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?

Since Golgi bodies create lysosomes which are used in cellular digestion, b is correct.

Since A is Mitochondria and that is used for energy production (ATP) and the question asks about nutrients, A is incorrect. Break down of macromolecules releases nutrients. Lysosomes break down macromolecules so that is the correct answer.

Peroxisomes breakdown long fatty acid chains. If they are overactive, there would be a low lipid level.

A company seeks to develop an herbicide that kills plants by directly interfering ( at the cellular level ) with plants' ability to maintain turtle pressure. An herbicide could accomplish this by disrupting the membrane of

A) chloroplast
B) chormplasts
C) amyloplasts
D) central vacuoles
E) mitochondria

Is it c ?

For the first question, the correct answer is actually c) secretion of proteins. The Golgi apparatus is responsible for modifying, sorting, and packaging proteins into vesicles for secretion.

For the second question, the correct answer is d) plasma membrane. The symptoms described, such as improper intracellular ion concentrations and abnormal secretion, suggest a problem with the plasma membrane, which regulates the movement of substances in and out of the cell.

For the third question, the correct answer is b) rough endoplasmic reticulum. The rough ER is involved in the synthesis and modification of proteins, including the production of lipids. A malfunction in the rough ER can lead to low levels of lipids and disrupted cellular functions.

So, the correct answers are:
1) c) secretion of proteins
2) d) plasma membrane
3) b) rough endoplasmic reticulum

To check the answers for the "choose the best answer" questions, we need to understand the functions of the cellular structures mentioned and determine which one is most directly related to the given symptoms or laboratory results.

1. Which of the following cellular functions would be most directly related to a malfunction of the Golgi apparatus?
The Golgi apparatus is responsible for modifying, sorting, and packaging proteins before they are transported to their final destinations within or outside the cell. Based on this function, the correct answer would be (c) secretion of proteins. Malfunction of the Golgi apparatus can lead to improper packaging and secretion of proteins, affecting cellular function.

2. 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. These laboratory results can best be explained if which cellular structure is not functioning properly?
Based on the given symptoms and laboratory results, mitochondrial dysfunction seems to be the most likely explanation. Mitochondria are responsible for energy production in the form of ATP, and the lack of nutrients and molecular building blocks suggests a deficiency in ATP production. Additionally, the impaired secretion of materials and improper intracellular concentrations of ions can also be attributed to dysfunctional mitochondria. Therefore, the correct answer would be (a) mitochondria.

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. Based on this information, the malfunction of which cellular organelle is the most likely explanation?
The smooth endoplasmic reticulum (SER) is responsible for lipid synthesis and detoxification processes in cells. A malfunction of the SER can lead to reduced lipid levels and an accumulation of intracellular toxins. Therefore, the correct answer would be (e) smooth endoplasmic reticulum.

So, the correct answers are:
1. Golgi apparatus malfunction: (c) secretion of proteins.
2. Mitochondrial dysfunction: (a) mitochondria.
3. Malfunctioning cellular organelle: (e) smooth endoplasmic reticulum.
