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.
<span>D. transmits impulses to the central nervous system from sense organs</span>
sensory neuron
Sensory neurons are the neurons responsible for receiving the information from the environment or the stimuli. This sensory neurons pass the message thru interneurons and then to Central Nervous System (brain and spinal cord) which then sends the signal to the motor neuron.
The term mosaic is used in arts for an art piece that is composed of many small pieces of materials like stones or glasses. However, in biology it is used for a structure that is made up of different types of cells.
Now if we have to describe a biological mosaic structure , then there is no perfect option than the structure of a cell membrane of animals' cells. Cell membrane is not made up of two types of cell at all but it is a structure that is composed of a lipid bilayer in which proteins are floating as you can see in picture.
The structure was explained as mosaic by fluid mosaic model. If we take a deep look, the double layer of lipids are made up of phospho lipids, which contain two fatty acid tails and a lipid head. The heads are hydrophilic and are outside while tails are hydrophobic and they are inside. This structure has alot of importance as per the function of cell membrane because it maintains the cell's internal environment and separates it from outer environment. This is because
As cell is surrounded by an environment which contain water in excessive amount, therefore nature has made cell membrane in a way that hydrophobic tails do not face water and stay inside the double membrance while hydrophillic heads face the water region outside the cell as well as inside the cell (cytoplasm that contains alot of water content too).
Hope it helps!
I think the Atrial fibrillation is the uncoordinated beating of the atria rapid. These are rhythm in which all the atrial activity is depicted as chaotic undulations of the base line. Atrial rhythms include; atrial fibrillation, atrial flutter, premature atrial contraction, wandering pacemaker. Atrial fibrillation can cause an increased risk of stroke, heart failure and other heart related complications.
In another fossilization process, called replacement, the minerals in groundwater replace the minerals that make up the bodily remains after the water completely dissolves the original hard parts of the organism<span>. Fossils also form from molds and casts.
