When fat is used as energy what is excreted in the urine?
ketones
Why is fat-soluble vitamins not excreted in urine?
Vitamins which are water soluble only will be excreated by urine--ex-b-complex
Which vitamins are excreted in urine?
Vitamins that are water-soluble, such as vitamin C and the B vitamins (e.g. B1, B2, B6, B12), are excreted in urine if they are consumed in excess and not needed by the body. Fat-soluble vitamins (A, D, E, K) are stored in the body's fat tissues and liver, so they are less likely to be excreted in urine.
If someone consumes excess energy from protein the extra protein is used for?
The extra amount of protein can either be metabolized, stored as triacylglycerol in the fat stores or excreted by the urine (most likely to happen if your eat more than 3.0 g/day/body weight).
What happens to excess amino acids in the body and how does the body process them?
Excess amino acids in the body are typically converted into energy or stored as fat. The body processes them by breaking them down through a process called deamination, where the amino group is removed and converted into ammonia, which is then converted into urea and excreted through the urine. The remaining carbon skeleton of the amino acid can be used for energy or stored as fat.
Why are fatty acids not excreted in urine?
Fatty acids are converted into acetyl-CoA through beta-oxidation in the liver before being further metabolized to produce energy. Since they are broken down and utilized for energy production, fatty acids are not typically excreted in urine. Instead, any excess fatty acids are stored as triglycerides in adipose tissue for later use.
How is fat excreted from the body?
Fat is primarily excreted from the body through a process called lipolysis, where fat molecules are broken down into fatty acids and glycerol. These byproducts are then released into the bloodstream and transported to tissues where they are metabolized for energy or stored. Excess fat can also be eliminated through the lungs as carbon dioxide or excreted in feces.
45.If you have a friend who lost 7 kg (about 15 pounds) of fat on a regimen of strict diet and exercise. How did the fat leave her body?
When your friend lost 7 kg of fat, the fat was converted into energy through metabolic processes. During this process, the body breaks down stored fat into fatty acids and glycerol, which are then used for energy or converted to carbon dioxide and water. The carbon dioxide is exhaled through the lungs, while water is excreted through urine, sweat, and other bodily fluids. Essentially, fat loss results in the release of energy and byproducts that exit the body.
Why can your body store a fat-soluble vitamins but not water soluble vitamins?
Fat-soluble vitamins are stored in the body's fat tissues, while water-soluble vitamins are excreted in urine when in excess since the body does not store them. This is because fat-soluble vitamins can be stored in fat cells and released when needed, while water-soluble vitamins are readily excreted when the body has enough.
What happens to excess fat in the body?
When the diet provides the body with more calories than it needs for general maintenance and its current level of physical activity, this excess energy is stored in the form of body fat. Fat acts as a food reserve and as padding and protection. The fat in the abdomen helps to protect the organs under it.
How do fat soluble vitamins differ from water soluble vitamins?
Fat-soluble vitamins are stored in the body's fat tissues and can be stored for longer periods of time, while water-soluble vitamins are not stored in the body and are excreted in urine if consumed in excess.
What happens to body fat when you lose weight and how does the body process it?
When you lose weight, your body breaks down fat stores for energy. This process is called lipolysis. The fat molecules are released into the bloodstream and transported to the liver, where they are converted into energy or excreted from the body.
