Cellular Respiration Flashcards
The purpose of cellular respiration is to:
Break down glucose(carbohydrates) to provide energy for the cell
Which process in cellular respiration produces the most ATP per glucose molecule consumed?
Electron transport chain/ chemiosmosis
The NET result of glycolysis is…
2 ATP and 2 NADH
In Krebs cycle, how many ATP are produced?
2
The process by which glucose is split into pyruvate.
Glycolysis
The process by which a hydrogen gradient is used to create ATP.
Chemiosmosis
A process that makes a small amount of ATP and produces lactic acid
Lactic acid fermentation
A series of membrane embedded electron carriers that ultimately create the hydrogen ion gradient to drive the synthesis of ATP
Electron transport chain
The process by which the breakdown of glucose is completed and CO2 is produced
Krebs cycle
The process that does not occur in the mitochondria
Glycolysis
Also known as citric acid cycle
Krebs cycle
Starts with Acetyl-CoA
Krebs cycle
For each molecule of glucose broken down, the Krebs cycle must make how many complete turns?
2
Two products of aerobic cellular respiration.
H2O and CO2
Anaerobic cellular respiration in humans products
Lactic acid
Anaerobic cellular respiration products in yeast and plant cells
Alcoholic fermentation (CO2 and ethanol)
Oxidation
Loss of electrons
Reduction
Gain of electrons
Where does glycolysis take place?
Cytoplasm
Products of glycolysis:
NET: 2 ATP and 2 pyruvate
Where does link reaction occur
Matrix
Waste product of link reaction
CO2
Is link reaction aerobic or anaerobic?
Aerobic
What is the product of link reaction?
2 carbons(acetal CoA which goes to Krebs) and NADH H+ (which go to ETC)
What is the net yield of link reaction?
2 Acetyl CoA per glucose molecule
Decarboxilation
Removing a carbon
What is the net yield of the Krebs cycle?
2 ATP
3 NADH H+
1 FADH2
(Per glucose)
What level of phosphorylation is the Krebs Cycle?
Substrate level
Is Krebs aerobic or anaerobic?
Aerobic
What is the net yield of ATP in ETC?
32 ATP per glucose
ATP Yield of oxidative phosphorylation
32
ATP Yield of ETC
0
ATP Yield of Krebs
2
ATP Yield of link
0
ATP Yield of glycolysis
2
Purpose of glycolysis
Convert glucose into pyruvate
Purpose of link reaction
Convert pyruvate into Acetyl CoA
Purpose of Krebs cycle
Release H+ to electron carriers
Purpose of ETC
Energy pump H+ into inter membrane space
Purpose of oxidative phosphorylation
Produce ATP using ATP synthase
