Question

1. which of the following substances cause the liver to release stored sugar when the body requires extra energy? a. cortical steroids b. adrenaline c. estrogen d. norepinephrine 10. ovaries produce which two hormones?

Explanation:

Question 9

To determine which substance causes the liver to release stored sugar for extra energy, we analyze each option:

• Option A (cortical steroids): Primarily involved in inflammation, metabolism regulation (but not direct sugar release from liver for energy), and immune response. Not the main trigger for immediate sugar release.
• Option B (adrenaline): Also called epinephrine, it is released during stress/energy needs. It signals the liver to break down glycogen (stored sugar) into glucose, releasing it into the bloodstream for energy. This matches the scenario.
• Option C (estrogen): A sex hormone (female), involved in reproductive development, not energy-related liver sugar release.
• Option D (norepinephrine): Works with adrenaline in stress response, but its primary role is in blood vessel constriction and heart rate, not direct liver sugar release (adrenaline is more dominant for this function).

Ovaries are female reproductive organs. Their primary hormones are:

• Estrogen: Regulates reproductive development, menstrual cycle, and secondary sex characteristics.
• Progesterone: Prepares the uterus for pregnancy, supports pregnancy, and regulates the menstrual cycle.

Other options (if present, e.g., testosterone in small amounts, but main two are estrogen and progesterone) would be incorrect.

Answer:

B. adrenaline
