The standard free energy change of the glycolytic pathway to pyruvate is -79.9 kj/mol, while the standard free energy change associated with gluconeogenesis from pyruvate is -42.7 kj/mol. what would the standard free energy change be for a direct reversal of the glycolytic pathway?

122.7 kj/mol

Explanation:

This is purely theorical because it is not possible to accomplish the reversed pathway of the gycolytic pathway, but you would only need the same amount of energy but in reverse, this is in theory, in order to reverse the pathway. Standard free enegy is the amount of energy needed to create one mole of a given substance in its most stable form.

a plastic spoon that has a temperature of 78° f is placed into a bowl of soup that has a temperature of 84° f. which of these correctly describes what will happen?

energy as heat moves from the soup to the spoon.

estuaries are the partially enclosed coastal bodies of brackish water formed at the mouth of sea where river meets an ocean. it is a transition zone between river and sea water so estuaries are influenced to both marine environment such as tides, waves and to riverine such as flow of fresh water and sediments. the mixing of sea and fresh water provide high level of nutrients, making estuaries a high product habitats.

many estuaries suffers degradation from a variety of human activities like erosion from deforestation, overgrazing, overfishing, drainage and eutrophication.

so from the above statement answers will be

1. false as estuaries are formed due to both brackish and freshwater.

2.true, due to high productivity estuaries are breeding ground for many marine species.

3. direct and indirect activities of man that contribute to pollution and deposition of sediments.
