15 Questions
What type of disorder is characterized by the inadequate metabolic rate to remove a normal substance such as fatty change in the liver?
Abnormal metabolism
Which type of disorders result from mutations causing defective folding and transport, leading to the accumulation of proteins like α1-antitrypsin deficiency?
Alterations in protein folding and transport
What term is used for disorders that result from inherited defects in enzymes, leading to the failure to degrade metabolites?
Storage diseases
In which type of disorder does an abnormal exogenous substance accumulate because the cell lacks the enzymatic machinery to degrade it or transport it elsewhere?
Inability to degrade phagocytosed particles
What is the term used for accumulations of abnormal exogenous substances like carbon or silica particles due to the lack of enzymatic machinery or transport capability within cells?
Alterations in protein folding and transport
What is the main reason for abnormal metabolism leading to fatty change in the liver?
Inadequate metabolic rate to remove a normal substance
Which type of disorder results from an accumulation of proteins due to genetic or acquired defects in folding, packaging, or transport?
Abnormal metabolism
What is the outcome of an inherited defect in an enzyme that prevents the degradation of a metabolite?
Storage diseases
Why do abnormal exogenous substances accumulate in cells when they lack the ability to degrade or transport them?
Insufficient enzymatic machinery or transport capability
Which factor is primarily responsible for the accumulation of carbon or silica particles within cells?
Lack of enzymatic machinery to degrade particles
What could lead to the accumulation of a normal or abnormal endogenous substance due to genetic or acquired defects in folding, packaging, transport, or secretion?
Deficiency of critical enzymes
Which condition results from the cell's lack of enzymatic machinery to degrade an abnormal exogenous substance or transport it to other sites?
Inability to degrade phagocytosed particles
What is a characteristic feature of disorders resulting from an inherited defect in an enzyme that causes the failure to degrade a metabolite?
Abnormal accumulation of substances
Which situation leads to the inadequate removal of a normal substance produced at a normal or increased rate?
Inability to degrade phagocytosed particles
What may cause the accumulation of proteins like α1-antitrypsin due to mutations affecting their folding and transport?
Defective protein degradation pathways
Test your knowledge of abnormal metabolism and alterations in protein folding and transport. Learn about conditions where substances accumulate due to genetic or acquired defects in folding, packaging, transport, or secretion.
