Cori Cycle Lactate Recycling

The video tutorial discusses two metabolic pathways involving skeletal muscles: the Cori cycle and the glucose-alanine cycle. It focuses on the role of lactate dehydrogenase in converting pyruvate to lactate under anaerobic conditions and vice versa under aerobic conditions. The Cori cycle is explained in detail, highlighting how lactate produced in muscles is transported to the liver, converted back to glucose, and then returned to muscles as a fuel source. This cycle is crucial during high-intensity exercise when oxygen is limited.

How does the liver utilize lactate produced by skeletal muscles?

What is gluconeogenesis and how is it related to the Cori cycle?

Summarize the key concept of the Cori cycle as described in the text.
