✓ Maintain cellular health by removal of toxic cellular components, removal of useless
organelles, termination of signal transduction, and signals cellular adaption



How does aging affect lysosomes

✓ Leads to progressive loss of lysosomal efficiency which declines the regenerative capacity
of organs and tissue



What functions do lysosomal components integrate?

✓ Nutrient abundance, energy levels, and cell stressors and will translate them into
instructions that regulate cellular metabolism toward either proliferation or inactivity



What is mitochondria responsible for?

✓ cellular respiration, cellular metabolism, and energy production



What does the inner membrane of mitochondria contain
