1) if the molecule glucose were broken down, would it provide all of the elements needed to assemble lipids, nucleus acids or proteins? explain. 2) do sugar molecules provide all the elements needed to make the four types of macromolecules ? plz w these

1. Answer is "it provides all the elements for lipids".

The elements of glucose are carbon, hydrogen and oxygen. Hence, if the molecule glucose were broken down, those elements are released.

The elements of lipids are same as glucose. But sometimes lipids contain sulfur and phosphorous.

In proteins there is nitrogen as element other than carbon, hydrogen and oxygen.

Nucleic acids also have carbon, hydrogen, oxygen, nitrogen and phosphorus as elements.

Hence, glucose molecule cannot provide all the elements for proteins and nucleic acids but can provide elements for most of lipids.

2. Answer is “NO”.  

The four types of macromolecules are carbohydrates, lipids, proteins and nucleic acids. Elements of those macromolecules are as follows.

Carbohydrates - carbon, hydrogen, and oxygen

Lipids - carbon, hydrogen, oxygen sometimes nitrogen and phosphorus.

Proteins - carbon, hydrogen, oxygen and nitrogen sometimes sulfur and selenium.

Nucleic acids - carbon, hydrogen, oxygen, nitrogen and phosphorus.

Sugars are also type of carbohydrates. Hence, sugars can provide only carbon, hydrogen, and oxygen as the elements. Therefore, sugars cannot provide all the elements that needed to make four types of macromolecules. But sugars can provide elements to make carbohydrates and most of lipids.

genetic variation will increase because of a new habitat and food source.
