Vocab 1
Atoms of the same element that have different numbers of neutrons.
What is an isotope?
The basic building block of matter.
What is an atom?
The general structure is reactant + reactant = product + product.
What is a chemical equation?
This type of force involves a hydrogen atom and a fluorine atom, oxygen atom or a nitrogen atom.
What is a hydrogen bond?
This macromolecule contains repeating CH2O units and is the central source of energy for organisms.
What are carbohydrates?
Atom that has lost or gained an electrons; carrying an electric charge.
What is an ion?
Water (H2O) and salt (NaCl) would be examples.
What is a compound?
The main role of this molecule is to lower the activation energy of a biological reaction.
What is an enzyme?
Geckos and water bugs use this type of force to climb/stay on top of water.
What is Van der Waals Forces?
These fatty macromolecules are made of mostly carbon and hydrogen; primary function is to store energy.
What are lipids?
Minimum amount of energy needed for reactants to form products in a chemical reaction.
What is activation energy?
It's location is in the nucleus and has neither a positive nor negative charge.
What is a neutron?
The protein that binds to an enzyme.
What is a substrate?
Coffee with well mixed sugar and cream is an example of this type of mixture.
What is a homogenous mixture?
These macromolecules transmit and store genetic information.
What are nucleic acids?
Molecules that have an unequal distribution of charge.
What are polar molecules?
One bond shares electrons, while the other steals electrons.
What is the difference between ionic and covalent bonds?
One reaction releases more energy than it takes in while the other takes in more energy than it releases.
What is an exothermic and endothermic reaction?
H+ ions are released when this type of substance comes into contact with water.
What are acids?
Chains of amino acids make up this macromolecule.
What are proteins?
Substance in which another substance is dissolved.
What is a solvent?
This is the most common element in both your body and in the Earth's crust.
What is oxygen?
These are factors that affect enzyme activity.
What is temperature, pH & inhibitors.
OH- ions are released when this type of substance comes into contact with water.
What are bases?
This is the last level of folding in three - dimensional protein structure.
What is quaternary structure?
