The presentation of an 18-month-old with hereditary fructose intolerance (HFI), deficiency of aldolase B and low blood glucose levels is due to accumulation of fructose-1 phosphate and the inhibition of glycolytic-gluconeogenic pathways.
Explanation:
Hereditary fructose intolerance leads to deficiency of fructose-1-phosphate aldolase enzyme. This enzyme deficiency leads to accumulation of fructose-1 phosphate in the liver. Fructose-1 phosphate inhibits the action of phosphorylase enzyme which monitors the glycogen to glucose conversion. Since glucose formation is reduced, hypoglycemia and lactic acidosis takes place accounting for the patient’s low blood sugar.
Answer:
<h2>Two normal cells, n and n;</h2><h2>One cell lacks chromosomes : n-n</h2><h2>One cell contain extra set of chromosomes: n+n=2n</h2>
Explanation:
If all of the chromosomes experience non-dis-junction in meiosis II, means that sister chromatids failed to separate during meiosis II then
a. half the cells are normal containing n number of chromosomes (n).
b. One cell lacks whole set of chromosomes
c. and one cell with two copies of the chromosomes (n+n).
The theory of Continental Dift
Answer:
Explanation:
When you are thirsty, it's your body's way of telling you to drink some water because you are dehydrated. Just like a dehydration reaction, you've lost water. Dehydration reactions are named as such because as the polymers are linked together, a molecule of water is released. This happens because on one end of a monomer is a hydrogen atom (-H) that is just waiting to bind with a hydroxyl group (-OH) on another monomer. Hydroysis which is the reverse of dehydration work the same way.
Phospholipids are amphipathic molecules. This means that they have a hydrophilic, polar phosphate head and two hydrophobic fatty acid tails. These components of the phospholipids cause them to orientate themselves, so the phosphate head can interact with water and the fatty acid tails can't, hence forming a bilayer.
Macromolecules are large structures composed of atoms and smaller molecular structures and play important and sometimes vital roles in creating and sustaining life. It can be organized into four categories: proteins, nucleic acids, carbohydrates, and lipids.
Carbohydrates:
Found in many energy-providing foods, carbohydrates help the nervous system, muscles, and body in general function. A group of polymers, they contain nothing but carbon, hydrogen, and oxygen. Human bodies break down carbohydrates into their base components, which it then uses to fuel cells and maintain body processes. Plants use carbohydrates, particularly cellulose, to protect their cells and to grow larger. The list of carbohydrates is extensive and includes all sugars and starches.
