... that at behavioural low-light threshold, cockroach photoreceptors respond to moving gratings with single-photon absorption events known as ‘quantum bumps’ at or below the rate of 0.1 s −1 . By performing behavioural experiments and intracellular recordings from photoreceptors under identical stimulus conditions, we...

... intracellular molecular movement transport diffusion perfusion survival cytomatrix cytosol The cell is the crucible of life. In it, molecules move or are moved. Some are moving `randomly', driven by thermal energy; others are directed(convected). The same is true at the macro level. We have long...

... to maximally activated work, contrasting demands of intracellular homeostasis versus metabolic regulation obviously arise. Data accumulated over the last 3–4 decades now make it clear that the demands of homeostasis prevail: during rest–work transitions, metabolites such as ATP and O 2 are notably...

... analysis of pathways. This approach has served biology well and continues to be useful. Here, we consider the diffusion of small and large molecules in muscles and energy metabolism in the context of intracellular space. We find that in attempting to explain certain phenomena, a purely kinetic paradigm...
