Building a Macromolecule Lab Assignment

Question

Title:

 

Objective(s):

 

Construct an Explanation:

Construct an explanation using what you learned in the lesson.

How are larger macromolecules formed from atoms of smaller macromolecules?

 

 

 

 

 

Create Each Molecule:

Once you create each molecule in the virtual lab simulation, take a screen shot of each molecule and place it below. Be sure to label the Carbons (C), Hydrogens (H), and Oxygens (O).

Glucose



Fructose

 

Sucrose

 

 

Revise your Explanation:

Revise your explanation. Be sure to use evidence from the virtual lab simulation.

How are larger macromolecules formed from atoms of smaller macromolecules?

Analysis Questions:

Analysis questions need to be answered using complete sentences. Some questions may require a longer explanation in paragraph form.

1. How did the carbon, hydrogen and oxygen atoms in glucose and fructose combine to form sucrose? Include in your description which atoms bonded together from fructose and glucose to form sucrose and which atoms reformed to create a water molecule.
2. What pieces of evidence from the virtual lab could you use to support the following claim?
3. Claim: Atoms from sugar molecules may combine with other elements via chemical reactions to form other large carbon-based molecules.
4. Make an inference about what happens to the matter and energy during the formation and breakdown of a complex carbohydrate molecules? When is energy stored or released?
5. Explain how sugar molecules combine with other elements to create amino acids. Why is this an essential process for living things?

Answer 1

How are larger macromolecules formed from atoms of smaller macromolecules?

Macromolecules, like carbohydrates and proteins, are polymer, which are long chains of the same repeating units. Those same repeating units are called Monomers.

For example, for Carbohydrates: the Monomer (single units) known as a monosaccharide, is called Glucose. If we link up those Glucose into a long chain now we created a Polymer called a Polysaccharide. These polysaccharides are your starches and cellulose. The monomer for proteins in called amino acids and when you link those up into a long chain, you create a polypeptide
