What 2 processes are involved in anaerobic respiration?

Answer 1

Anaerobic Respiration can occur in plant and animal cells, in the absence of oxygen.

Animal Cells

C6H12O6 (glucose) ---> 2 lactic acid + 2ATP

Plant Cells

C6H12O6 ---> ethanol + carbon dioxide + 2ATP

The two processes that occur are:

1 - Glycolysis (occurs in the cytosol of cells): The glucose molecule is split into two pyruvate (3- carbon molecules). As a result, energy is released and forms 2 ATP molecules released as well as 2 loaded acceptor molecule called NADH.

-(Since anaerobic respiration occurs in the absence of oxygen, it can no longer continue its journey to the Krebs Cycle and the Electron Transport Chain.)

2 - Fermentation: The hydrogens from the 2 NADH molecules. In animals, The NADs will then reattach these hydrogens onto the middle carbon atom in the pyruvate (3- carbon) molecule. This produces 2 lactic acid molecules, for each pyruvate molecule. In comparison, in plants, ethanol and carbon dioxide is produced.

Answer 2

Although oxygen is not used as the final electron acceptor, the process still uses a respiratory electron transport chain; it is respiration without oxygen. In order for the electron transport chain to function, an exogenous final electron acceptor must be present to allow electrons to pass through the system. In aerobic organisms, this final electron acceptor is oxygen. Molecular oxygen is highly oxidizing and, therefore, is an excellent acceptor. In anaerobes, other less-oxidizing substances such as sulfate (SO42-), nitrate (NO3-), or sulfur (S) are used.

Answer 3

Actually there is two types of anaerobic respiration there is alcoholic fermentation and lactate fermentation.

Answer 4

certain bacteria,fungi,even the germinating seeds when deprived of air respire anaerobically. howdy haahahahaha
