Question

What are two important aspects of lactate metabolism in cardiac myocytes?

Answer 1

Lactate metabolism in cardiac myocytes involves the regulation of blood sugar and the elimination of lactic acid.

Step-by-step explanation:

Two important aspects of lactate metabolism in cardiac myocytes are:

1. Regulation of blood sugar: Lactate produced during anaerobic glycolysis in cardiac myocytes can be converted back into glucose in the liver through a process called the Cori cycle. This glucose can then be released into the bloodstream, helping to regulate blood sugar levels.
2. Elimination of lactic acid: Lactic acid, a byproduct of anaerobic metabolism, can build up in the muscle cells and cause fatigue. Cardiac myocytes have mechanisms to efficiently eliminate lactic acid, preventing its accumulation and ensuring proper muscle function.
