Question

Quizplus · Accepted Answer

All the options listed (Hsp, Calpains, Cathepsin, Proteosome) are directly involved in protein turnover. Hsps (Heat shock proteins) assist in protein folding and protection against stress. Calpains are calcium-dependent cysteine proteases involved in various cellular processes, including protein degradation. Cathepsins are lysosomal proteases that play a role in protein turnover. Proteasomes are protein complexes that degrade unneeded or damaged proteins by proteolysis, a chemical reaction that breaks peptide bonds.
