New cards
What food gives us
energy
2
New cards
energy is not
recycled
3
New cards
Photosynthesis converts light into
chemical energy
4
New cards
what does cellular respiration break down into energy
glucose
5
New cards
some energy is lost through
heat
6
New cards
waste products of respiration
water and carbon dioxide
7
New cards
All living things perform
respiration
8
New cards
The energy in glucose from glucose is used to make
ATP
9
New cards
Anaerobic
does not require oxygen
10
New cards
aerobic
does require oxygen
11
New cards
the first stage of respiration
glycolysis
12
New cards
Does glycolysis require air
no
13
New cards
Second stage of respiration
krebs cycle
14
New cards
third cycle of respiration
Electron transport chain
15
New cards
glycolysis occurs in the
cytoplasm
16
New cards
How much ATP does glycolysis have a gain of
two
17
New cards
NADH job
electron acceptor; carries electrons to the ETC
18
New cards
why can’t people only do glycolysis
The product is only 2 ATP and not enough to sustain human life
19
New cards
What happens to pyruvic acid
If oxygen is present, it undergoes aerobic respiration. If oxygen is not present, it undergoes fermentation.
20
New cards
How much additional ATP does fermentation produce
None
21
New cards
where does fermentation occur
cytoplasm
22
New cards
two major stages of aerobic respiration
Krebs cycle and electron transport chain
23
New cards
Most of the ATP produced in aerobic respiration was produced by the
electron transport chain
24
New cards
In prokaryotic cells, where does the Krebs cycle and ETC take place
cytoplasm and special structures of the cell membrane
25
New cards
structures of the mitochondria
the outer membrane, inner membrane, matrix, cristae
26
New cards
where is the matrix located
inside the inner membrane
27
New cards
cristae
folds and loops inside the mitochondria; increase surface area for the reaction of respiration
28
New cards
Krebs cycle occurs in what part of the mitochondria
matrix
29
New cards
ETC occurs in what part of the mitochondria
cristae membrane
30
New cards
bridge reaction
the bridge between cytoplasm and mitochondria, anaerobic and aerobic respiration, and glycolysis and Krebs cycle
31
New cards
NAD and FAD
electron carriers in the Krebs cycle
32
New cards
one turn of the Krebs cycle produces
2 CO2; 1 ATP; 3 NADH; 1 FADH2
33
New cards
Electron transport chain is
a series of four protein complexes, creating ATP in a complete system named oxidative phosphorylation.
34
New cards
the majority of the energy contained in glucose is given off as
heat
35
New cards
two types of fermentation
alcoholic and lactic acid
36
