1. Describe the relationship between nutrient deprivation and cellular function.
Nutrient deprivation has no significant effect on cellular function.
Nutrient deprivation impairs cellular metabolism and can lead to cell
injury due to lack of energy and essential building blocks.
Nutrient deprivation enhances cellular function by promoting
autophagy.
Nutrient deprivation only affects the structural integrity of cells.
2. What is the primary role of ATP in cell metabolism ?
It binds excess phosphates produced by cellular processes
It carries electrons between cellular processes
It is a key building block of metabolic enzymes
It carries energy between cellular processes
3. In sex-influenced characteristics
they are expressed differently in males and females
the trait has a higher penetrance in one of the sexes
all of these are true
they are inherited according to Mendel's principles
4. Describe the relationship between urate metabolism and the development of
gout.
, A disturbance in urate metabolism leads to elevated levels of uric
acid, which can crystallize in joints, causing gout.
Gout is caused by a deficiency in urate production, not metabolism.
Urate metabolism only affects kidney function, not joint health.
Urate metabolism is unrelated to joint health and does not affect gout.
5. Describe the significance of each stage of mitosis in the M phase.
Mitosis occurs only in prokaryotic cells.
Mitosis is a process that only occurs in plant cells.
Mitosis is only important for growth, not for cell repair.
Each stage of mitosis ensures accurate segregation of
chromosomes into daughter cells.
6. Necrosis refers to:
Oversupply of blood and oxygen
Deregulation of hormone secretions
Unregulated cell division
Tissue death
7. What is the definition of cachexia?
A metabolic disorder leading to increased appetite.
An inflammatory response to infection.
A condition involving excessive fat accumulation.
A syndrome characterized by severe weight loss and muscle
wasting.
,8. Describe the role of peroxisomes in cellular metabolism and how they
contribute to cellular health.
Peroxisomes are primarily involved in protein synthesis and do not
affect cellular health.
Peroxisomes are responsible for ATP production and do not
participate in detoxification.
Peroxisomes store genetic material and are not involved in
metabolism.
Peroxisomes play a crucial role in cellular metabolism by breaking
down fatty acids and detoxifying harmful substances, which helps
maintain cellular health.
9. Describe how polygenic traits differ from monogenic traits.
Polygenic traits are influenced by multiple genes, while monogenic
traits are determined by a single gene.
Polygenic traits can be dominant or recessive, while monogenic traits
cannot.
Polygenic traits are always visible, while monogenic traits are hidden.
Polygenic traits are only affected by environmental factors, whereas
monogenic traits are not.
10. What are the primary stages involved in the process of cell death?
Cellular communication, genetic mutation, and apoptosis.
Cellular adaptation, metabolic slowdown, and apoptosis.
Cellular injury, activation of death pathways, and eventual cell lysis.
Cell division, differentiation, and necrosis.
, 11. What are the four types of chromosomal abnormalities?
Aneuploidy, polyploidy, deletion, inversion
Deletion, duplication, inversion, translocation
Duplication, translocation, polyploidy, aneuploidy
Inversion, translocation, aneuploidy, duplication
12. Resting membrane potential is due to:
Negatively charged anions
K+ concentration & electrical gradients with slightly opened K+
channels
All
Na+/K+ pump
13. Describe the significance of cellular specialization in multicellular organisms.
Cellular specialization allows different cell types to perform unique
functions, contributing to the overall efficiency and complexity of
multicellular organisms.
Cellular specialization leads to the uniformity of cell functions across
an organism.
Cellular specialization is irrelevant in the context of multicellular
organisms.
Cellular specialization only occurs in prokaryotic cells.
14. Describe the significance of the plasma membrane in maintaining cellular
homeostasis.
The plasma membrane serves as a storage site for cellular waste.
