Play an AI-generated podcast conversation about this lesson

What process is promoted by increased cellular metabolism in the nervous system?

Cardiogenesis

Neurogenesis (correct)

Osteogenesis

Dermatogenesis

What is the main purpose of converting lactic acid into lactate in the liver after exercise?

To induce muscle stiffness

To generate fuel for energy production (correct)

To inhibit neurogenesis

To increase muscle fatigue

What happens to lactate after being transformed in the liver following exercise?

It enters circulation to enhance growth and turnover of neurons (correct)

It gets excreted through sweat glands

It remains stored in muscle tissue

It converts back into lactic acid
