They are produced by virtually all cells involved in innate and adaptive immunity but especially by T- helper (Th) lymphocytes. The activation of cytokine-producing cells triggers them to synthesize and secrete their cytokines. The cytokines in turn are then able to bind to specific cytokine receptors on other cells of the immune system and influence their activity in some manner. Cytokines are"

"Oxidative phosphorylation is a process in our cells where electrons are transferred from NADH and FADH2 (generated during the Krebs cycle) to oxygen (thereby reducing it and also generating ATP) across several protein complexes in the mitochondria known as the electron transport chain. The stepwise passing of electrons from one complex to the next complex helps generate a H+ gradient across the inner mitochondrial membrane which eventually powers ATP synthesis via ATP synthase. #biologytok #biologyclass #apbio #apbiology #biologymemes #premed #fyp #biochem #mitochondria #CapCut"

Chromosome replication begins with the binding of an initiator protein (DnaA) to an AT-rich sequence (for example TTATCCACA in E. coli) in the OriC and melts (disrupts the hydrogen bonding between) the two strands.
