Biology Chapter 2

Carbohydrate - molecules composed of carbon, hydrogen, and oxygen - include sugar and starches. - CHO, 1:2:1 Ratio, C 6 H 12 O 6 d
What are some examples of carbohydrates - Pasta - Bread - Wheat
Monosaccharides - simple sugars in carbohydrat
How many simple sugars are in a carbohydrate - five or six carbon atoms
Monomers Each subunit in the complete molecule
Polymer Large molecule, or a macro molecule, made of many monomers bonded together.
Lipids -nonpolar molecules that include fats, oils, and cholesterol. -most lipids contain chains of carbon atoms bonded to oxygen and hydrogen atoms. - Some lipids are broken down as a source of usable energy for cell
What is the job of lipids store energy
What are fatty acids are chains of carbon atoms bonded to hydrogen atoms.
Protein - is a polymer made of monomers called amino acids. - CHON
What is the job of protein - Build, Repair, Maintain
Amino acids are molecules that contain carbon, hydrogen, oxygen, and nitrogen, and sometimes sulfur.
How many amino acids are used to build proteins Organisms use 20 different amino acids. Body can make 12 of the amino acids others come from foods such as meat, beans, and nuts
Nucleic Acids - are polymers that are made up of monomers called nucleo tides - CHONP - Carbon, Hydrogen, Oxygen, Nitrogen, Phosphorus
Nucleotides - composed of sugar - phosphate group - DNA & RNA.
What is the job of Nucleic Acids - Work together to make proteins.
What is the relationship between a polymer and a monomer - Monomers are sub units many of these monomers make up a large macro molecule called polymers
Explain how both nucleic acids and proteins are polymers. Be sure to describe the monomers that make up the polymers - Both are made up of monomers (protein - amino acids) (nucleic acids- nucleotide)
How are carbohydrates and lipids similar? How are they different?

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
