AQA GCSE Biology 4.5 Homeostasis and response overview quiz quiz

The regulation of internal conditions to maintain a stable optimum

The steady growth of an organism over time as its cells divide and enlarge

The release of energy from glucose during respiration inside the cells

The spread of pathogens through a population causing disease to break out

A receptor in the skin

The brain

A muscle

A sensory neurone

The heart and the lungs together

The eyes and the ears together

The pancreas and the liver together

The brain and spinal cord

It does not involve the conscious part of the brain

It uses hormones carried in the blood instead of nerves

It uses only one single neurone to carry the whole signal

It does not need a receptor to detect the change at all

An electrical impulse jumping the gap

A chemical (neurotransmitter)

A hormone carried there in the blood

A red blood cell crossing the gap

It is faster and shorter lasting

It uses electrical impulses

It is slower and longer lasting

It acts only on a precise area

The thyroid gland

The pancreas

The two adrenal glands

The pituitary gland

Makes the liver and muscles take up glucose and store it as glycogen

Makes the liver break down its glycogen and release glucose into the blood

Stops the pancreas working so that it can no longer detect glucose levels

Raises the blood glucose concentration even further above the normal level

The body cells gradually stop responding to the insulin produced

The pancreas does not produce enough insulin

Doing far too much vigorous exercise each day

The liver stores up far too much glycogen at once

FSH

Oestrogen

LH

Progesterone

It triggers ovulation so that an egg is released every single day

It thickens the lining of the uterus so an egg cannot implant there

It permanently increases the level of progesterone in the blood

It contains hormones that inhibit FSH so no egg matures

Adrenaline

Insulin

Thyroxine

Progesterone
