Metabolism, respiration

The dicarboximides inhibit spore germination and cause increased branching, swelling and lysis of germ tubes and hyphal tips. Effects on cell division have been reported but no major inhibition of nucleic acid metabolism, respiration, protein or lipid synthesis has been observed.

Plants also undergo the same metabolic respiration processes, whereby the plant energy sources such as sugars undergo respiration to yield carbon dioxide and water. This is accompanied by transpiration, the elimination of water vapor to the atmosphere via the leaves, as derived from soil water and its nutrients, and also from respiration. (And which influences climate, notably via the tropical rain forests.) More details about plant biochemistry are furnished in the standard references and textbooks, e.g., in Plant Physiology by Frank B. Salisbury and Cleon W. Ross (1985). 

Therefore, G. sulfurreducens biofilm electron transfer is generally described as complete acetate oxidation to carbon dioxide, protons, and electrons in which electron transfer outside the cells is the rate-limiting step. The mass transfer of protons and carbon dioxide affects pH buffering and has been shown to affect the biofilm. Throughout the rest of this chapter, we consider only electron transfer and pH effects, ignoring changes in metabolic activity of the biofilm. Only the metabolic respiration rate, approximated by the current measured at the biofilm electrode, is considered. This does not mean that changes in metabolic activity are less important. We refer the readers to Chapter 2 for more information on G. sulfurreducens metabolism. 

Fluctuations in viscosity are real and common facts of chonical processes. As a polymer increases in chain length, the viscosity will surely increase— and not always in a manner resembling linearity. In the example of sugar solutions (sugar syrup) in a fermentation process, as the sugar is consumed by metabolic respiration, the viscosity will decrease. These changes affect, at a minimum, the flow characteristics, density, and pressure of the solution. These types of changes must be anticipated for an analytical method to be effective. 

Plant toxins which affect contractions of the heart muscle or metabolic respiration processes are associated with acute poisoning in mammals. Two groups of glycosides (cyanogenic glycosides and cardiac glycosides) are present in plants commonly available to grazing animals and are responsible for livestock losses.
