A young child has recently been diagnosed with Pompe disease, which causes severe muscle weakness and muscle tone. The patient l
acks the enzyme alpha-glucosidase (GAA). A lack of this enzyme leads to accumulation of the carbohydrate glycogen in muscle cells. Based on your knowledge of biological macromolecules, which argument best supports why this disease is occurring? Question 13 options: Glycogen is a protein and the enzyme, alpha-glucosidase, is not breaking it down into the lipid glucose. Glycogen is a protein and the enzyme, alpha-glucosidase, is not breaking it down into the nucleic acid glycerol . Glycogen is a polysaccharide and the enzyme, alpha-glucosidase, is not breaking it down into its monomer, fatty acids and glycerol. Glycogen is a polysaccharide and the enzyme, alpha-glucosidase, is not breaking it down into the monosaccharide glucose.
<em>Glycogen is a polysaccharide and the enzyme, alpha-glucosidase, is not breaking it down into the monosaccharide glucose.</em>
Explanation:
Pompe disease is an inheritable disorder that affects many parts of the body, especially the heart and other muscles.
People that are diagnosed with the disease present a defect in a gene called AAG. The enzyme alpha acid glucosidase is not present in the organism or it just does not work properly. These people have problems in processing the polysaccharide glycogen.
The AAG enzyme is located in the lysosomes, and its function is to decompose the polysaccharide glycogen (complex sugar) into the monosaccharide glucose (a simpler sugar). This last one is the source of energy of the organism.
The unproperly functioning of the enzyme causes the accumulation of glycogen in lysosomes of the macrophages.
During prophase I, the chromosomes condense and become visible inside the nucleus. Because each chromosome was duplicated during the S phase that occurred just before prophase I, each now consists of two sister chromatids joined at the centromere.

A keystone is a organism that helps define the entire ecosystem, and if the species were to disappear from the ecosystem no other species would be able to fill its ecological niche the ecosystem would be forced to radically change allowing new and possibly invasive species to populate the habitat.
Oxidation of NADH by electron transport chain ensures a continuous supply of NAD+ for glycolysis.
Explanation:
To continue the process of glycolysis, cells must have a continuous supply of NAD+ which is required during one of the reactions of the payoff phase of glycolysis. Two molecules of NADH are formed per glucose molecule during glycolysis. The NADH gives its electrons to the terminal electron acceptors (O2) via electron transport chain. This ensures that the process of glycolysis is continued in cells to breakdown the glucose into pyruvate.
True due to the hormones that act upon the kidneys Two examples being Antidiuretic Hormone (ADH) and Aldosterone ADH increases water permeability of the kidney tubules and Aldosterone decreases the Sodium in the urine and increases the Potassium.
