According to the text, what is the 'ketogenic' effect of excessive growth hormone?

Correct answer: It causes such great fat mobilization that large quantities of acetoacetic acid are formed, causing ketosis.

Explanation

This question tests the understanding of a specific metabolic consequence of excessive growth hormone, known as its 'ketogenic' effect, which results from massive mobilization and metabolism of fats.
