Which organ breaks down lactic acid?
A
Liver
B
Lung
C
Heart
D
Bladder
Explanation: 

Detailed explanation-1: -Generating glucose (gluconeogenesis): Your liver and kidneys filter lactic acid out of your blood after it’s created in other tissue. They break it down and convert it into new glucose that your body can use for energy in the future.

Detailed explanation-2: -The lactate exits the cells and is transported to the liver, where it is oxidized back to pyruvate and ultimately converted to glucose via the Cori cycle. However, all tissues can use lactate as an energy source, as it can be converted quickly back to pyruvate and enter into the Krebs cycle.

Detailed explanation-3: -Lactic acid is mainly produced in muscle cells and red blood cells. It forms when the body breaks down carbohydrates to use for energy when oxygen levels are low. Times when your body’s oxygen level might drop include: During intense exercise.
