Biological clocks: how does our body know that time goes by?
WEBAug 31, 2023 · A biological clock is a mechanism internal to organisms that, in the absence of an environmental signal, operates at its own frequency. The regular alternation of day...
Circadian Rhythms - National Institute of General Medical Sciences
WEBDec 11, 2023 · The system that regulates an organism’s innate sense of time and controls circadian rhythms is called a biological clock. It’s composed of proteins encoded by thousands of genes that switch on and off in a specific order. A master clock coordinates all the biological clocks in an organism.

WEBFeb 2, 2022 · Nearly all living organisms have an inherent time-keeping mechanism, an endogenous clock that synchronizes and controls their daily biological processes. The daily oscillations directed by endogenous clocks are circadian rhythms, one of the essential characteristics of all living organisms [ 1 ].
