Which of the following is true about chemical energy?

A. Chemical energy can be stored more efficiently as glucose than it can be as ATP.

B. Chemical energy is stored when bonds in ATP are broken to form ADP.

C. Chemical energy is released when bonds in ADP are broken to form ATP.

D. Chemical energy can only be stored as ADP.

Answer: A. Chemical energy can be stored more efficiently as glucose than it can be as ATP.

Chemical energy is formed or produced during the course of a chemical reaction or process. Glucose is the body’s way of storing chemical energy, and this glucose is stable and is used for all the metabolic processes that take place in the body, whereas ATP is more easily broken down.

When ATP is converted to ADP, chemical energy is released, not stored. ADP cannot be broken down into ATP because ATP is more complex than ADP. Also, ADP is not the only way that chemical energy is stored (ATP and glucose are other ways).

Math Calculus — AID—

Total time spent: 4 hours 15 minutes (it is equivalent to 255 minutes). Let the flight time from Paris to Glasgow be X. Then the flight time from Glasgow to Paris will be (X+10). We have an equation with one unknown variable: X + 45 + (X+10) = 255 ⇒ X = 100 So the […]

How does 3D printing work?

There are three different ways 3D printers work but they all rely on the printer converting a design into individual 2D slices which are then combined to make the final 3D object. The first method uses a pool of chemicals that turns solid when light, typically a UV laser, is shone on to it. The […]

Cigarette smoking causes emphysema.

Nearly everyone knows that smoking causes lung cancer, but did you know that smoking causes a number of other serious lung diseases? These include chronic bronchitis and emphysema, collectively known as chronic obstructive pulmonary disease (COPD). COPD is the fourth largest killer of Australians and smoking is the most important risk factor for COPD. When […]
