How do chaperone proteins assist in protein folding?
✔✔Chaperone proteins help newly synthesized proteins fold correctly, preventing misfolding
and aggregation.
What is the function of the Golgi apparatus in cellular processes?
✔✔The Golgi apparatus modifies, sorts, and packages proteins and lipids for secretion or
delivery to other organelles.
How do tight junctions contribute to tissue integrity?
✔✔Tight junctions create a seal between adjacent cells, preventing the passage of molecules and
ions through the space between cells, thereby maintaining tissue integrity.

, What is the role of peroxisomes in cellular metabolism?
✔✔Peroxisomes are involved in the breakdown of long-chain fatty acids through beta-oxidation
and in the detoxification of hydrogen peroxide.
How does the cell cycle ensure genetic consistency during cell division?
✔✔The cell cycle includes checkpoints that monitor and regulate the progression of the cycle,
ensuring that DNA is accurately replicated and distributed to daughter cells.
What is the function of microtubules during cell division?
✔✔Microtubules form the mitotic spindle, which is crucial for separating chromosomes during
mitosis and meiosis.
How do signal transduction pathways influence cellular responses?
✔✔Signal transduction pathways transmit signals from the cell surface to the nucleus, leading to
changes in gene expression and subsequent cellular responses.
