Vocabulary

100

What is a monomer and a polymer?

Monomers are single molecular units and polymers are long chains of monomers.

200

Identify one similarity and one difference between carbohydrates and lipids.

Both carbohydrates and lipids are classified as molecules of life and both are organic compounds. Lipids are hydrophobic and have fatty acid chains attached to a glycerol. Carbohydrates consist of single sugar units (monosaccharides) which bond together to form polysaccharides.

300

What is the difference between hydrophilic and hydrophobic? Give an example for both.

Hydrophilic is "water-loving" and hydrophobic is "water-hating." Hydroxyl groups are hydrophilic and lipids are hydrophobic.

400

True or False? A fat consists of a three carbon backbone called glycine which is attached to three fatty acids.

False - glycerol and three fatty acids

500

__________ is a polysaccharide in plants that serves as a building material and ____________ are polysaccharides that consist of glucose monomers.

Cellulose & Starch

Organic Molecules

100

How many bonds can Carbon form with other atoms?

4

200

Describe the 3 different types of carbon backbones organic molecules can form.

Straight chained backbones are carbons bonded to one another in a line. Branched chained backbones are carbons that bond to one another and then extend (or branch) along the side. Carbon rings are backbones where carbons bond together and close into a ring.

300

Carbon based molecules are classified as ___________ molecules. Non-carbon based molecules such oxygen gas and ammonia are classified as ____________ molecules. Why?

Organic & inorganic. Because a carbon molecule is required for a molecule to be classified as organic.

400

Why is it called a __________ reaction when a water molecule is released? What happens when a water molecule is added?

Dehydration Reaction - because it involves removing (de-) a water (hydro-) molecule. When water is added, it is a hydrolysis reaction because water is used to break down the polymer.

500

Besides bonding with other carbon atoms, carbon can bond with other molecules called functional groups. Name all the functional groups we talked about in class and which functional group is hydrophilic?

Hydroxyl (hydrophlic) Carbonyl Carboxyl Amino

Carbohydrates

100

What is a carbohydrate?

Carbohydrates are organic compounds made up of sugar molecules.

200

Explain the difference between monosaccharide and a disaccharide.

Monosaccharides are single simple units of sugar. Disaccharides are "double sugars" or two monosaccharides.

300

Which statement is true? a. Simple sugars are made of polysaccharides b. Glycerol is made of fatty acids c. Polymers are made of monomers d. Amino acids are made of proteins

C. Polymers are made of monomers

400

Sucrose is a ___________ consisting of __________ and ___________ linked together.

Disaccharide, glucose, fructose

500

Describe the differences in structure of the 3 types of polysaccharides and what they do. Which polysaccharides are found in humans and which are found in plants?

Starch, cellulose, and glycogen all consist of glucose molecules, but Starch has a loopty loop chain structure, and serve as sugar storage for plants. Cellulose polysaccharides have a web like structure and are the building blocks for plants. Glycogen have a branched structure and serve as storage for humans.

Lipids

100

What property do lipids share?

They are hydrophobic

200

A steroid lipid molecule has a carbon skeleton that forms ________ fused rings.

4

300

True or false? Cholesterol is an essential molecule that surrounds our cells and are the starting points for other steroids.

True!

400

Steroids are also classified as lipids because they are __________. Estrogen and testosterone are examples of steroids naturally made in our bodies, but what is the only difference between these two hormones?

Steroids are lipids because they are hydrophobic. Testosterone has an oxygen double bonded to the four carbon rings and estrogen has a single bonded OH to its four carbon rings.

500

Describe the parts that makes up a fat and the specific functions for each fat.

Fat is made up of glycerol (a 3-carbon backbone) which is attached to a fatty acid (long hydrocarbon chains). Saturated fats are long straight carbon chains with single bonds and unsaturated fats are carbon chains with one double bond.
