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 42 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.) kg The metabolism of 1 gram of fat generates approximately 8.89 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? %

A normal fasting blood sugar level is 0.0039 – 0.0055 mol / L. For a 3.0 x 10-4 mL sample of blood, calculate the maximum mass of glucose, C6H12O6, (in grams) that corresponds to a normal result.

I'm stuck on part  d, e, f, and g. Please help

Hello, these questions were not answered and I was wondering if I could get  some help answering them .

Soy sauce is prepared by fermenting a salted mixture of soybeans and wheat with severalmicroorganisms, including yeast, over a period of 8 to 12 months. The resulting sauce (aftersolids are removed) is rich in lactate and ethanol. How are these two compounds produced? Toprevent the soy sauce from having a strong vinegar taste (vinegar is dilute acetic acid), oxygenmust be kept out of the fermentation tank. Why?

- Part A When blood glucose levels rise following a meal, the events listed below occur. Arrange these events in the appropriate sequence. Arrange the events from earliest to latest. Reset Help Glycogen synthesis Glycolysis replenishes ATP supplies. (glycogenesis) occurs with excess Blood levels pass through normal to below normal Glucose is absorbed by cells. Glucagon is secreted. Insulin levels rise. glucose. (hypoglycemic). The liver releases glucose into the bloodstream. earliest latest

Kidney stones are crystals of calcium oxalate that form in the kidney, ureter, or bladder. Small kidney stones are passed out of the body easily, but larger kidney stones may block the ureter causing severe pain. If the [Ca2+] in blood plasma is 5 × 10-3 M, what [C2O42-] must be present to form a kidney stone? (Calcium oxalate Ksp = 2.3 x 10-9)

4. Isopropyl alcohol is commonly known as rubbing alcohol. Seventy percent rubbing alcohol is a disinfectant because it is believed to kill microorganisms by means of dehydration O denaturation of bacterial proteins disruption of bacterial protein synthesis O disruption of bacterial cell wall synthesis

In biological systems, a FACILITATED transport process is a form of _______  transport, where an important chemical component moves with the aid of a channel or similar structure.  According to the course lectures, Zoom sessions, course lecture notes, and/or assigned course readings, one specific example of a facilitated transport structure in the cell membrane is _________ , which aids in the movement of a particular chemical component called  __________. A PASSIVE transport (or diffusion) process is one in which an important chemical component moves from where it is  in concentration to where it is ________ in concentration. Meanwhile, an ACTIVE transport process is one in which an important chemical component is moved from where it is  in concentration, to where it is _________  in concentration.  Between passive and active transport, it is _________ transport that requires energy (of some form) to occur

The basal metabolic rate (BMR) of a person is the daily energy use for a person at rest to keep our essential processes running.  An equation for the BMR for a woman is shown below. BMR (kcal) = (4.54 × weight in lb) + (15.9 × height in inches) - (5 × age in years) - 161 Determine the basil metabolic rate of a 136 lb, 5' - 4" 20 year old woman in watts.  You will need to convert from kcal to joules.

Question 5 of 10 5. Fats have a high amount of stored energy because once ingested, they quickly and easily dissolve in the body making them readily accessible the hydrocarbon chains haye many bonds that take time to break down Fats are actually low in stored energy due to a lipid barrier that makes the breakdown of these molecules more difficult than other sources of energy ( Previous Next > FLODE7CTICC TTTLCracLIVE CL unlock your progress and your instructor will first be contacted for permission to do so.

Q5:

How does the principle of dialysis help clear toxic wastes from the human body?

The primary use of ingested proteins in the body is to _____.     be broken down into amino acids that are used to build proteins and nucleic acids within the body be broken down to release energy and the unused components are recycled to build new proteins within the body interact with signaling molecules to trigger the building of muscle fibers be converted to starches or sugars, which are more readily accessible forms of energy

As some people age their skin becomes lighter in color due to reduced activity of the pigment producing cells in the skin, melanocytes. True or False

True or False: Enzymes are proteins that slow chemical reactions down and therefore make food more stable.
