Flashcards in Metabolism Deck (31):
1

Utilizing compounds for the generation of energy

Catabolism

2

Utilization of energy to produce compounds

Anabolism

3

What is a major intermediate in several pathways of energy production?

Acetylene-CoA

4

Pentose Phosphate Pathway

Generates NADPH,
Generates 5 carbon sugars for nucleotides

5

Glycolysis

Glucose to pyruvate, important side products in some tissues (Glycerol-3-phosphate, 2,3-bisphosphoglycerate)

6

Gluconeogenisis

Synthesis of glucose from pyruvate (non-carb sources).
Restricted to the liver/kidney

7

Source from carbs in glycoproteins and ptoteoglycans

Glucose

8

Source of glucuronides

Glucose (very active in the liver). Makes poorly soluble compounds more soluble in aqueous environment, thus more easily extracted. Active on bilirubin and drug substrates.

9

What is Acetyl-CoA a substrate for?

TCA cycle, Lipogenesis, Cholesterol synthesis, Ketone bodies

10

What are the two end fates for amino acids?

Elimination as urea, reutilization to form another amino acid

11

What is the main source of nitrogen for the body?

Amino Acids

12

Where does gluconeogenesis occur?

Kidneys/Liver

13

What type of metabolism can RBCs not utilize?

Aerobic carbohydrate metabolism

14

In what areas of the body is glycogen mainly found?

Muscle and liver

15

In what areas of the body are triglycerides mainly found?

Adipose tissue

16

What macros do phospholipids require?

Lipids, carbs, amino acids

17

What macros do nucleotides require?

Carbs, amino acids

18

Where does fatty acid oxidation occur?

Inside the mitochondria

19

Where does fatty acid synthesis occur?

Inside the cytosol

20

How many essential carbs are there?

None

21

What type of fiber increases stool bulk and decreases transit time?

Cellulose and hemicellulose

22

What type of fiber Increases stool bulk and binds cholesterol/carcinogens?

Ligins

23

What types of fiber decrease the rate of gastric emptying/carb absorption/serum cholesterol?

Pectin and gums

24

What is the "recommended" daily protein intake?

0.8 g/kg

25

Which amino acid is considered essential for children?

Arginine

26

When would an individuals have a positive nitrogen balance?

Growth, convalescence

27

When would an individuals have a negative nitrogen balance?

Starvation, diseases, severe burns

28

2 Essential fatty acids

Linoleic acid (_6) and LinoleNic acid (_3)

29

Fats aid in absorbtion of what?

fat soluble vitamins

30

Marasmus

Extreme emanciation from prolonged negative energy balance. Loss of protein from muscle/liver/heart/kidneys

31

Kwashiorkor

Diet with adequate calories but inadequate protein.
