Morphological changes of mitochondria-related to apoptosis during postmortem aging of beef muscles

Effect of mitochondrial calcium homeostasis-mediated endogenous enzyme activation on tenderness of beef muscle based on MCU modulators

“…The primary organelle that produces reactive oxygen species (ROS) is the mitochondria, which is also the organelle that is most frequently targeted for attack ( Ding, Wei, Liu, Zhang, & Huang, 2022 ). ROS generated by single electron transfer could result in mitochondrial membrane swelling or loss of membrane potential after animal bleeding ( Liu et al, 2023 ; Zhang, Ma, & Kim, 2020 ). Cytochrome c is released from the mitochondria to the cytoplasm to bind Apaf-1, dATP/ATP and pro-caspase-9 when mitochondrial permeability increases, triggering executioner caspase activation ( Green, 2005 ).…”
