aerobic and anaerobic Flashcards
What is aerobic respiration
A series of reactions that converts glucose to CO2 and allows the cell to recover significant amounts of energy
What does aerobic respiration utilize
Utilizes glycolysis, the Krebs cycle, and the electron transport chain
What does aerobic respiration relies on and the characteristic
Relies on free oxygen as the final electron and hydrogen acceptor
Characteristic of many bacteria, fungi, protozoa, and animals
What does anaerobic respiration involve and what gases does it use
Involves glycolysis, the Krebs cycle, and the electron transport chain
Uses NO3-, SO42-, CO33-, and other oxidized compounds as final electron acceptors
What is anaerobic respiration used by
strictly anaerobic organisms and those who are able to metabolize with or without oxygen
What is fermentation
-Incomplete oxidation of glucose
-Oxygen is not required.
-Organic compounds are final electron acceptors
Where does glycolysis take place, how does it split glucose, how much ATP is produced
Takes place in cytoplasm
Splits glucose into 2 pyruvic acids
Small amount of ATP produced
Where does krebs cycle take place
the cytoplasm of bacteria and in the mitochondrial matrix of eukaryotes:
A cyclic metabolic pathway that begins with acetyl CoA, which joins with Oxaloacetic acid and then participates in seven other additional transformations
Krebs cycle
Where does the krebs cycle transfer stored acetyl CoA
to NAD+ and FAD by reducing them (transferring hydrogen ions to them)
NADH and FADH2 function
carry electrons to the electron transport chain
How many ATPS are produced for each molecule of glucose through phosphorylation.
