Proteins are built from simpler organic compounds called:Amino AcidsThe element nitrogen can be found only in:ProteinThe chemical structure that forms the base component of an amino acid is the:Amino GroupThe simplest amino acid is:GlycineThe number of different amino acids that make up human proteins is:20The number of amino acids that are considered indispensable or essential is:9Two amino acids are chemically joined by a:Peptide bondAmino acids that can be synthesized by the body in sufficient amounts are know as:DispensableAn important characteristic of amino acids is that they can:act as buffersAn example of a protein is:HemoglobinAn example of a tissue protein is:antibodiesA protein that contains all the essential amino acids in the proper proportion is called:CompleteAn animal protein that has negligible value as a dietary protein source when eaten alone is:GelatinProteins from plant sources such as grains, nuts, and legumes are classified as:IncompleteAn example of a complete protein is:MilkThe most significant measure of the protein quality of diet depends on the:Variety of foods consumedInfections are common in people who have inadequate protein intake because of an insufficient quantity of"AntibodiesThe nutrient that has a protein-sparing effect is:CarbohydrateThe amino acids methionine and tryptophan play a role in:Forming neurotransmittersAn example of someone who is vulnerable to health claims for amino acid supplements is:A 20-year-old male who wants to build muscleProteins are absorbed primarily in the form of:Amino AcidsPepsinogen secreted by the gastric cells is converted into pepsin by:Hydrochloric AcidThe gastric enzymes present in infants that coagulates milk is:RenninThe enzyme trypsin is activated by:EnterokinaseWhich of the following enzymes is found in pancreatic secretions:ChymotrypsinTrypsin and chymotrypsin are secreted by the:PancreasAminopeptidase and dipeptidase are secreted by the:Small intestinesAmino acids:Are water solubleAmino acids are absorbed by:Active TransportA nursing infant receives antibodies from its mother through:Absorption of antibodiesThe name of the state of dynamic equilibrium in which there is a constant ebb and flow of materials within the body is:HomeostasisA constant turnover of protein occurs between:Tissue and plasmaThe tissue that has the highest rate of protein turnover is the:Intestinal MucosaThe phase of metabolism that makes growth and repair possible is:AnabolismA negative nitrogen balance occurs in:An older adult with anorexiaAmmonia and urea are waste products from the metabolism of:amino acidsIt the excretion of nitrogen exceeds the nitrogen intake, the condition is called:Negative nitrogen balanceA period of the life cycle during which positive nitrogen balance is most likely to occur is:ChildhoodProtein catabolism is increased in health problems such as:Burn injuryThe recommended dietary intake of protein for adults is:0.8 g/kgOne of the potential consequences of eating an excess amount of dietary protein is to:Impair kidney functionThe type of food that provides the most frequent source of dietary protein for Americans is:MeatsThe greatest proportion of dispensable amino acids is provided by:EggsThe chemical score of a protein is:The ratio of indispensable amino acids in a food versus a high-quality protein reference foodWhen analyzing the amino acid composition of foods, the amino acid occurring in the smallest amount is classified as:LimitingA good reason that people choose to follow a vegetarian diet is:Health factorsA vegetarian diet in which dairy foods and eggs are included is know as:;LactoovovegetarianT or F: There are enzymes for protein digestion in the mouth:False, there are none.What elements start the breakdown of protein in the stomach:HCL Hydrochloric acid, Pepsinogen and RenninWhat does HCL do to the protein in the stomach:Denatures the protein. Unfolds the structure so enzymes can work on the proteinWhat purpose does rennin serve in the breakdown of protein:Digestion; Coagulates the milk protein for infants
No, mutations do not all result in negative effects. Sometimes they can be beneficial, as they are completely random. It is our general tendency to think of the word "mutation" in negative terms; however, do not get confused. Mutations are the root/ultimate source of genetic variation; they are one of the main factors that allow populations to evolve.
All living organisms share several key characteristics or functions: order, sensitivity or response to the environment, reproduction, growth and development, regulation, homeostasis, and energy processing. When viewed together, these characteristics serve to define life.
