Chapter 25, Problem 7CT
Summary Introduction
To determine:
The reason that the loss of calories after sweat evaporation helps in weight loss.
Introduction
Sweating is the natural method of regulating body temperature. Sweating helps in releasing water and salt, this evaporates to cool the body.

He reasons that a liter (about a quart) of water weighs 1000 g, whichis equivalent to 580,000 cal, or 580 kcal, of heat when lost as sweat.Therefore, instead of reducing his diet by 580 kcal/day, he believesthat losing a liter of sweat every day in the sauna will cause him tolose about a pound of fat a week. Will this approach work? Explain.
When you jog, most of the food energy you burn above your basal metabolic rate (BMR) ends up as internal energy that would raise your body temperature if it were not eliminated. The evaporation of perspiration is the primary mechanism for eliminating this energy. Determine the amount of water you lose to evaporation when running for 32 minutes at a rate that uses 400 kcal/h above your BMR. (That amount is often considered to be the "maximum fat-burning" energy output. The latent heat of vaporization of water at room temperature is 2.5 106 J/kg.)The metabolism of 1 gram of fat generates approximately 8.65 kcal of energy and produces approximately 1 gram of water. (The hydrogen atoms in the fat molecule are transferred to oxygen to form water.) What fraction of your need for water will be provided by fat metabolism?
The uncoupling of photon movements results in thermoregulation. Explain and define the terms Brown fat and non shivering thermogenesis as to the production of heat in babies.

- The following questions apply to this information:A man licks a newt after being dared to do so by his boyfriend. Almost immediately, the man noticed that his lips and tongue felt numb. Within a few minutes, the man began to show a lack of coordination and skeletal muscle control. Within several more minutes, the man experienced difficulty breathing and symptoms of cardiac arrest. Eventually, the man dies. The newt's skin has tetrodotoxin in it. Tetrodotoxin is produced by rough-skinned newts as a form of defense against predation. Tetrodotoxin specifically blocks the sodium pore in voltage-gated sodium channels. It does not affect the gates of a voltage-gated sodium channel. The toxin has no other effects.We will use one bipolar neuron to answer the following questions. This neuron has a resting membrane potential of -65mV. 1) true/false While under the effect of tetrodotoxin, the man's neurons would be able to reach threshold potential at their initial segments. 2) true/false The…arrow_forwardAt Kate's next appointment, Paula showed Kate how to use a glucose meter. She instructed Kate to measure her blood glucose level twice a day before and after breakfast and dinner. Paula explains to Kate that her pre-meal blood glucose level should be 110 mg/dLmg/dL or less, and if it increases by more than 50 mg/dLmg/dL, she needs to lower the amount of carbohydrates she consumes. Kate and Paula proceed to plan several meals. Because a meal should contain about 45 to 60 gg of carbohydrates, they combined fruits and vegetables that have high and low levels of carbohydrates in the same meal to stay within the recommended range. Kate and Paula also discuss the fact that complex carbohydrates in the body take longer to break down into glucose and, therefore, raise the blood sugar level more gradually. Kate increased her exercise to walking 30 minutes twice a day. She began to change her diet by eating 6 small meals a day consisting of more fruits and vegetables without starch such as green…arrow_forwardAn animal living in a cold environment loses heat at a rate that is proportional to its surface area, but its metabolism generates heat in all of its cells, so the rate of heat generation is proportional to its volume.

If you take a baby outdoors on a cold day, you should dress it less warmly than you would dress yourself because it is smaller.
