Rank these reactions from least to most energetically favorable.
mafiozo [28]

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.

What type of
Cerrena [4.2K]

Answer:

Logistic growth

Explanation:

J-curve can be easily eliminated as it is just a J shaped graph, simple enough right?

Linear growth is just a linear line... so that's not it either!

Now we have logistic growth, which fits the graph perfectly!

And here's the trick option, the carrying capacity is a part of the logistic growth graph, but NOT the function we are seeing on the screen right now. See the diagram attached below.

Therefore answer is C, logistic growth!

Hope this helps, please ask any questions you have down in the comment section below, I'll be more than happy to answer them!

Edit: Original graph is a PNG therefore blends right into the background.
