for ___ and are found in ____. Stratified squamous ep cells are for ___ and are found in ____. diffusion; capillaries, lungs, lymph vesselsprotection; esophagus, mouth, skin Skin has ___ ___ cells on upper layer but ___ and ___ cells on lower layer stratified squamous epcuboidal, columnar ep ___ cells are cube shaped, have rounded nucleus, and are active in transport; found in kidney tubules cuboidal ep cells ___ tall thin cells which are for secretion and absorption and have elongated nucleii; found in stomach and intestines columnar ep cells 2 types of muscle cells are smooth, cardiac, and skeletal. which are straited? cardiac, skeletal Long, cylindrical cells which are multinucleated skeletal muscle Mononucleated cells which have intercalated disks and are short and branched Cardiac muscle Spindle shaped cells which are mononucleated and have no striations smooth muscle _____ cells are diff from neurons and insulate and protect; also non-conducting Neuroglial Ability of a tissue to adapt to stressors Plasticity Endurance trainers increasing # of mitochondria in skeletal muscle tissue is an example of: plasticity flux = #mol/sec Authorbkheath ID120525 Card SetPhysLab Final Metab & Histology DescriptionMetabolism Phys Lab Final Updated2011-12-04T23:37:56Z Show Answers
