Negative nitrogen balance often occurs when protein breakdown exceeds protein synthesis, such as during periods of starvation, illness, injury, or inadequate protein intake. This results in a net loss of nitrogen from the body, potentially leading to muscle wasting and other negative health consequences.

What people have an negative nitrogen balance?
Individuals with severe illness, injury, or malnutrition often have a negative nitrogen balance. This can also occur in people who are not consuming enough protein in their diet or are experiencing prolonged fasting or starvation. Athletes engaging in intense training without sufficient protein intake may also have a negative nitrogen balance.
What is the relationship of the amount of nitrogen retained in the body to the amount of nitrogen absorbed is called of protein?
The relationship between the amount of nitrogen retained in the body and the amount of nitrogen absorbed is known as protein balance. When the body retains more nitrogen than it absorbs, it is in positive protein balance, which is important for growth and repair. Conversely, negative protein balance occurs when the body loses more nitrogen than is absorbed, often seen in conditions like starvation or muscle wasting.
What is nitrogen condensation?
Nitrogen condensation refers to the process where gaseous nitrogen is cooled and converted into liquid nitrogen at a temperature of -196 degrees Celsius. This liquid form of nitrogen is often used in various industries for cryogenic applications, such as in medical, food, and semiconductor industries.
Did a scientist discover nitrogen?
Nitrogen was discovered by multiple scientists. Daniel Rutherford, a Scottish chemist, is often credited with the discovery of nitrogen in 1772 when he isolated the gas. However, the existence of nitrogen was known earlier, as it is a common element in the atmosphere.
How can one identify a polar molecule?
A polar molecule can be identified by looking at its molecular structure and determining if it has an uneven distribution of charge. This occurs when there is a separation of positive and negative charges within the molecule, creating a positive and negative end. This polarity is often caused by differences in electronegativity between the atoms in the molecule.

What can be often used to show a negative balance?
The color red shows a negative balance.
The relationship of the amount of nitrogen retained in the body to the amount of nitrogen absorbed is called the?
nitrogen balance. It refers to the state where the nitrogen intake, primarily from dietary protein, equals the nitrogen output, mainly via urine and feces. A positive nitrogen balance indicates that the body is retaining more nitrogen than it is excreting, which is often seen during growth or recovery from illness.
If you take in fewer calories than you need you have a energy balance.?
If you take in fewer calories than your body requires, you create a negative energy balance, not a neutral one. This deficit forces your body to utilize stored energy, often leading to weight loss. Maintaining a negative energy balance over time can result in significant changes in body composition. Conversely, a neutral energy balance occurs when calorie intake matches calorie expenditure.
Why do you get off balance?
You get off your balance most often due to inner ear problems. This usually occurs as a result of an infection or various diseases.
The electrical discharge in lightning often occurs between cloud and ground?
Yes, lightning typically occurs between a cloud and the ground, or between two clouds. It is caused by the separation of positive and negative charges within a cloud, resulting in a discharge of electricity to balance the charges.
Negative fluid balance?
Patients in the hospital often have their I and O (Intake and Output) monitored. If a person puts out more fluid than is taken in that person is said to have a negative fluid balance. If the person takes in more than he puts out then he is said to have a positive fluid balance.
Why does a COPD patient have a positive nitrogen balance?
COPD patients usually don't have a positive nitrogen balance, as the disease is more often associated with a general exhaustion of the body, and as such a net loss of total body protein. If a COPD patient does have a positive nitrogen balance, it simply means that the patient has eaten more protein than what has been broken down and excreted. This would most likely be associated with a positive net caloric intake and a gain of muscle weight.
What is the formula for N3 negative?
The formula for the azide ion, which is commonly represented as N₃⁻, consists of three nitrogen atoms bonded in a linear arrangement with an overall negative charge. The structure can be depicted as N=N=N, with the terminal nitrogen atoms carrying a formal negative charge. Azide is often used in various chemical applications, including as a propellant and in organic synthesis.
Why is nitrogen considered a limiting nutrient in ecosystems?
Nitrogen is considered a limiting nutrient in ecosystems because it is essential for plant growth and is often in short supply in the environment. This can restrict the growth of plants and other organisms, ultimately affecting the overall productivity and balance of the ecosystem.
What is the steps that removes nitrogen from the atmosphere?
Nitrogen is removed from the atmosphere primarily through the process of nitrogen fixation. This occurs when certain bacteria, often found in soil or root nodules of legumes, convert atmospheric nitrogen (N₂) into ammonia (NH₃), which can be utilized by plants. Additionally, lightning can also contribute by converting nitrogen gas into nitrates, which fall to the ground with rain. Finally, industrial processes, such as the Haber-Bosch method, also fix nitrogen for agricultural use.
