Can someone please check my answers for the following 'choose the best answer'?

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?

Lab results show that a patient is suffering from an intracellular disorder directly interfering with several cellular functions. Affected cells exhibit low levels of lipids and high levels of intracellular toxins. These laboratory results can best be explained if which cellular organelle is not functioning properly?
a)mitochondria
b)rough endoplasmic reticulum
c)peroxisomes
d)lysosomes
e)smooth endoplasmic reticulum

Is it e?

For the first question, the correct answer is c) secretion of proteins. Malfunctioning of the Golgi apparatus can disrupt the proper sorting, processing, and packaging of proteins for secretion.

For the second question, the correct answer is d) plasma membrane. The symptoms described, including the lack of nutrients and improper concentrations of ions, suggest a problem with the plasma membrane, which is responsible for nutrient uptake, waste removal, and ion transport.

For the third question, the correct answer is c) peroxisomes. Low levels of lipids and high levels of intracellular toxins indicate that peroxisomes, which are involved in lipid metabolism and detoxification, are not functioning properly.

To check the answers for the first question, we look at the function of the Golgi apparatus. The Golgi apparatus is responsible for modifying, sorting, and packaging proteins and lipids for transport to their destination. Out of the given options, the cellular function most directly related to a malfunction of the Golgi apparatus is secretion of proteins (option c). Therefore, the correct answer is c) secretion of proteins.

To check the answers for the second question, we analyze the symptoms and laboratory results given. The lack of nutrients and molecular building blocks, improper intracellular concentrations of ions, and abnormal secretion of materials suggest a malfunction in cellular functions related to transport and regulation of molecules. Among the given options, the cellular structure most directly related to these functions is the plasma membrane (option d). Therefore, the correct answer is d) plasma membrane.

To check the answers for the third question, we examine the laboratory results provided. Low levels of lipids and high levels of intracellular toxins suggest a malfunction in cellular processes related to lipid metabolism and detoxification. Among the given options, the cellular organelle most directly related to these functions is the smooth endoplasmic reticulum (option e). Therefore, the correct answer is e) smooth endoplasmic reticulum.
