Quiz 4

• Protein are first broken down into POLYPEPTIDES in the stomach followed by further breakdown into AMINO ACIDS
• True or false. A NEGATIVE protein, balance, often develops in individuals with an adequate protein, intake, individuals with certain diseases, and or individuals with serious illnesses or injuries.

  TRUE
• Primary structure

  Bonding of the amino acids in the polypeptide chain
• Secondary structure

  Spiral, pleated sheet shape of folded chains
• Tertiary structure


  Determines the proteins overall shape and function
• Quaternary structure

  Hemoglobin is an example of this structure
• True or false. The required chemical bond to link TOGETHER amino acids and form proteins is called a peptide bond.

  TRUE
• What is not a function of protein?

  Providing compact energy storage
• What are functions of protein?

  Providing body structures

  Acting as buffers to maintain acid base balance

  Acting as antibodies to avoid immune incompetence

  Forming glucose
• Regular beer

  12 fluid ounces
• Malt liquor

  8-9 fluid ounces
• Table wine

  5 fluid ounces
• Spirits (hard liquor)

  1.5-2 fluid ounces
• True or false. Alcohol requires BOTH digestion and absorption by the GI tract

  False
• This metabolic pathway is responsible for metabolizing about 90% of alcohol in both the stomach and liver

  ADH
• True or false. Bench drinking is defined as having more than six standard drinks for females, and seven standard drinks for a male on a single occasion.

  False
• True or false. Moderate alcohol use may be helpful to elderly individuals because it can simulate appetite and increase dietary intake

  True
• The first stage of alcoholic liver disease is

  Steatosis
• Amino acids

  Serve as a building block for protein synthesis
• Urea


  Nitrogenous waste product of protein metabolism
• Essential amino acids


  Required by diet as the body does not synthesize them
• Limiting amino acids


  Essential amino acid in lowest concentration in a food or diet relative to body needs
• High biological value (BV) 


  A food like egg white will have this because the AA pattern closely matched the AA pattern of body protein
