9/5 kin 110 class notes- Getting to know Jeno Graduate student, 3rd year doctoral studento Was previously a TA for the class for 3-4 yearso She studies glycemic control Significant for people with Type I diabeteso Loves cookingo loves music Goo goo dollso Outdoorsy persono Went to Australia last semester for a few monthso Camped in Utah last summero Lives in Greenfield- A tip for success in this class:o Don’t get bogged down in the detailso What’s the key point?o How to take notes? Writing down every word on the slide Paying attention to what I’m saying and writing down key points- You are what you eat…?o Yes or no poll- Basics of energy metabolismo Metabolism = sum of all life processeso Catabolism = break down of polymers (energy production)o anabolism = building up of polymers (energy storage)- movement of energy between systems and conversion energy to different forms of energy is the basis for life- 1st law of thermodynamicso energy can not be created or destroyedo But; it can be changed!o ex. plants transfer the energy from the sun (thermonuclear energy) into chemical bond energy in order to grow- suno what is it made of? Hydrogen and helium- Plantso What are they made of? Water Carbohydrates (CHO) Fiber- Animals (eat plants)o What are they made of? Protein Fat Water Little CHO- Humans have similar composition to a cowo Protein, fat, water…o Not much CHO- Are approximately what you eat if you are eating a balanced dieto NOT what you eat if you are a vegetariano Big point: energy we need for survival, physical activity, etc. comes from stored energy - Measure chemical bond energy?o Energy in food calorieso Bomb calorimeter Small bucket inside a big bucket of water Burn the food in the small bucket Measure the temperature change of the water, this can tell us how many calories it containedo 1 kcal (1 Calorie) = heat needed to raise 1 g of water by 1 degree Celsius- Energy measured in kcals (or Calories)o Calories vs. calorieso Nutrition labels use Calories/kcals- The ice dieto 1 gram ice = 120-160 calories (not Calories)o 1000 grams of ice = 120 kcalso 1 kg = 2.2 lbs of iceo would need to eat 60 lbs of ice to have a 1 lb difference on the scaleo link to this article on moodle website- Useful factso Molecules that have chemical bond energy (Calories) are CHO, PRO, FAT, alcoholo Water, vitamins, minerals, pencil eraser and fiber contain no usable energyo People contain a range of calories (400,000- 500,000 kcals) Depends on fat- Average person produces 1 kcal per minuteo Equivalent to lightbulb- Energy balanceo Relationship between energy intake (food) and energy expenditure (energy out)o *expend energy as ATP and heat- energy in = energy outo bird vs. Hela monster lizardo bird expends lots of energy so it needs to consume a lot of energyo the lizard barely expends any energy - it conserves energy all day just laying aroundo which is better? To eat a lot and expend a lot? Or eat hardly anything and expend very little energy? It depends on the goal- What do we mean by human performance?o Athletic Strength Speed Endurance Flexibility Staminao Goal: best possible performance- Health (wellness?)o Health: Homeostasis/balance Movement- Ability to do different things- Limitationso Arthritiso Multiple sclerosiso Human performance in that context? Maximize quantity of years alive? Minimize risk of disease Maintain ideal BMI, body image Highest quality of years aliveo Different for everyone, changes over
