1

anabolic reactions

require energy

2

catabolic rxn

release energy

3

substrate-level phosphorylation

the formation of ATP (or GDP to GTP)by transferring a phosphate group from an high-energy metabolic intermediate.

4

oxidative phosphorylation

the formation of ATP by transfer of electrons from reduced coenzymes to molecular oxygen via the electron transport chain; it occurs in the mitochondria.

5

Where is FADH2 made?

Kreb cycle only. 2 total.

6

Kreb Cycle makes ATP by

still substrate level phospho.

7

aerobic pathway

involves the mitochondria

8

why is pyruvate moved to mitochondria

active trasnport using 2 ATP, 1 for each pyruvate

9

inner membrane versus intermembrane space

inner membrane is cristae, the phospholipid bilayer. intermembrane space is the space between outer membrane and cristae where H+ gradient is made.

10

products of pyruvate decarboxylation

2 CO2, 2acetyle CoA, 2 NADH

11

first CO2 is released where?

mitochondria

12

what enters Kreb Cycle

acetyl-CoA

13

acetyl-CoA+ X =Y

X= oxalocaetate 4 carbon
Y= citric acid 6 carbon molecule

14

what allows reduction of NAD+ and FAD to NADH and FADH2?

reaarangement of intermediates in the Kreb cycle

15

what happened to glucose at the end of the kreb cycle

fully oxidized into CO2

16

how many grand total ATP made during cellular respiration of glucose

36

17

2 problems of no O2

no ETC, NADH can't be oxidized to NAD+ and reused for glycolysis

18

does fermentation produce ATP

No. remember fermentation and those are ways of recycling NADH, not a means of producing ATP
