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?

To find the correct answer for each question, we should first understand the function of each cellular organelle mentioned and then analyze how a malfunction in each organelle would affect the given symptoms.

Let's go through each question and eliminate the incorrect answers:

1. 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

The Golgi apparatus is responsible for modifying, sorting, and packaging proteins for secretion. Therefore, a malfunction in the Golgi apparatus would most directly affect protein secretion. Thus, the correct answer is c) secretion of proteins.

2. 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 and molecular building blocks. 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

Based on the symptoms described, the most likely organelle to be malfunctioning is the plasma membrane. The plasma membrane regulates the movement of molecules into and out of the cell, controls ion concentrations, and facilitates cell secretion. Therefore, the correct answer is d) plasma membrane.

3. 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

The smooth endoplasmic reticulum (SER) is responsible for lipid synthesis and detoxification of drugs and toxins. If the SER is not functioning properly, it can lead to low levels of lipids and an accumulation of toxins within the cell. Therefore, the correct answer is e) smooth endoplasmic reticulum.

So, in summary, the correct answers are:
1. c) secretion of proteins
2. d) plasma membrane
3. e) smooth endoplasmic reticulum
