Macromolecules
What are Carbohydrates good for?
Quick energy and cell structure
What is adhesion?
The binding of 2 or more cells together or 2 elements sticking together
What is the difference between Alpha-Helix and Beta-Sheet
The Alpha-Helix amino acid chain coils, while the Beta-Sheet amino acid chain folds back and forth.
What is hydrophilic?
Water-loving
What is the difference between monomers and polymers?
Mono= 1 (makes up polymers)
Poly= many (being able to bond)
What is the function of nucleic acids?
Storing and transmitting instructions to make proteins (DNA and RNA)
What process breaks a bond?
Hydrolysis (adds water to the molecule)
What is polarity?
Refers to how the electrons are not distributed evenly in the molecule.
What is an Ionic bond?
Type of primary bond formed when electrons are transferred from one atom to another
What are the nitrogen bases in DNA?
adenine, guanine, cytosine, and thymine.
What are some examples of carbohydrates?
Sugar, Starch, Fiber
What process forms a bond?
Dehydration Synthesis
What make up an amino acid?
Carboxyl group, R group, hydrogen, central carbon and amino group
What is Anti-parallel?
Describes how the 2 sides of DNA molecule are oriented in opposite directions with the other 5 & 3 end across from each other on each end
Define surface tension?
Tendency for a liquid at rest to move to the smallest amount of surface area
What elements make up protein?
Carbon, hydrogen, oxygen, nitrogen
What is cohesion?
The act, state or process of sticking together caused by intermolecular forces.
What is the Amino Terminus?
It is the start of a protein chain, where the first amino acid in the sequence has a free amino group
What describes the structural arrangement of the nitrogen bases of DNA?
What are the functions of protein?
Muscle contraction, cell transport, enzymes
What is hydrogen bonding?
When hydrogen is attracted to a strongly electronegative atom such as oxygen, fluorine or nitrogen.
What are the 4 structures of protein?
Primary, Secondary, Tertiary and Quaternary
What are the monomers of Nucleic Acids?
Nucleotides
