Biological Molecules
100
The basic unit of matter.
What is an atom?
100
These are the substances that react during a chemical reaction.
What are reactants?
100
These lower the activation energy needed for a chemical reaction.
What is a catalyst?
100
This property of water causes electrons to spend more time near the oxygen atom than the hydrogen atoms.
What is polarity?
100
All biological molecules contain this element.
What is carbon?
200
These make up the nucleus of an atom.
What are protons and neutrons?
200
These are formed after a chemical reaction.
What are products?
200
These are biological molecules that lower the activation energy for chemical reactions in organisms.
What are enzymes?
200
This property of water explains why water did not spill over the cup as pennies/paperclips were added to it.
What is cohesion?
200
Monomers are called monosaccharides. Polymers are called polysaccharide. Provide 'quick' energy. Glucose, sucrose, cellulose, and chitin are examples.
What are carbohydrates?
300
Chemistry is the study of this.
What is matter?
300
Water is essential for organisms because...
What is ... explain reasons.
300
These are factors that effect enzyme activity.
What are pH, temperature, substrate concentration, enzyme concentration?
300
Weak attractions that connect the slightly negative O of one molecules to the slightly positive H side of another.
What polar/hydrogen bonds?
300
Store a ton of energy. Fats, oils, waxes. Triglycerides are made of glycerols and fatty acids.
What are lipids?
400
Rank the types of bonds in order from strongest to weakest.
What is Ionic, Covalent, Hydrogen/Polar?
400
Carbon is important for organisms because...
What is ... explain reasons.
400
Hydrogen peroxide is the _____________ for catalase.
What is substrate?
400
Nonpolar molecules, including fats, oils and waxes, do not mix well with these types of molecules.
What are polar molecules?
400
Monomers are amino acids. Amino acids have an R-group, carboxyl group, and an amine group. They have a wide variety of functions, including enzymes.
What are proteins?
500
NaCl, C6H12O6, and H2O are all examples of these.
What are compounds?
500
This reaction breaks apart biological molecules using water in the process.
What is hydrolysis?
500
This occurs to enzymes when environmental conditions damage their structure.
What is they are denatured?
500
This reaction joins two monomers together, removing water in the process.
What is dehydration synthesis?
500
Monomer is called a nucleotide. Nucleotides are made of phosphate group, sugar and a base. DNA and RNA are examples.
What are nucleic acids?
