#1
Front (Question)

Essential amino acids

Back (Answer)

cannot be made by the body but essential that they are gotten

#2
Front (Question)

nonessential amino acids

Back (Answer)

can be made by the body

#3
Front (Question)

peptide bond

Back (Answer)

bonds amino acids

#4
Front (Question)

dehydration synthesis

Back (Answer)

1 amino + 1 amino = peptide bond

#5
Front (Question)

hydrolysis

Back (Answer)

peptide bond = amino, amino

#6
Front (Question)

what are proteins made of

Back (Answer)

amino acids

#7
Front (Question)

what are the 3 attachment groups of amino acids

Back (Answer)

• amino group • acidic carboxyl group • side chain/r group

#8
Front (Question)

what is special about the side chain of amino acids

Back (Answer)

the r group is the only thing that makes each amino acid unique

#9
Front (Question)

What happens to digested proteins

Back (Answer)

they are broken down into amino acids and NOT STORED - instead they ate either oxidized to produce ATP or used to synthesize other proteins

#10
Front (Question)

What are the main functions of proteins

Back (Answer)

• enzymes • transportation (lipoproteins) • antibodies • clotting blood • hormones • muscle fibers

#11
Front (Question)

Protein CATABOLISM

Back (Answer)

• break down • aerobic • amino acids converted into other amino acids, ketone bodies or glucose

#12
Front (Question)

Protein ANABOLISM

Back (Answer)

• protein synthesis • create new proteins by bonding together amino acids on RIBOSOMES • only occurs when they is an EXCESS of proteins

#13
Front (Question)

Protein organization

Back (Answer)

• primary structure • secondary structure • tertiary structure • quaternary

#14
Front (Question)

primary structure

Back (Answer)

amino acid sequence

#15
Front (Question)

secondary structure

Back (Answer)

twisting and folding of amino acids stabilized by hydrogen bonds

#16
Front (Question)

tertiary structure

Back (Answer)

3d shape of a polypeptide chain

#17
Front (Question)

quarternary structure

Back (Answer)

arrangement of 2 or more polypeptide chains

#18
Front (Question)

where do amino acids enter the krebs cycle

Back (Answer)

anywhere

#19
Front (Question)

What two words describe nitrogen elimination

Back (Answer)

transamination and deamination

#20
Front (Question)

Transamination

Back (Answer)

transfer amine group

#21
Front (Question)

deamination

Back (Answer)

• aka oxidative deamination (needs oxygen) removal of amine group

#22
Front (Question)

What leaves through the kidney and urine and is used to measure nitrogen levels at the end of nitrogen elimination?

Back (Answer)

UREA

#23
Front (Question)

Characteristics of Glucose - Alanine Cycle

Back (Answer)

• slow • alanine is the gluconeogenic precursor

#24
Front (Question)

amino acid -> protein =

Back (Answer)

ANABOLIC
