lecture 9 Flashcards
when you eat too much carbohydrates
a. You produce more ATP’s
b. You store some as glycogen
c. You convert all of it into fat
d. You can turn extra glucose into amino acids
store some as glycogen
some excess glucose can be turned to glycogen, limit storage is :
a. About 2 lb
b. About 8 lb
c. About 10 lb
d. No limit
About 2lb
After glycogen stores are built to their maximum, excess glucose is converted into :
a. ATP’s
b. Lactic acid
c. Fats
d. Protein
Fats
Excess dietary fat is :
a. turned into glucose
b. turned into glycogen
c. turned into protein
d. stored as is
stored as is
Tissue cells can do the following with excess amino acids, except :
-store for later
-turn them into glucose
-turn them into fat
-use them as fuel
store for later
The primary purpose of dietary protein is :
to provide amino acids as building blocks for making new proteins
when amino acids are used for purposes other than building proteins the following are true except :
-amino acids get deaminated and turned into ketoacids
-ketoacids are excreted as a metabolic waste
-deamination yields ammonia
-ammonia is turned into urea by the liver
-urea is excreted via kidneys
ketoacids are excreted as a metabolic waste
which of the following does not happen during nutrient deprivation
-cortisol levels increase
-leptin levels increase
-glucogen stores are broken down
-fat stores are broken down
-muscle protein is broken down
leptin levels increase
In the first 5-7 days of a very low calorie diet, it is typical to lose about 10 lb of
weight. What is the composition of the weight loss?
a. It’s all water
b. It’s mostly protein and water
c. It’s mostly glycogen and water
d. It’s mostly fat and glycogen
e. It’s mostly fat and protein
its mostly glycogen and water
The state of ketosis indicates that :
a. Glycogen stores are depleted
b. Fat stores are being broken down
c. Fat is turned into ketones
d. All of the above
all of the above
Tissue that cannot use ketones as the sole source of energy and must use
a. Skeletal muscles
b. Myocardium
c. Brain
d. Connective tissue
brain
When carbohydrates are unavailable, and glycogen stores are depleted, this is
used as the source of glucose:
a. Fats
b. Ketones
c. Muscle protein
d. Liver
Muscle Protein
After the dieting period is over, the following is true, except:
a. The body has become dehydrated
b. The body is depleted of glycogen stores
c. The body has lost some muscle tissue
d. The body has lost some fat tissue
e. The body has become leaner
The body has become leaner
Which of the following is NOT true about the Atkin’s diet?
a. It is a ketogenic diet
b. It is a dehydrating diet
c. It is a very low-carb diet, which is a good solution for diabetic patients
d. It puts an excess strain on kidneys
It is a very low-carb diet, which is a good solution for diabetic patients
Which of the following is true about Ornish diet?
a. It was designed for cardiac rehab patients
b. It is a very low-fat diet
c. It tends to be high in carbohydrates, leading to hypoglycemic crashes
shortly after meals
d. It may cause cells to turn excess glucose into fat
e. All of the above are true
All of the above are true
