Question

directions: analyze model 1 and answer the questions that follow. model 1: macromolecules are made from repeating smaller monomer units such as glucose, glycerol and glycine. 4. a complete carbohydrate is a macromolecule. this means that it is a large or small molecule. (circle one) 5. use model 1 to show which atoms are present in each type of molecule by listing the symbol for each atom included (an atom = element in the molecule). carbohydrate has been done for you. a. carbohydrate: c h o b. lipid: __________ c. protein: ________ 6. list 3 similarities between the 3 types of macromolecules. a. ________ b. ________ c. ________ 7. list 3 differences between the 3 types of macromolecules. a. ________ b. ________ c. __________ during chemical reactions, the bonds in molecules are continually broken and reformed. when bonds are broken, energy is released called atp. atp molecules are energy molecules that allow cells to do the work needed to keep the organism alive and functioning. when bonds are broken, energy is released and can be used as a source of energy. the more carbon atoms there are in a molecule, the more energy that molecule can provide to the organism when it is used as food when the bonds are broken. 8. using the information from above and model 1, is a carbohydrate, lipid, or a protein more likely to be a good source of energy for an organism? use comparative data to support your answer.

Explanation:

Step1: Answer question 4

A macromolecule is large.
large

Step2: Answer question 5b

Inspect lipid structure.
CHO

Step3: Answer question 5c

Inspect protein structure.
CHON

Step4: Answer question 6

Find similarities.
a. Made of monomers. b. Contain carbon. c. Essential to life.

Step5: Answer question 7

Find differences.
a. Different monomers. b. Protein has nitrogen. c. Lipid has most C - H bonds.

Step6: Answer question 8

Lipid has more C atoms usually.
Lipid, as it generally has more carbon atoms and can release more energy when bonds break.
