What happens when a bond is formed in a macromolecule?

1 answer:

8 0

The bond energy is defined as equal to the amount of energy given out when the bond is made (or absorbed when that the bond is broken).

So when a bond is made, and the system cools to its original energy, the amount of energy given out, -DeltaH, is more or less equal to the bond energy.

Noticed that minus sign. For a process that releases heat, DeltaH is negative.

Internet to the rescue
Hope this helps!

Nataly_w [17]

Answer:

Stored water - gravitational energy

Water fall - kinetic energy

Turbine - kinetic energy

Powerlines - electric energy

Explanation:

Dams are used to store or hold water for hydroelectric power plants. This stored water which has gravitational energy is a form of potential energy.

When the water is left to fall and run fast through the turbine, the gravitational energy is transformed into kinetic energy which makes the turbine to spin.

As the turbine spins, kinetic energy that is produced also powers the shaft of the engine in the electric generator, which produces electricuty.

Kinetic energy is transformed to electric energy and transmitted along powerlines.

*See attachment below for labelled energy that is being transformed at several points.

Glucokinase and hexokinase in glycolysis

Delicious77 [7]

<h2>Answer:</h2>

Glucokinase or Hexokinase is a enzyme used at the first step of glycolysis.

<h2>Explanation:</h2>

Glucokinase is a Isoenzyme(enzymes which differs in the sequence of amino acids but catalyses the same reaction) of Hexokinase .
Glucokinase (hexokinase D) is present only in liver and pancreas whereas hexokinase is present in all cells.
In first step of glycolysis i.e formation of glucose-6-phosphate from glucose is completed with the help of hexokinase. In this step a ATP molecule is consumed i.e ATP is converted to ADP

Result: Glucokinase and hexokinase are used in the first step of glycolysis.
