Chapter 2.5 Organic Molecules Flashcards
………..provide structural support and act as catalysts that facilitate chemical reactions
Proteins
……………encode and transmit genetic information
Nucleic acid
…………….provide a source of energy and make up the cell wall in bacteria, plants and algae
Carbohydrates
…………make up cell membranes, store energy, and act as signaling molecules
Lipids
The monomers of proteins are
Amino acids
The monomers of Nucleic acids are
Nucleotides
The monomers of carbohydrates are
Sugars
Lipids do not have monomers as they are defined by…..rather than by their chemical structure
Property
Groups of one or more atoms that have particular chemical properties of their own, regardless of what they are attached to are called
Functional groups
An amino acid contains a central carbon atom called…….. which is covalently links to four other groups. Name them
Alpha carbon
Amino group
Carboxyl group
R group
Hydrogen atom
The carbon atom in the carboxyl group of one amino acid is joined to the nitrogen atom in the amino group of the next by a covalent linkage called
Peptide bond
The formation of peptide bin involves the ……..of a water molecule
Loss
The particular sequence, or order in which amino acids are present in a protein determines ……
How it folds into its three dimensional structure
The three dimensional structure of a protein determines …..
The protein’s function
What is the function of the DNA
It contains the information needed to specify the amino acid sequence of all the proteins synthesized in an organism
