-
proteins are found as parts of blank blank, blank blank, and blank
muscle tissues, cell membranes, enzymes
-
Proteins are long chains of blank blank
amino acids
-
The end of an amino acid with a nitrogen atom is the blank group and the end with a carbon atom with two oxygen atoms and a hydrogen atom is the blank group
amino, carboxyl
-
the -COOH on the end is an blank
acid
-
Amino acids are different at the blank attached to the central carbon atom
atom
-
the smallest amino acid is blank that has a blank attached to its central carbon
glycine, hydrogen
-
a blank bond unites two amino acids
peptide
-
two amino acids attached to each other form a blank
dipeptide
-
the sequence of amino acids in a long chain is called a blank chain
polypeptide
-
the primary structure of a protein is the
long chain of amino acids/ polypeptide
-
the secondary structure of a protein is the blank
coiling of the polypeptide into a spiral helix
-
the tertiary structure of a protein is blank
spiral helix or sheet folding upon itself
-
the quaternary structure of a protein is blank
more than one polypeptide chain linked together
-
proteins that act as catalysts, causing chemical reactions in cells to proceed faster are blank
enzymes
-
the molecules that are changed in these chemical reactions are called blank molecules
substrate
-
blank and blank are nucleic acids
RNA, DNA
-
nucleic acids serve as the blank and blank within the cells
blueprints, managers
-
Amino acids are the building blocks of proteins, and blank are the building blocks of nucleic acids
nucleotides
-
each building block of a nucleic acid is composed of a blank blank molecule, a blank molecule, and an blank
5-carbon, sugar, phosphate, organic base
-
DNA stands for blank
deoxyribonucleic acid
-
RNA stands for blank
ribonucleic acid
-
the backbone of a nucleic acid is an alternating sequence of blank and blank
sugar, phosphate
-
in DNA, the sugar is called blank because an oxygen atom is absent on the lower right carbon atom
deoxyribose
-
in RNA, the sugar is called blank because on oxygen atom is present on the lower carbon atom
ribose
-
DNA and RNA both have the bases blank, blank, and blank
adenine, guanine, crytosine
-
only DNA has the base blank
thymine
-
only RNA has the base blank
uracil
-
a DNA molecule has blank strands of nucleotides
two
-
the opposing strands of a DNA molecule form a staircase stucture called a blank
helix
-
a RNA molecule has blank strand of nucleotides
one
-
in DNA, the base blank is always opposite the base thymine
adenine
-
in DNA, the base blank is always opposite the base cytosine
guanine
-
the DNA strands are held together by blank bonds
hydrogen
-
blank (adenosine triphosphate) is a nucleotide used to store energy in cells
ATP
-
the nucleotide in question 34 loses a blank when it releases energy and becomes blank (adenosine diphosphate)
phosphate molecule, ADP
