Building Blocks of Macromolecules

Macromolecules breakdown

QOHS

​Carbohydrates

• provide quick energy to the body through glucose, a simple sugar

• ​larger carbohydrates are made of simple sugars called monosaccharides (like glucose)

• ​glucose is broken down for energy and to make new things in the body

• examples are sugars and starches

• ​contain C, H, O

Multiple Select

Carbohydrates are made of (select all that apply)

• Carbon

• Hydrogen

• Oxygen

• Nitrogen

• Phosphorous

Multiple Choice

The monomers or building blocks of carbohydrates are

• amino acids

• monosaccharides

• nucleotides

• fatty acids and glycerol

Multiple Choice

Carbohydrates are important for life because

• they make up cell membranes

• they code for genetic information

• they regulate cell processes and are important for muscle development

• they are a main source of energy

Multiple Select

We find carbohydrates in foods like (select all that apply)

​Lipids

• ​make up the cell membranes, provide long-term energy, and include some hormones

• made of glycerol and fatty acids

• examples are fats and steroids

• ​contain C, H, O

• they make up cell membranes

• they code for genetic information

• they regulate cell processes and are important for muscle development

• they are a main source of energy

​Why do we need to eat?!

• Digestion breaks food down into useful nutrients, so the body can use those nutrients to make the macromolecules it needs

• Cells also use these nutrients to perform cellular respiration, which gives the body energy to do work (like walk up all the stairs to biology!)

• The nutrients move into the bloodstream (absorption) and then can be transported throughout the body
