Question

QUESTION 32

1. If we compare a hamburger patty made from 80% lean meat versus 95% lean meat, which of the following is true?

   		There is less protein in the 95% lean meat.
   		The amount of protein is the same, but the 80% lean meat is lower in saturated fat and cholesterol.
   		The amount of protein is the same, but the 95% lean meat is lower in saturated fat and cholesterol.
   		There is less protein in the 80% lean meat.

QUESTION 33

1. There are over 100,000 different proteins produced from a combination of ____________ amino acids.

   		20
   		250
   		225
   		an unknown number of
   		100

QUESTION 34

1. Currently, the RDA for protein is the same for adults and elderly persons. Why might this change?

   		The elderly population needs fewer calories and therefore less protein.
   		When we reach a certain age protein in the diet only turns to body fat.
   		Elderly adults tend to get less exercise and therefore likely need less protein that other adults.
   		As we age, muscle mass declines so the elderly might need more protein than other adults.

QUESTION 35

1. There is some evidence that a diet too high in protein might contribute to bone loss because amino acids in the blood promote _________________ loss from bone.

   		hydrogen
   		potassium
   		calcium
   		nitrogen
   		iron

Answer 1

32)option D -There is less protein in the 80% lean meat.

80% lean meat contain 80% lean(protein) and 20% fat

95% lean meat contain 95% lean (protein) and 5% fat.

33)Option A - 20

There are 20 different type of aminoacid in our body .it is used to synthesize different protein by linking the aminoacid with polypeptide chain.

34)option A - The elderly population needs fewer calories and therefore less protein

Actually Elderly people requires less amount of protein compared to adult because the body metabolic rate will decrease with aging.

elder people bodys activity is less,so less calorie intake is needed. so the total reqquirement of protein is less.

35)Calcium

Aminoacid can cause bone weakness indirectly.

aminoacid can result in the increase of acidity of the body,inorder to compensate it the body reasorb calcium from the bine and small intestine. it result in the bne weakness
