Cellular Respiration Flashcards
(28 cards)
What is the main purpose of Glycolysis?
Breakdown 1 glucose to 2 pyruvate molecules.
How much ATP does Glycolysis produce per 1 glucose molecule?
2 ATP
What is the main purpose of Kreb’s Cycle
Creates high energy electrons
How much ATP does Kreb’s Cycle produce per 1 glucose molecule?
2 ATP
What is the main purpose of the ETC
Transfer energy from the electron carriers to even more ATP molecules.
What is the final electron acceptor of the ETC?
Oxygen
How much ATP does ETC produce per 1 glucose molecule?
30-38
How much ATP is produced overall during aerobic cellular respiration?
28-38 ATP
What is glycosis?
A process in which glucose (sugar) is partially broken down by cells in enzyme reactions that do not need oxygen (still can take place with oxygen)
What is the Kreb’s Cycle.
A chain of reactions occurring in the mitochondria where almost all living cells produce energy through.
Where is the Kreb’s Cycle Located?
In the matrix of the Mitochondria
Where is the glycosis process located?
Cytoplasm
Where is the electron transport chain located?
Inner membrane of the mitochondria.
What breaks down glucose into two molecules of pyruvate?
Glycolysis
What has the highest net yield of ATP
ETC
What is powered by acetyl CoA?
Glycolysis
What releases Co2 as a byproduct?
Kreb’s Cycle
What releases H2o as a byproduct?
Electron Transport Chain
What must happen to pyruvate before it can enter the Kreb’s cycle?
It must become acetyl CoA, pyruvate must be oxidized before it can enter the kreb’s cycle
What is oxidization
Loss of electron
What is reduction?
Gain of electeron
What is the role of NADH and FADH2 in the generation of ATP during the Electron Transport Chain of aerobic respioration?
High Energy Electron Carriers
Fermentation is used by organisms who typically perform anaerobic respiration. True or false?
True
Like aerobic respiration, fermentation takes place in the mitochondria of cells, true or false.
False
