1. Describe the relationship between enzymes and substrates in the context of
cellular metabolism.
Enzymes break down substrates into products without any affinity.
Enzymes bind to substrates with high affinity to facilitate
biochemical reactions.
Enzymes have a low affinity for substrates to prevent rapid reactions.
Enzymes only interact with inhibitors, not substrates.
2. If a patient has a condition that affects the thymus gland, what impact might
this have on their immune system?
It may enhance the production of antibodies by B-cells.
It may have no impact on the immune system.
It may increase the production of red blood cells.
It may lead to a reduced number of functional T-cells,
compromising the immune response.
3. A patient develops skin cancer on the head and neck following years of
sunbathing. Which of the following cancers is most likely?
Lymphoma
Adenoma
Leukemia
Basal cell carcinoma
, 4. Describe the role of the kidneys in maintaining acid-base balance in the
human body.
The kidneys regulate acid-base balance by excreting or retaining
hydrogen ions and bicarbonate.
The kidneys filter waste products from the blood without affecting pH
levels.
The kidneys primarily regulate oxygen levels in the blood.
The kidneys produce hormones that directly affect blood pressure.
5. Describe the role of histones in the structure of DNA within the nucleus.
Histones facilitate the transport of RNA out of the nucleus.
Histones help package DNA into a compact, organized structure,
allowing for efficient storage and regulation of gene expression.
Histones are responsible for energy production in the mitochondria.
Histones are involved in protein synthesis in the cytoplasm.
6. If a patient is diagnosed with a benign tumor, what implications does this have
for their treatment plan compared to a malignant tumor?
The treatment plan may involve monitoring rather than aggressive
intervention.
The patient will require immediate chemotherapy.
The patient will need regular radiation therapy.
Surgery is always necessary to remove benign tumors.
7. Describe how fluid and electrolyte balance affects the treatment of
dehydration in elderly patients.
