NUTRITION & HEALTH DIXON EXAM 2 RUTGERS
UPDATED ACTUAL QUESTIONS AND CORRECT
ANSWERS
Question:
Proteins
Answer:
Required for growth, want complete protein when growth occurs
Question:
Amino Acids
Answer:
Your body uses 20 of these to make proteins
Question:
High Quality Protein
Answer:
Has all essential amino acids, highly digestible, eggs and milk
Question:
Essential Amino Acids
Answer:
Amino acids that are needed, but cannot be made by the body; they must be
eaten in foods
Question:
Nonessential Amino Acids
Answer:
Amino acids that the body makes
Question:
Protein Nutrition Balance Studies
Answer:
Performed during WWII using nitrogen balance method
Question:
Babies grow in
Answer:
Spurts
Question:
Protein Synthesis
Answer:
Synthesis and Degradation are occurring at the same time, inhibits protein
breakdown
Question:
How do cells synthesize protein?
Answer:
They utilize free amino acids from the cytosol, and with the aid of ribosomes
and other factors
, Question:
What is protein synthesis not (less) dependent on?
Answer:
Hormones and other factors (diet, old age)
Question:
What happens with the amino acids after released from degraded protein?
Answer:
For the most part, re-utilized (recycled) for additional protein synthesis. In
adults this approaches 90-95% re-utilization
Question:
Protein Turnover
Answer:
Occurs in all cells at the same time as protein synthesis. More sensitive to
outside factors such as hormones than protein synthesis
Question:
How was the amount of protein needed in a day figured out?
Answer:
With nitrogen balance studies in the 1940's through 60s
Question:
Intracellular Protein Degradation
Answer:
Provides constant supply of amino acids for synthesis of important proteins
Question:
Lysosome
Answer:
Mechanism of Protein Degradation, compartment (organelle) within the cell
Question:
Ubiquitin/Proteasome System
Answer:
More sensitive to outside factors such as hormones than protein synthesis,
Nobel Prize in Chemistry-2004
Question:
Dietary Protein
Answer:
0.34g protein per kg body weight (required) 70kg man - 24.5g 60kg woman -
21g
Question:
Is extra protein needed for extreme high exercise intensity?
Answer:
No, they consume more kcal and naturally eat more protein; Arctic explorers
experiment
Question:
Soy
