protein synthesis Correct Answer: the process by which amino acids are joined together to form proteins, such as lean tissues, like muscle. What is the molecular component that makes each individual amino acid unique? Correct Answer: Side chain peptide bond Correct Answer: The bond between 2 amino acids, occurring between the carboxyl group of one and the amino group of the other. cell signaling Correct Answer: Process of communication between cells by biological messengers to govern cellular function. Hydrolysis
Correct Answer: Breakdown of one large molecule into two smaller molecules via the donation of one hydrogen and one hydroxyl group from water to the smaller molecules, respectively. dehydration synthesis Correct Answer: The joining of two large molecules by removing one hydrogen from one molecule and a hydroxyl group (-OH) from another molecule, and then binding the two larger molecules together on the newly freed bonds. amino acids Correct Answer: The organic building blocks of proteins containing both a carboxyl and an amino group. Gluconeogenesis Correct Answer: The formation of glucose from noncarbohydrate sources, such as amino acids. acid-base balance Correct Answer: the equilibrium in the body between acid and base concentrations What amino acid is essential in the human diet? Correct Answer: Leucine
What protein has a triple helix molecular structure and works with calcium to form bones? Correct Answer: Collagen RDA for protein women Correct Answer: 46 grams RDA for protein men Correct Answer: 56 grams According to the USDA My Plate, what percentage of one's diet should come from high- protein sources? Correct Answer: 20 - 25% How much daily protein is recommended for someone who participates in regular moderate-intensity resistance training? Correct Answer: 1.5-2.0 g/kgBW Performing resistance training while consuming a high protein diet consisting of 1.8-2. g/kgBW daily protein can help maintain muscle mass during a calorie-restricted weight loss diet. Correct Answer: true
Which amino acid is responsible for signaling for muscle protein synthesis, and is the only amino acid independently capable of enhancing muscle anabolism? Correct Answer: Leucine What protein timing strategy has been shown through research to be the most optimal for continued muscle protein synthesis throughout the day? Correct Answer: 4 meals with 20g protein each How do protein and amino acids influence body pH? Correct Answer: They act as buffers to maintain neutral pH. For an individual engaged in vigorous resistance training 5-6 days per week, what would be the most optimal protein prescription? Correct Answer: 2.0 g/kg body weight An existing client has been doing very well with meeting daily dietary recommendations with a three-meal per day eating pattern and they have met their goal to reach a healthy body weight with increased muscle tone. They express they would like to now pursue a new goal of a doing a physique competition within the next 12 months. Should the Nutrition Coach recommend they eat more or less frequently to help them meet their goals? Correct Answer: A Nutrition Coach should recommend they eat more-frequent meals because they can more frequently stimulate muscle growth.
How many essential amino acids are there? Correct Answer: 9 What is dehydration synthesis? Correct Answer: Removal of 2 hydrogens and 1 oxygen from 2 different molecules when the 2 molecules are joined together what is true about high-protein snacks? Correct Answer: Protein-based snacks without excess fats or carbohydrates can enhance satiety and, therefore, weight loss. What are essential amino acids? Correct Answer: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, valine What is the main protein involved in regulating fluid balance? Correct Answer: Albumin What is an ideal daily protein distribution? Correct Answer: Each meal contains an equal amount of protein. In what form are proteins primarily absorbed? Correct Answer: Single amino acids
Which of the following amino acids is essential in the human diet? Correct Answer: Leucine Which protein is one of the largest polypeptides in the body and gives muscles their property of elasticity? Correct Answer: Titin Titin Correct Answer: a protein that positions the myosin filament to maintain equal spacing between actin filaments poly Correct Answer: many, several oli Correct Answer: few or small mono Correct Answer: one, single di Correct Answer: two, double
Correct Answer: transport oxygen Functions of amino acids Correct Answer: tissue repair; immune system support; neurotransmitter support; growth; osmotic balance; pH balance Muscle anabolism Correct Answer: energy-requiring metabolic processes that build muscle tissue Which of the following is the best prescription for daily protein intake for an older, sedentary individual? Correct Answer: 1.3 g/kg body weight Which is most likely to impact longevity? Correct Answer: Calorie restriction may enhance longevity. Is post-workout protein consumption more important for novice or experienced weightlifters? Correct Answer: Experienced Protein is involved in forming which of the following? Correct Answer: bones
