Chemistry in Biology
What are atoms? - ANS - Atoms are the building blocks of matter.
\What are enzymes? - ANS - Special proteins that speed up the rate of chemical
reactions in biological processes.
\What are lipids? - ANS - Molecules made mostly of carbon and hydrogen that
make up fats, oils, and waxes.
\What are proteins? - ANS - A compound made of admin acids.
\What are the parts of a chemical equation? - ANS - Reactants and products
\What is a base? - ANS - Substances that release hydroxide ions when dissolved
in water.
\What is a carbohydrate? - ANS - Compound composed of carbon, hydrogen and
oxygen in a ratio of one oxygen and two hydrogen atoms for each carbon. Sugars
\What is a catalyst? - ANS - A substance that lowers the activation energy needed
to start a chemical reaction.
Seeds up the reaction.
\What is a chemical reaction? - ANS - The process of atoms or groups of atoms in
substances reorganizing into different substances.
\What is a coefficient? - ANS - The number written in front of a reactant or
product.
\What is a compound? - ANS - A pure substance formed when two or more
different elements combine.
\What is a covalent bond? - ANS - The chemical bond that forms when electrons
are shared.
\What is a heterogenous mixture? - ANS - A mixture where the components
remain distinct. There are chunks.
\What is a homogenous mixture? - ANS - A mixture with a uniform composition.
The same throughout.
\What is a mixture? - ANS - A combination of two or more substances in which
each substance retains its individual characteristics and properties.
\What is a nucleic acid? - ANS - These store and transmit genetic information.
\What is a radioactive isotope? - ANS - An isotope that gives off radiation.
\What is activation energy? - ANS - The minimum amount of energy needed for
reactants to form products in a chemical reaction.
\What is an acid? - ANS - Substances that release hydrogen ions when they
dissolve in water.
