milliliters (mL) of O2 consumed per minute (mL/min) Liters of O2 consumed per minute (L/min) mL of O_2 consigned per kg body mass per min (mL/kg/min) mL of O2 consumed per meter height per min (mL/m/min) Liters CO2produced per min divided by liters O2 convened per min Runners Joe end Tom base the tame VO2max, but Joe has a higher lactate anaerobic threshold. Which is the most likely outcome of a 10K race? Joe will finish ahead of Tom. Tom will finish ahead of Joe. They will cross the finish line together. Neither will finish because they are both wimps. Beta oxidation cuts the fatty acid chain into carbon segments of what length? 2 carbons 3 carbons 4 carbons 5 cartons If a person\'s R value is .95, are they burning more lipids or carbohydrates? (write L or C) Which of the following are true regarding lipids: They insulate the body The majority are stored as triglycerides in muscle tissue 1 gram provides 8 kcal of energy 1 gram pros ides 4 kcal of energy Ketone bodies are formed when: acyl CoA builds up insufficient carbohydrates are available lactic acid builds up a diet high in fats is eaten True or False. In the absence of oxygen, pyruvate will be concerted to lactate facilitated by the enzyme pyruvate dehydrogenase (PDH). Which statement best explains \"Lipids burn in a carbohydrate flame\"? Lipids are necessary to make oxaloacetate which is needed for the first step of the Krebs cycle Carbohydrates are necessary to make acetyl CoA Carbohydrates are necessary to make oxaloacetate for the Krebs cycle You can\'t cook a steak without charcoal True or False. The plateau in VO_2 observed during steady-state exercise suggests dial VO2max has been reached. Which of the following are true regarding locate threshold:

Solution

15.a
Since Joe has a higher lactate anaerobic threshold hence he will finish first as both have same VO2 max. The lactate anaerobic threshold is defined as the point where there is an step rise in the blood lactate levels during rigorous exercise.

16.a 2 Carbons

Beta-oxidation is a catebolic process by which fatty acids are broken down by oxidation of beta carbon atom to generate acetyl-CoA, which enters the citric acid cycle, and NADH and FADH2, which are co-enzymes used in the electron transport chain.

17. C .
A person having R value .95, are burning more carbohydrate. R is the respiratory quitent which is the ratio of metabolic gas exchange(R= Co2 produced/O2 uptake). Because the ratio of hydrogen to oxygen ratio in carbohydrate is same hence R=1.00 (.95 is close to 1); for lipid .60 < R <.73.

18. a,b,c are true regarding lipids.

d is false as 1 gram of carbohydrate releases 4 kcal of energy not lipid.
