Blood glucose regulation

Question 1

what is a hormone?

Answer 1

hormone are chemicals secreted by glands that act as messengers

Question 2

why do target cells only respond to specific hormones?

Answer 2

because target body cells have receptors that recognized and bind to specific hormones

Question 3

target tissue for insulin

Answer 3

liver and fat, helps the uptake of glucose via glut 4 and help regulate blood glucose levels

Question 4

target tissue for glucagon

Answer 4

liver- liver stimulates the breakdown of glyocon back into glucose so it can be used to increase blood sugar

Question 5

write out the stimulus model for blood glucose rising

Answer 5

RISING BLOOD GLUCOSE- BETA CELLS (INSULIN)- LIVER CELLS AND FAT CELLS UPTAKE OF GLUCOSE- DECREASE IN BLOOD GLUCOSE-

Question 6

Write out the stimulus response model for dropping glucose levels

Answer 6

drop in blood glucose- alpha cells (glucagon) - liver cells break down glycogen into usable glucose - increase in blood glucose levels

Question 7

why does type 1 diabetes result in high blood glucose levels

Answer 7

in type one diabetes there is a lack of insulin in the body, due to autoimmunity, body attacks beta cells that make insulin, which is in charge of dropping glucose levels and allows glucose to enter the body

Question 8

explain symptoms of type 1 diabetes

Answer 8

excessive urination- body pees out excess glucose

fatigue- body is cannot uptake glucose to make atp / enegry
increased thirst- over urination
weight loss- low energy, not feeling hungry

Question 9

strats that help achieve lower glucose levels

Answer 9

more frequent smaller meals, count carbs, check insulin dosage and exercise

Question 10

write the chemical equation for photosynthesis

Answer 10

6CO2 + 6H20 - CHLORYPHYL AND LIGHT + C6 H12 06 + 602
