Name one nutritional disorder found in children caused by a deficiency of protein and energy in the diet?
marasmus could be one... another is kwashiorkor...
What happens in the photosystem II protein when it is hit by a photon of light?
When a photon of light hits the photosystem II protein, it excites an electron within the chlorophyll molecules in the protein. This electron is then passed along a series of molecules within the protein, resulting in the generation of a proton gradient and the release of oxygen as a byproduct of water splitting.
The actual transport of protons by the proton pump is mediated by a transmembrane protein which undergoes a change in its?
conformation during the transport process. This conformation change allows the protein to alternately bind and release protons on opposite sides of the membrane, resulting in the movement of protons across the membrane against their concentration gradient.
Why is X-ray radiation required in protein structure determination?
Protein structure determination is basically crystallography i.e. finding out the arrangements of atoms. This technique uses Diffraction maxima and minima to determine 3D structures. For diffraction to occur, the size of the obstacle must be close to the wavelength of light used. Since the obstacles in this case are molecules, we use X rays, whose wavelength is comparable to radius of molecules.
How many grams of nitrogen are contained in 2500 kcal diet that provides 15 percent of the energy as protein?
To calculate the amount of nitrogen in a diet, you typically assume that 16% of protein is nitrogen. In this case, if 15% of the energy in the diet comes from protein, you can calculate the total protein in the diet (2500 kcal * 0.15 = 375 kcal from protein). Then, convert this to grams of protein using the fact that protein provides 4 kcal/g. Finally, since protein is about 16% nitrogen, you can calculate the total grams of nitrogen in the diet.
Are there any different characteristics regarding Marasmus and Kwashiorkor?
Marasmus is a condition involving both severe protein deficiency and markedly inadequate intake of calories. Kwashiorkor is a condition involving severe protein deficiency, but in the context of sufficient or only mildly deficient intake of carbohydrates and calories, overall.
What does Marasmus develop from?
Inadequate energy and protein intake (or nutrient intake overall)
What causes the two types of protein-energy malnutrition?
Kwashiorkor occurs with fair or adequate calorie intake but inadequate protein intake, while marasmus occurs when the diet is inadequate in both calories and protein.
Marasmus usually is associated with a deficiency of?
Marasmus is caused by the deficiency of protein
What is a person suffering from marasmus?
A person suffering from marasmus experiences severe malnutrition, typically due to a significant deficiency in calories and protein. This condition often manifests in extreme weight loss, wasting of muscle and fat, and stunted growth, particularly in children. Symptoms may include dry skin, brittle hair, and a weakened immune system. Marasmus is often associated with poverty, inadequate food supply, and chronic illnesses.
Marasmus describes what form of malnutrition?
Marasmus describes a severe form of protein-energy malnutrition that results from inadequate intake of calories and nutrients over an extended period of time. It is characterized by extreme wasting and loss of muscle mass, often leading to severe physical and developmental impairments, particularly in children.
What is a protein energy malnutrition?
Protein-energy malnutrition (PEM) is a condition resulting from inadequate intake of protein and calories, leading to significant health issues. It primarily affects children and can manifest as kwashiorkor, characterized by edema and fatty liver, or marasmus, which involves severe wasting and stunted growth. PEM can result from poverty, food insecurity, or illnesses that impair nutrient absorption. It poses serious risks, including weakened immunity, developmental delays, and increased mortality rates.
What is the preventions of marasmus?
Marasmus is a medical condition found in children that is caused by malnutrition. A symptom is the wasting away of muscles. To prevent this, a child should eat nutritious foods that contain adequate amounts of protein and vitamins.
What is the term applied to a more severe condition that results from a deficiency of protein and calories?
The condition is known as "marasmus", which is a subset of malnutrition. Note that for clinical purposes, the above is often refered to as either "protein-calorie deficiency" or "protein-energy deficiency". All refer to the same condition.
What effects does marasmus have on the body system?
Marasmus is a severe form of malnutrition characterized by inadequate intake of calories and protein, leading to significant weight loss and muscle wasting. It primarily affects the body's ability to maintain essential physiological functions, resulting in weakness, stunted growth in children, and compromised immune response, making individuals more susceptible to infections. Additionally, marasmus can cause long-term developmental delays and impairments in cognitive function. Overall, it severely impacts energy levels, organ function, and overall health.
What is Athrepsia?
Athrepsia is extreme debility in children caused by malnutrition. Children are undernourished due to a deficiency in protein and calories. This condition is also called marasmus.
What is the difference between kwashiorkar and marasmus?
Marasmus is caused by a severe deficiency of nearly all nutrients, especially protein and calories. A child with marasmus looks emaciated and body weight may be reduced to less than 80% of the normal weight for that height. Marasmus occurrence increases prior to age 1 whereas kwashiorkor occurrence increases after 18 months. Kwashiorkor is a type of malnutrition with controversial causes, but it is commonly believed to be caused by insufficient protein intake. It usually affects children aged 1-4 years, although it also occurs in older children and adults.
