THE CELL HAS AT LEAST ONE ANODE (2) AND AT LEAST ONE CATODE (3), TO WHICH AN EXTERNAL CONSTANT POTENTIAL IS APPLIED IN SUCH A WAY A CONTINUOUS CURRENT GOES THROUGH THE ION DRIVING LIQUID. IN THE BOTTOM OF THE CELL IS A REST OF ION DRIVING LIQUID, IN WHICH THE ELECTRODES ARE ...
Learn what a chemical reaction is in biology with examples. Discover the different types of chemical reactions and the substances that boost them.
A chemical reaction is a process that always results in the interconversion of chemical substances. The substance or substances initially involved in a chemical reaction are called reactants. Chemical reactions are usually characterized by a chemical change, and they yield one or more products, which...
When a toad muscle is stretched 11 to 20% during the active phase of a twitch or a short tetanus, resisting strongly, the total heat (H) appearing in it up to the end of relaxation may be about equal to the total mechanical work (W) done during the stretch. Since all the work has...
where A is the stoichiometric matrix and r is a vector of rate expressions which describes the fluxes between different phases or fluxes due to chemical reactions. Those rate expressions are formulated in a thermodynamic consistent way and can be written as (2)rσπ,π′=kσπ,π′fσπ−...
In subject area:Chemistry Chemical reactivity is understood both as the ability of individual molecules to take part in various chemical reactions and the study of rates of such reactions, that is equilibrium and rate processes. From:Chemical Kinetics (Second Edition),2021 ...

Precision control of molecular activities and chemical reactions in live cells is a long-sought capability by life scientists. No existing technology can probe molecular targets in cells and simultaneously control the activities of only these targets at high spatial precision. We develop a real-time ...
Covalently locking interacting proteins in situ is an attractive strategy for addressing the challenge of identifying weak and transient protein interactions, yet it is demanding to execute chemical reactions in live systems in a biocompatible, specific, and autonomous manner. Harnessing proximity-enabled ...
Scientists have also teased out the chemical changes in the bacterium by studying different cells at various stages in a population of cells. This is not the same as studying the same cell over time, however. "We are studying the same individuals as opposed to studying the population. We wan...
