1- The function of the Krebs cycle is to break down citric acid and transfer energy to the electron transport chain.

2- Aerobic: 
 1. occurs in presence of oxygen. 
 2. CO2 and water is produced 
 3. lot of energy is liberated

Anaerobic: 
 1. occurs in absence of oxygen 
 2. Lactic Acid or alcohol is produced 
 3. relatively small energy is liberated 

3- The organelle within a cell that performs cellular respiration is the mitochondria. The mitochondria is found in most eukaryotic cells. Its main job is conversion of energy. 

4- The purpose is to use an electrochemical gradient to generate chemical energy in the form of ATP.
