Flashcards in lecture 1.10 Deck (33):
1

Catabolism=

as in take apart

2

Anaboilsm=

as in put together

3

Describe catabolism

usable energy-producing reactions or fueling reactions
provide ready source or reducing power (electrons)
generate precursors for biosynthesis

4

Describe Anabolism

the synthesis of complex organic molecules from simpler ones
requires energy derived by fueling reactions

5

Describe the first law of thermodynamics

Energy can be neither created nor destroyed
Total energy in universe remains constant

6

Describe the second law of thermodynamics

Entropy--amount of disorder in a system
Physical and chemical processes proceed in such a way that the disorder of the universe increases

7

Calorie=

amount of heat energy needed to raise 1 gram of water from 14.5 to 15.5°C

8

Joules=

units of work capable of being done by a unit of energy

9

1 cal = ___ joules?

1 cal of heat is equivalent to 4.1840 J of work

10

if G is negative, reaction is _________

spontaneous

11

if G is positive, reaction is ___________

not spontaneous

12

if G = 0, reaction is __________

at equalibrium

13

Exergonic reaction, then G is ______

negative

14

Endergonic reactions, then G is ________

positive

15

Exergonic reactions means the reaction will _______

proceed spontaneously

16

Endergonic reactions mean the reactions will ________

not proceed spontaneously

17

What is an oxidation reaction?

Electron carriers are often used to transfer electrons from an electron donor to an electron acceptor

18

more negative E0 means

better electron donor

19

more positive E0 means

better electron acceptor

20

The greater the difference between the E0
of the donor and the E0 of the acceptor means what in terms of G?

the more negative the Go´

21

What are some examples of electron carriers?

NAD, NADP, FAD, Coenzyme Q

22

What are the two types of Chemoorganotrophic energy supply?

Respiration
Fermentation

23

What are the two types of respiration and their differences?

aerobic: terminal electron acceptor is O2
anaerobic: some other terminal electron acceptor

24

What has no exogenous electron acceptor?

Fermentation

25

How does respiration primarily make ATP?

PMF or proton motive force

26

What is the main difference in regards to making energy for aerobic and anaerobic?

Anaerobic does not use the Electron Transport Chain (ETC)

27

Amohibolic Pathway=

Function both as catabolic and anabolic pathways

28

What is important about the Embden-Meterhof Pathway (EMP)

There is a net of two ATP and 2 NADH

29

What is the summary of Glycolysis?

glucose + 2ADP + 2Pi + 2NAD+

2 pyruvate + 2ATP + 2NADH + 2H+

30

What is important about the Enter-Duodoroff Pathway? (EDP)

Yeilds 1 ATP, 1NADPH, 1NADH

31

What are examples of the amphilbolic pathways?

Embden- Meterhof, Enter-Duodoroff, Pentose Phosphate

32

What is important about the Pentose Phosphate System

2 NADPH and two of 12 major precurosrs

33

What is important about the Tricarboxylic Acid Cycle? (TAC)

Two molecules of CO2, 2 NADH, 1 FADH, 1 GTP, Several of the big 12 precursor molecules
