Explain why organic molecules (rather than inorganic molecules) are the building blocks of life. Organic molecules have enough variety

Explain why there is such a wide variety of organic compounds. Because organic compounds contain carbon C can bond to many other atoms C can bond to itself

Identify this organic compound and state its chemical formula. Glucose C6H12O6

State whether glucose is a monomer or a polymer, and defend your answer. Atoms joined together Small NOT monomers joined together

Explain how A becomes B. Polymerization A B

Identify the four organic compounds found in living things. Lipid Nucleic Acid Fat Cell Protein Muscle Carbohydrate Blood

Identify the four organic compounds found in living things. Protein Nucleic Acid Chlorophyll Cell Lipid Oil Carbohydrate Wood

State whether or not the molecule below is a carbohydrate, and defend your answer. NOT a carbohydrate C, H, O atoms are not in a 1:2:1 ratio

State the function of carbohydrates in ALL living things. Main source of energy Eating Photosynthesis

By breaking the bonds between atoms Explain how living things get energy from carbohydrates. By breaking the bonds between atoms Energy

State the second function of carbohydrates (plants only). Build structure Basically, carbohydrates have two functions. The first, and most important function, is energy. Living things use carbohydrates as their main source of energy. Right now, your body is breaking down the carbohydrates you ate for breakfast/lunch, releasing the energy that was holding the molecule together and using this energy to carry out life proccesses. The second function of carbohydrates, which is found mostly in plants, is structure. Plants (and some animals) use carbohydrates to build structures, such as stems, leaves and bark. BARK DEMO. This bark is made from a type of carbohydrate called cellulose. The stringy stuff in celery is also cellulose. Cellulose is the principal component of wood and paper. Right now, you are writing on cellulose, a carbohydrate.

Identify B as a monosaccharide or a polysaccharide, and defend your answer. Many sugars B

Explain how the carbohydrates below are similar. Both polysaccharides Both made from glucose Starch Cellulose

Explain how plants use starch, and give a real-life example. Store extra glucose Potato

Explain how plants use cellulose, and give a real-life example. Build structure Wood

ATOMS MONOSACCHARIDE POLYSACCHARIDE GLUCOSE STARCH Identify the monosaccharide and polysaccharide shown in the diagram below. H C C O H C H O C O O C H H H C O ATOMS MONOSACCHARIDE POLYSACCHARIDE GLUCOSE STARCH

Identify the organic compound below, and defend your answer. Lipid Mostly C and H atoms

Hibernating bear (fat) State the main function of lipids in living things. Storing energy Hibernating bear (fat) Coconut (oil)

Explain why lipid molecules are good at storing energy. Lots of bonds

Explain what it means to say that lipids are “not soluble.” Don’t dissolve in water

Explain how living things make use of the fact that lipids are not soluble. They use lipids to form waterproof coverings Duck feathers Waxy leaves Steroids

State the third function of lipids in living things. Forms cell membranes

Explain how lipids are different from carbohydrates in terms of their structure. Lipids have no monomers or polymers Lipids Carbohydrates
