which of the following statements regarding enzymes is true? (3 points) enzymes increase the rate of a reaction by making the re
ziro4ka [17]

Which is true about enzymes is: enzymes increase the rate of reactions by lowering the activation energy barrier.

Enzymes are chemical compounds in the form of proteins that act as biocatalysts which function to speed up reactions.

Enzymes work specifically, that is, they can only work on certain substrates by adjusting the shape of the substrate. Enzymes sensor with molecules for substrates to produce compounds through organic chemical reactions that require energy. Some of the reactions assisted by enzymes such as the breaking of large molecules into small ones or the binding of molecules into new molecules. Enzymes can do that because of the influence of the activation energy that every chemical reaction has.

Activation energy is the energy required to break down the reactants. The role of enzymes is to lower the activation energy limit needed to start reactions.

Onsidering that gluconeogenesis requires a net input of 4 atp equivalents compared to glycolysis, why would a cell utilize this
Pani-rosa [81]

The process by which organisms create sugars (specifically glucose) from non-carbohydrate precursors is known as gluconeogenesis.

  • The only energy source used by the brain, testes, erythrocytes, and renal medulla is glucose, with the exception of ketone bodies during fasting. There are three highly exergonic stages in glycolysis. Hexokinase, phosphofructokinase, and pyruvate kinase are among the enzymes involved in these additional regulatory stages. In biological processes, both forward and backward reactions are possible.
  • Similar to glycolysis, but with the process going the other way, is gluconeogenesis. Fructose-1,6-bP, glucose-6-P, and pyruvate all undergo fairly spontaneous conversions in the process of gluconeogenesis, which is why these reactions are tightly controlled.
  • For the organism to function properly, energy conservation is crucial. Gluconeogenesis is suppressed when there is an abundance of energy available.

Therefore, gluconeogenesis conserve more energy.
