Question

Epinephrine level in blood increases in response to stress. This hormone is known to affect the rate of glycolysis in different organs of the body. The rates of glycolysis in liver, heart and skeletal muscles in response to rise in blood epinephrine (in comparison to non-stress condition) is expected to be

• A. Unaffected in liver, low in heart, and high in skeletal muscles
• B. High in liver, low in heart, and low and skeletal muscles
• C. Unaffected in liver, high in heart, and low in skeletal muscles
• D. Low in liver, high in heart, and high in skeletal muscles

Answer 1

The correct option is D Low in liver, high in heart, and high in skeletal muscles

Epinephrine is the hormone released in response to stress conditions. The rise in the hormone level in he blood causes an increase in ATP production for which the rates of glycolysis increases in the muscles (heart and skeletal muscles). The synthesis of glucose by gluconeogenesis takes place in the liver and so, the rate of glycolysis is low.

Thus, the correct answer is option D.
