Atoms are the smallest building blocks of elements having the same chemical and physical properties of that specific element. Atoms combine together with the help of electrons, to form a little more complex entity like the molecules, crystals, liquids etc. Some molecules combine together to form a more complex entity like the DNA which is the most complex molecule. The whole universe is made out of these simple building blocks, including the human body.
Hazardous Chemical” Simple Definition -- elements, chemical compounds, or. mixtures of elements and/or compounds which poses potential risk to safety or health. Regulatory Definition - means any chemical which. presents a physical hazard or a health hazard.
Laboratory is a place to information about the hazards that are associated with a compound.
A. there is a change in Genetic frequency
Answer:
From least to most energetically favorable, the reactions are:
Glucose to Glucose-6-P (least) ; Glucose-6-P to Fructose-6-P; ATP to ADP and Pi; PEP to pyruvate (most favorable)
Explanation:
ΔG represents the free energy change that occurs during a chemical reaction. A reaction with negative free energy change is exergonic and spontaneous. Negative free energy change represents the fact that reactants have more free energy than products. The excess of the energy is released during the reaction and makes it a spontaneous process.
q`On the other hand, a reaction with positive free energy change is endothermic and non-spontaneous. These thermodynamically unfavorable reactions are coupled with other exergonic reactions to make them occur.
Among the given example, PEP to pyruvate has the highest negative free energy change (−14.8 kcal/mol) and therefore, is energetically most favorable. On the other hand, "Glucose to Glucose-6-P" has the highest positive free energy charge (+3.3 kcal/mol) making it energetically the most unfavorable reaction.
