Study These Flashcards
A

Allosteric site

24
Enzymatic pathways require control so cells may regulate enzyme activity. Control is achieved via
Feedback inhibition
25
Removal of electrons
Oxidation
26
Gain of electrons
Reduction
27
An oxidation reaction paired with a reduction reaction
Redox reaction
28
The breakdown of carbohydrates to release energy
Carbohydrate catabolism
29
Breakdown of glucose from 6 carbon to 3 carbon
Glycolysis
30
Further breakdown or glycolysis product
Krebs
31
Oxidation reduction chain to produce ATP
Electron transport chain
32
True false: fermentation goes to Krebs
False
33
True false: respiration goes to Krebs
True
34
The oxidation of glucose to pyruvic acid produces ATP and NADH
Glycolysis
35
4 ATP produced, 2 ATP used, 2 net ATP are produced, 2 NADH produced, 2 pyruvic acid
Glycolysis
36
Oxidation of molecules liberates electrons for an electron transport chain
Cellular respiration
37
ATP is generated by oxidative phosphorylation
Cellular respiration
38
Oxidation of acetyl CoA produces NADH and FADH2
Krebs cycle
39
NADH and FADH2 deliver electrons and hydrogen ions to the ETC
Electron transport chain
40
Electrons are transferred between the chain molecules by a series of oxidation reduction steps
ETC
41
This cases hydrogen ions to move across a membrane and build up a high concentration on one side
ETC
42
Hydrogen ions move down their concentration gradient through ATP synthase, which drives synthesis of ATP when O2 is available
ETC
43
ETC site in eukaryotic cell
Inner mitochondrial membrane
44
ETC site in prokaryotic cell
Plasma membrane
45
The final electron acceptor in the electron transport chain is molecular O2
Aerobic respiration
46
The final electron acceptor in ETC is not O2
Anaerobic respiration
47
Why does anaerobic respiration yield less energy than aerobic respiration?
Because only part of the Krebs cycle operates under anaerobic conditions
48
Inorganic electron acceptor | No O2 require
Anaerobic respiration
49
Energy produced from a complete oxidation of one glucose using aerobic respiration
Carbohydrate catabolism
50
Any spoilage of food by microorganisms
Fermentation
51
Any process that produced alcoholic beverages or acidic dairy products
Fermentation
52
Any large scale microbial process occurring with or without air
Fermentation
53
Releases energy from oxidation of organic molecules Does no require O2 Does not use Krebs or ETC
Fermentation.
54
Uses organic molecule as final electron acceptor
Fermentation
55
Conversion of light energy to chemical energy
Photosynthesis
56
Carbon fixation and light independent (dark) reaction
Synthesis
57
Fixing carbon into organic molecules
Synthesis
58
Calvin benson cycle
Light independent/ dark reaction
