Storage Root Yield

Storage root yield is the quantity or mass of harvestable storage roots produced by a plant, an important measure of productivity in crops such as cassava, sweet potato, and yams. It depends on how effectively plants convert photosynthetic carbon into carbohydrates and allocate them to specialized roots, where sugars and starch accumulate as the roots enlarge; water, nutrients, genotype, and growing conditions influence this process. Measuring storage root yield helps researchers evaluate crop performance, study source–sink relationships, and identify traits linked to food security, biomass production, and improved agricultural resilience.

ATP Yield

Cellular respiration produces 30 - 32 ATP per glucose molecule. Although most of the ATP results from oxidative phosphorylation and the electron transport chain (ETC), 4 ATP are gained beforehand (2 from glycolysis and 2 from the citric acid cycle). The ETC is embedded in the inner mitochondrial membrane and is comprised of four main protein complexes and an ATP synthase. NADH and FADH2 pass electrons to these complexes, which pump protons into the intermembrane space. This distribution of...

A schema is a mental framework that helps individuals organize and interpret information. Schemata, formed from previous experiences, influence how we process new information: how we encode it, the inferences we make, and how we retrieve it. For instance, a schema for what a typical classroom looks like might include desks, a teacher's desk, a whiteboard, and students in such an environment. This expectation helps us quickly understand and navigate new classrooms without needing to analyze each...

The theoretical yield of a reaction is the amount of product estimated to form based on the stoichiometry of the balanced chemical equation. The theoretical yield assumes the complete conversion of the limiting reactant into the desired product. The amount of product that is obtained by performing the reaction is called the actual yield, and it may be less than or (very rarely) equal to the theoretical yield. Percent Yield In the case of chemical reactions, the actual yield of the product is...

Source: Robert M. Rioux & Taslima A. Zaman, Pennsylvania State University, University Park, PA While the use of various chemicals in experimental research is essential, it is also important to safely store and maintain them as a part of the Environmental, Health and Safety (EHS) program. The properties of chemicals and their reactivity vary broadly and if chemicals are not managed, stored, and labeled properly, they can have harmful or even destructive consequences such as toxic fume...
