Metabolism

Question 1

Enden Myerhoff (EM) pathway is similar to

Answer 1

Glycolysis

Question 2

main difference between EM and Edmund Deuteroph (ED) Pathway

Answer 2

1. Amnt of ATP (EM produces more ATP)

2. EM generates NADPH

Question 3

conditions nec. for EM and ED pathway

Answer 3

can be both aerobic and anaerobic

Question 4

Pentose Phosphate pathway yield:

Answer 4

intermediates that can be used for nucleotides, vitamins

takes 6-C sugar to make many different type of sugars

CO2 is released, NADPH

anaerobic or aerobic

Question 5

TCA

Answer 5

used in aerobic or aerobic if uses ETC w/different E- acceptor

needs respiration

Question 6

if pyruvate doesn’t go thru TCA, where does it go?

Answer 6

TCA cycle

Question 7

fermentation- does it occur in presence of O2?

Answer 7

NO

Question 8

how is ATP produced for fermentation?

Answer 8

thru EM pathway (substrate level phosphorylation of ATP)

Question 9

Strict fermentor

Answer 9

only complete fermentation

only get ATP from glycolytic pathway

Question 10

facultative anaerobe

Answer 10

can do respiration or fermentation

presence or absence of O2

Question 11

Goal of fermentation:

Answer 11

oxidize NADH to NAD (allows to keep making ATP from glycolysis)
