1

What form(s) of metabolism occur(s) in the cytosol?

Glycolysis

Pentose phosphate pathway

Fatty acid synthesis

2

What form(s) of metabolism occur(s) in the mitochondrial matrix?

TCA

Oxidative phosphorylation

ß-oxidation of FAs

Ketone body formation

3

What form(s) of metabolism occur(s) in the interplay between both cytosol and mitochondrial matrix:

Gluconeogenesis

Urea synthesis

4

7 forms of metabolism:

Glycolysis
Gluconeogenesis
Glycogen metabolism
FA metabolism
Citric acid cycle
Oxidative phosphorylation
AA metabolism

5

What organ can carry out all of the reactions in the major pathways?

Liver

6

3 key points in metabolism:

Glucose-6-phosphate

Pyruvate

Acetyl-CoA

7

3 major elements of energy in body/foodstuff?

Sugars, proteins, lipids

8

What dictates insulin/glucagon response or BG detection?

Liver

9

Central component to all of metabolism

Carbon

10

Carbohydrates and protein are both 4 kcal/g. So, if you eat the same amount, there is no difference in energy consumed, right?

No, there is a difference because of the different pathways the food req's for breakdown..different amt's of energy are required to break down either

11

In what form does the body provide energy for the metabolism [breaking down] and catabolism [forming] of biomolecules?

In the form of ATP

12

Biomolecules built from AA's

Critically important in cell life

Proteins

13

3 functions of proteins:

Fuel supply[TCA cycle->ATP production]

Structural support [elastin,keratin]

Activity[enzymes]

14

Where can several AA's be found in metabolism

As intermediates

15

Nitrogen-containing carboxylic acids

Proteinogenic AAs Serve as basic building blocks of peptides and proteins

AA function as precursors of biologically important molecules:
-acetyl CoA, heme, melanin, amines, hormones(insulin/glucagon)

Amino acids

16

What kind of amino acids are required for maintaining health?

Essential AA's

17

What is an effect of not consuming enough essential AA's?

Negative nitrogen balance

18

Organic molecules

Made up of C,H,O (3-9C[H2O])

Important fuel stores

Critical molecules control of human metabolism- catabolic

Carbon skeletons used for synthesis of the other important biomolecules-anabolic

Carbohydrates

19

4 common dietary carbohydrates:

Starch
Sucrose
Dietary fiber
Lactose

20

The nutritional reservoir in CH of plants

Polysaccharide of glucose

Amylose and amylopectin

Starch

21

The unbranched glucose polysaccharide in plants

Amylose

22

The branched glucose polysaccharide in plants

Amylopectin

23

The natural sweetener and found in fruits and vegetables

Disaccharide of glucose and fructose

Sucrose

24

Plant origin carbohydrate

Dietary fiber

25

The major dietary carbohydrates of animal origin

Disaccharide of glucose and galactose

Lactose

26

This condition is d.t the body's inability to easily digest lactose [gas,belly pain, bloating]

Lactose intolerance

27

Simplest form of carbohydrates?

Monosaccharides

28

Ex of monosaccharide:

Glucose, fructose, galactose, ribose

29

Two monosaccharides:

Disaccharide

30

Ex of disaccharides:

Maltose, lactose, sucrose
