Atoms
The basic unit of matter.
What is an atom?
These are the substances that react during a chemical reaction.
What are reactants?
These lower the activation energy needed for a chemical reaction.
What is a catalyst?
This property of water causes electrons to spend more time near the oxygen atom than the hydrogen atoms.
What is polarity?
All biological molecules contain this element.
What is carbon?
These make up the nucleus of an atom.
What are protons and neutrons?
These are formed after a chemical reaction.
What are products?
These are biological molecules that lower the activation energy for chemical reactions in organisms.
What are enzymes?
This property of water explains why water did not spill over the cup as pennies/paperclips were added to it.
What is cohesion?
Monomers are called monosaccharides. Polymers are called polysaccharide. Provide 'quick' energy. Glucose, sucrose, cellulose, and chitin are examples.
What are carbohydrates?
What is an ionic bond?
Water is essential for organisms because...
What is ... explain reasons.
These are factors that effect enzyme activity.
What are pH, temperature, substrate concentration, enzyme concentration?
Weak attractions that connect the slightly negative O of one molecules to the slightly positive H side of another.
What polar/hydrogen bonds?
Store a ton of energy. Fats, oils, waxes. Triglycerides are made of glycerols and fatty acids.
What are lipids?
This type of bond forms between 2 non-metals and the elements share valence electrons.
What is a covalent bond?
Carbon is important for organisms because...
What is ... explain reasons.
Hydrogen peroxide is the _____________ for catalase.
What is substrate?
Nonpolar molecules, including fats, oils and waxes, do not mix well with these types of molecules.
What are polar molecules?
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?
NaCl, C6H12O6, and H2O are all examples of these.
What are compounds?
This reaction bonds monomers together through the removal of a hydrogen ion (H+) from one monomer and a hydroxide ion (OH-) from the other. Hint: It's two words; the first is related to water.
What is dehydration synthesis?
This occurs to enzymes when environmental conditions damage their structure.
What is they are denatured?
This process is what allows plants to be able to move water from their roots in the soil all the way to the highest leaf before transpiration occurs from there.
What is capillary action?
Monomer is called a nucleotide. Nucleotides are made of phosphate group, sugar and a base. DNA and RNA are examples.
What are nucleic acids?
