Chemistry
A substance that cannot be broken down to other substances by chemical reactions
What is an element?
This property of water demonstrates the attraction of one water molecule to another.
What is cohesion?
Bond created when electrons are shared
What is covalent bond?
What is the building block or monomer of proteins?
amino acids
This term is the full form of the abbreviation DNA
What is Deoxyribonucleic Acid?
Four elements that make up approximately 96% of living matter
What is Oxygen, carbon, hydrogen, nitrogen?
This property of water allows water to be attracted to other surfaces (think water in a tube)
What is adhesion?
The weakest attraction forces
What is Van der waal forces?
What type of macromolecule consists of long chains of amino acids and plays a crucial role in enzyme catalysis, structural support, and transport within cells?
proteins
This DNA base is not found in RNA and is instead replaced by Uracil.
What is Thymine?
Subatomic particles that are found in the nucleus
What are protons and neutrons?
This property is why insects can "walk" on water

What is the primary function of enzymes in biological systems?
to catalyze or speed up chemical reactions in living organisms
The process where RNA is made from DNA.
What is Transcription?
Is Magnesium a trace element?
No, it is essential element
This is why it takes more energy to increase the temperature of water compared to other substances
Overall charge of ionic compounds

What term is used to describe the specific region of an enzyme where a substrate molecule binds?
active site
These two polysaccharides are used to store carbohydrates in plants.
What are starch and cellulose?
Two atoms of an element that differ in number of neutrons.
What is an isotope?
The polarity of a substance that cannot be dissolved by water
What is non-polar?
A molecule with more of these bonds will have high melting and boiling point
What are H-bonds?
(strong intermolecular attractive forces)
what is the name of the three-nucleotide sequence on an mRNA molecule that codes for a specific amino acid?
codon
The linkage between monosaccharide’s in a polysaccharide.
What is Glycosidic linkage?
