Atoms and Bonding
A substance that cannot be broken down further into simpler matter.
What is an element?
This element has an atomic number of 15.
What is phosphorus?
Acidity is measured on this scale.
What is the pH scale?
Most enzymes end in this suffix.
What is "ase"?
This is the reaction that generates heat/light energy that is expelled toward the external environment.
What is exothermic reaction?
Subatomic particle with a positive charge.
What is a proton?
This element has 11 protons.
What is Sodium or Na?
Type of ions produced by bases
What is hydroxides? OH-
The type of chemical reaction where enzymes help to break apart molecules.
What is a catabolic reaction?
This reaction absorbs heat energy but requires high amount of activation energy.
What is endothermic reaction?
A bond which forms when electrons are transferred.
What is an ionic bond?
Atoms of the same type which have the same number of protons but differing numbers of neutrons.
What are isotopes?
The reactants in a chemical reaction are called this as they interact with an enzyme.
What is a substrate?
In terms of energy, the type of reaction where the products have less energy than the reactants.
What is an exothermic reaction?
A weak bond which forms between water molecules resulting in cohesion.
What is a hydrogen bond?
Carbon-14 has how many protons and how many neutrons.
What is 6 protons and 8 neutrons?
The fancy science word which indicates that an enzyme is no longer functional (died).
What is denatured?
In terms of energy, the type of reaction where products have more energy that the reactants?
What is an endothermic reaction?
Chemical bond in which electrons are shared.
What is a covalent bond?
Unstable atoms can release this type of energy if their number of neutrons are higher than their number or protons.
What is radioactivity?
pH is a log based 10 mathematical calculation. How many times stronger is an acid with a pH of 2 than an acid with a pH of 4?
What is 100 times?
This is the site where enzyme combines with substrate to form enzyme-substrate complex.
What is active site?
This is a biological substance that can lower the activation energy in a chemical reaction.
What is an enzyme?
