What is the role of peroxisomes in the cell?
✔✔ Peroxisomes break down fatty acids and detoxify harmful substances by producing and
degrading hydrogen peroxide.
How do plant cells use vacuoles differently from animal cells?
✔✔ Plant cells use vacuoles for storing nutrients, waste products, and providing structural
support through turgor pressure, whereas animal cells have smaller vacuoles with less prominent
roles.
What is the importance of DNA methylation in gene expression?
✔✔ DNA methylation can silence gene expression by preventing transcription factors from
accessing the DNA.

,How do proteins achieve their three-dimensional structure?
✔✔ Proteins fold into their three-dimensional structure through interactions between amino
acids, including hydrogen bonds, ionic bonds, and hydrophobic interactions.
What is the significance of telomeres in cellular aging?
✔✔ Telomeres protect chromosome ends from deterioration or fusion with neighboring
chromosomes, and their shortening is associated with cellular aging and senescence.
How do lysosomes contribute to cellular homeostasis?
✔✔ Lysosomes digest and recycle cellular waste and damaged organelles, helping maintain
cellular balance and functionality.
What role do integrins play in cell adhesion?
✔✔ Integrins are cell surface receptors that facilitate attachment to the extracellular matrix and
play a role in cell signaling and migration.

, How does cellular respiration differ in prokaryotic cells compared to eukaryotic cells?
✔✔ In prokaryotic cells, cellular respiration occurs in the cytoplasm and plasma membrane,
while in eukaryotic cells, it primarily takes place in the mitochondria.
What mechanisms ensure that cells maintain their internal pH?
✔✔ Cells use buffer systems, active transport pumps, and compartmentalization to regulate and
maintain internal pH levels.
How does the process of autophagy contribute to cell health?
✔✔ Autophagy involves the degradation and recycling of cellular components, helping to
remove damaged organelles and proteins, which supports cell health and longevity.
By definition, an acid is a substance that.. ✔✔causes the H+ ion concentration of a solution to
increase
