Yes
No, it is an example of positive nitrogen balance. This is because a pregnant women is in need of protein to allow growth of the child, and in order to build protein you need Nitrogen. Therefor pregnancy is considered positive nitrogen balance.
No, a growing child is not likely to exhibit negative nitrogen balance because they require more protein to support their growth and development. Negative nitrogen balance occurs when protein breakdown exceeds protein synthesis, leading to loss of muscle mass and other tissues. Children typically have a positive nitrogen balance due to their high protein needs for growth.
Nitrogen balance is not important in the process of building muscle, but testing for nitrogen can help determine whether protein consumption is optimal.
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.
Yes, a growing child is not likely to exhibit negative nitrogen balance because they require adequate protein intake for growth and development. Negative nitrogen balance typically occurs when the body is breaking down more protein than it is taking in.
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.
Positive nitrogen balance occurs when the total nitrogen excreted in the urine, feces and sweat is less than the total nitrogen ingested. Positive nitrogen balance must exist for new tissue to be synthesized. When dietary protein intake or total energy intake is inadequate to maintain tissues total nitrogen balance, negative nitrogen balance occurs and new tissue is unable to be synthesized.
Negative nitrogen balance
Nitrogen Balance = Nitrogen intake - Nitrogen loss Nitrogen intake = Protein intake (g/day) / 6.25 Urinary Urea Nitrogen (UUN) determined with 24hr urine collection Nitrogen loss = UUN (g/day) + 4g (to account for random nitrogen loss)
Nitrogen balance is the term that describes the comparison between nitrogen consumption and nitrogen excretion in a given time period. This balance is important to assess protein intake and utilization in the body.
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.
