Chem Rxns
In the chem rxn, these are the reactants:
2H2 + O2 --> 2H20
What is
2H2 + O2
Enzymes are this type of macromolecule
What are
proteins
Sugars are also known as this
What are
Carbohydrates
What is
cohesion
Enzymes end in this spelling
What is
-ase
In the chem rxn, these are the products:
2H2 + O2 --> 2H20
What is
2H2O
A substance that speeds up the rate of a chem rxn
What is a
catalyst
Milk has this type of sugar
What is
Lactose
This is a mixture where the solute is completely dissolved in the solvent
What is a
solution
DNA polymerase builds this molecule
What is
DNA
This is the energy needed to start a chemical reaction
What is
Activation Energy
The thing that binds to the enzyme is called this
What is a
substrate
This is the main function of lipids
What is
energy storage
The pH scale measure the concentration of this ion.
What is
H+ ions
These are 2 types of bonds that hold the atoms within a compound together
What are
covalent and ionic bonds.
What is
bonds breaking and forming
We compare the enzyme-substrate complex to this model
What is a
Lock and Key
This is the monomer of nucleic acids
What are
nucleotides
The acid of hydrogen fluoride (HF) can be dissolved in water. The pH will be this.
What is
acidic
This is a weak acid or base that helps neutralize pH
What is a
buffer
Reactions that release energy
What is
Exothermic
Enzymes work by doing this...
What is
lowering the activation energy
This is why proteins are considered polymers but lipids are not
What is because
proteins are made of monomers called amino acids
Lipids are not made of monomers-- they have not repeating units
This means that a molecule is "polar"
What is
unevenly distributed charges
What are
pH, temperature, and order of amino acids
