Topic: enzyme activity

Clarice D. Aiello examines evidence that quantum effects influence biological function, including magnetic sensing used in animal navigation, cellular metabolism and enzyme activity, and the capture of light energy in photosynthesis. The talk reviews proposed biophysical mechanisms and their implications for human, plant and environmental biology, while considering the difficulty of connecting observations from nanometre scales to whole organisms. A central question is whether quantum mechanics can be established or ruled out as the explanation for physiologically relevant effects, and whether

Gangliosides, complex membrane glycosphingolipids, engage in a variety of inter- and intracellular interactions, and play a crucial role in the pathogenesis of various neurological and neurodegenerative diseases. Another membrane constituent, leptin receptor (LepR), modulates feeding behavior by influencing signaling and integration in many regions of the central nervous system. Studies show that a-series gangliosides alter leptin activity by interacting with LepR The redistribution of gangliosides can also influence the regulation of the Na⁺,K⁺-ATPase (NKA) function, whereas leptin pathways c
