1

anabolism =

synthesis of larger molecules from smaller molecules
requires energy
endergonic

2

catabolism

breakdown of larger molecules into smaller molecules
releases energy
exergonic

3

Energy is gained form, and stored in this form

ATP
Adenosine triphospate

4

Two types of cellular respiration

anaerobic respiration (does not require oxygen)
aerobic respiration (requires oxygen)

5

Another word for anaerobic respiration

glycolysis

6

T/F: aerobic respiration is considered the primitive type of respiration

F, anaerobic

7

Formula for glycolysis

glucose -> 2 pyruvic acid + electron carriers

8

In aerobic respiration pyruvic acid is converted into (full pathway)

acetyl CoA -> citric acid + electron carriers

9

Citric acid enters into this cycle

krebs cycle

10

All electron carriers enter this chain

electron transport chain

11

This combines with acetyl CoA to from this in the krebs cycle

Oxaloacetic acid
citric acid

12

These are formed during the krebs cycle (energy)

3 NADH
1 ATP
1 FADH2

13

In the electron transport chain these are pumped into this space

hydrogen ions
intermembrane space

14

This is needed to activate the hydrogen pumps

electron carriers

15

These are imbedded in the inner membrane of the mitochondria and assist in the electron transport chain

enzyme systems

16

As electrons move from one enzyme system to the next this occurs

hydrogen ions are pumped into the intermembrane space

17

These two things are used to produce ATP in the electron transport chain

High H+ concentration
ATP Synthase (ADP + Pi = ATP)

18

This much ATP is produced through aerobic respiration

30

19

This many ATP are produce by the krebs cycle and glycolysis

4

20

This many ATP are produce by the electron transport chain

26

21

Acetyl CoA can be converted into this four things

Citric acid (krebs cycle)
fatty acids
ketone bodies
cholesterol

22

Energy source preference: brain

glucose

23

Energy source preference: skeletal muscles (resting)

Fatty acids

24

Energy source preference: liver

fatty acids

25

Energy source preference: Heart

fatty acids

26

Insulin facilitates this

uptake of glucose into cells from the blood

27

Insulin increase does this

reduces blood sugar levels
increases uptake of glucose into cells

28

Two types of cells in the pancreatic islets

alpha cells
beta cells

29

Beta cells produce this

insulin

30

alpha cells produce this

glucagon
