Patterns of Life
The universal genetic code that is present in every cell.
The most basic unit of matter.
What is the atom?
The ability of water molecules to stick to each other because of their polarity.
What is cohesion?
This class of organic compounds include sugars or starches, and are used to store energy.
What are carbohydrates?
The energy needed to start a chemical reaction.
What is activation energy?
The most basic unit of life, an organism can be made up of just one or of many of them.
What is the cell?
Atoms of the same element containing different numbers of neutrons in the nucleus.
What are isotopes?
Acids and Bases measured on this scale.
What is the pH scale?
This organic compound includes fats and oils which are used for long-term energy and in the cell membrane.
What is a lipid?
Proteins that speed up chemical reactions in cells, requiring less activation energy.
What are enzymes?
The relatively constant conditions that must be maintained within an organism.
What is homeostasis?
This type of bond is formed when electrons are transferred from one atom to another.
What is an ionic bond?
An acid measures the amount of these ions.
What are hydrogen ions?
This organic macromolecule is made of monomers called amino acids.
What are proteins?
A name for reactants that bind to an enzyme in order for a reaction to occur.
What are substrates?
This concept is the foundation of science and is something you look for when analyzing data.
What are patterns?
This type of bond is formed by the sharing of electrons and can result in a polar molecule.
What is a covalent bond?
This weak acid acts as a buffer in the blood.
What is carbonic acid?
The monomers (building blocks) of nucleic acids such as DNA and RNA.
What are nucleotides?
A type of reaction that can happen spontaneously and which makes energy available for use, such as the digestion of starches into monosaccharides.
What is an energy-releasing reaction?
This concept deals with the interactions between different components within a set boundary.
What are systems and system models?
The type of weak bond that forms between polar molecules like water.
What is a hydrogen bond?
This weak base is made from carbonic acid and is part of the blood's buffering system.
What is bicarbonate?
A fatty acid that contains double-bonded carbon atoms and tends to be liquid at room temperature.
What are unsaturated fats?
The production of sugars through photosynthesis is an example of this type of reaction that stores energy in the product.
What is an energy-absorbing reaction?
