What do most Calories in our food come from? Fat and Carbohydrates
What is another name for Carbohydrates? Sugars
Describe a Monosaccharide 1 carbohydrate. (single-unit sugar)
Describe a Disaccharide 2 monosaccharides (carbohydrates) linked together by dehydration reaction
Describe a Polysaccharide More than 3 carbohydrates (polymers of monosaccharides) linked together by dehydration reaction
What does Monomer mean? one part
What does Polymer mean? many parts
What are 2 examples of monosaccharides? glucose and fructose
what are 2 examples of disaccharides? lactose and sucrose
what are 4 examples of polysaccharides? starch, glycogen, chitin and cellulose
What are the main fuel for cellular work? Monosaccharides
What is the process of making ATP? cellular respiration
What is the organelle that makes ATP through cellular respiration? the Mitochondria
What is the equation for cellular respiration? C6H12O6 + O2 --> H2O + CO2 + ATP = Cellular Respiration
What are the two main types of energy? Potential energy and Kinetic energy
What is Kinetic energy? The energy of motion. ex: Heat
What is potential energy? Stored energy. ex: chemical reactions
What does ATP stand for? Adenosine Triphosphate
What is the purpose of ATP? to do cellular work
What is a Macromolecule? "gigantic" molecules (carbohydrates, proteins, lipids, nucleic acids)
Describe Dehydration Reaction The loss of H2O when two molecules join
What do cells do to link monomers together to make polymers? Dehydration Reaction
What does hydrolysis mean? "to break with water" Cells break bonds between monomers by adding water to them. (this is to break down polymers (think of digestion)) It is the opposite of dehydration reaction

math for calories grams X degrees = calories
What is specific heat? the heat required to raise the temperature of a substance by a given amount (usually 1 degree)
functions of monosaccharides main fuel molecules for cellular work
functions of disaccharides sugars that we consume for QUICK ENERGY (breaks down into monosaccharides by hydrolysis)
