Question

Which of the following cellular functions would be most directly related to a malfunction of the Golgi apparatus?
a)ATP production
b)degradation of macromolecules
c)secretion of proteins
d)cell movement

Is it b?

A patient exhibits a diverse range of symptoms. Lab tests reveal that multiple metabolic processes are occurring at sub-normal levels due to the lack of nutrients (e.g., glucose) and molecular building blocks (e.g., amino acids). Tests also reveal that cells are not secreting materials normally and have improper intracellular concentrations of ions, including potassium and sodium. These laboratory results can best be explained if which cellular structure is not functioning properly?
a)mitochondria
b)peroxisomes
c)lysosomes
d)plasma membrane
e)centrosomes
Is it a?

a)mitochondria
b)rough endoplasmic reticulum
c)peroxisomes
d)lysosomes
e)smooth endoplasmic reticulum

Is it e?
