Which statement correctly describes the body's response to eating a meal

• Insulin changes glucose into glycogen

• Insulin changes glucose into glucagon

• Glucagon causes the liver to store glucose

• Insulin causes the liver to turn glucose into glycogen

• glucagon changes glycogen into glucose

When you haven't eaten in a long time

• sugar levels in the blood will increase

• The liver absorbs glucose

• Pancreas produces more insulin

• Pancreas produces more glucagon

• the liver turns glucagon into glucose and releases it into the blood

Describe how signals are passed across the synapse

• as chemical messengers

• as electricity

• as impulses

• as chemicals

• as electrical impulses

Describe how signals are passed along nerve cells

• as chemical messengers

• as electricity

• as impulses

• as chemicals

• as electrical impulses

Reorder the following

• sensory neurons which pass signal to

• stimuli detected

• muscles receive signal from motor neurons

• by receptors which pass signal to

• Interneurons

Which statement(s) are true about the reflex response

• Interneurons in the CNS pass signal from sensory to motor neurons

• It is a faster response

• It protects the body from danger

• It reduces harm

• are triggered by harmless stimuli

Insulin is released

• by the liver when blood sugar levels decrease

• by the liver when blood sugar levels increase

• by the endocrine gland when blood sugar levels increase

• by the pancreas when blood sugar levels need to be decreased

• by the pancreas when blood sugar levels decrease

select all of the true statements about receptors

• A type of protein found on surface of cells

• detect harmful stimuli

• detect electrical impulses

• are the same shape as the hormone which binds to it

• found on surface of a hormones endocrine gland

Answer explanation

have a complementary shape to the specific hormone

receptors are found on surface of the target tissue not the gland producing the hormone
