what is the function of circuit breakers and fuses?​

Answers

Answer:

Fuses and Circuit Breakers both serve the same purpose – which is to protect electrical circuits by preventing overloads that can cause fires. They both interrupt the flow of electricity, but in very different ways from each other. While a fuse is made of a piece of metal that melts when overheated, circuit breakers on the other hand, have internal switch mechanisms that can be tripped by an unsafe surge of electricity.

Fuses can be quicker for interrupting the flow of power, but when they melt they must be replaced; circuit breakers on the other hand just need to be reset. When comparing the two, we’ll take a look at some of the major advantages and disadvantages between fuses and circuit breakers to distinguish between them.

Answers

The correct order of glycolysis reactions is:

Two phosphate groups from two ATP molecules are joined to glucose.Two NADP molecules are converted into two NADH molecules.A six-carbon molecule is broken down into two three-carbon molecules.Two three-carbon molecules are converted into two molecules of pyruvate as four  molecules of ATP are produced.

During glycolysis, the glucose molecule is converted to Glucose-6-phosphate as a result of phosphorylation. The phosphate group from ATP is joined to the glucose molecule by an enzyme known as hexokinase.

The glucose-6-phosphate then undergoes isomerization to become fructose-6-phosphate which is then phosphorylated again by the hexokinase enzyme to become fructose-1,6-biphosphate.

An aldolase enzyme converts fructose-1,6-biphosphate to one molecule of glyceraldehyde-3-phosphate and one molecule of dihydroxyacetone phosphate. The latter is then converted to another molecule of glyceraldehyde-3-phosphate.

A dehydrogenase enzyme converts glyceraldehyde-3-phosphate to 1,3-bisphosphoglycerate with NADH being generated from the reduction of NAD+.

A kinase enzyme then converts 1,3-bisphosphoglycerate to 3-phosphoglycerate with ATP being generated from ADP. A mutase enzyme quickly converts the 3-phosphoglycerate to 2-phosphoglycerate while an enolase enzyme converts the latter to phosphoenolpyruvate.

Finally, a pyruvate kinase enzyme converts phosphoenolpyruvate to pyruvate with another ATP being generated.
