Drag the correct elements to each macromolecule:

Carbohydrates = ​ ​ ​ (a)   also written as ​ (b)  

Lipids = ​ (c)  

Proteins = ​ (d)  

Nucleic Acids = ​ (e)  

• CHO (1:2:1)
• CHO (1:2) with O way less
• CHON
• CHONP

In a cell membrane, proteins are depicted in blue. Despite their varied specific roles, they all -

• create molecules that communicate with other cells

• assist the cell in interacting with its surrounding environment

• eliminate large particles from the cell's cytoplasm

• halt biochemical reactions within the cell

​ ​ (a)   are single units/subunits of ​ (b)   , which are chains of the subunits.

• Monomers
• Polymers

What are the biomolecules that are not soluble in water because they are hydrophobic?
